Nitronic 60 Round Bar Supplier for Wear and Galling Resistant Components
Nitronic 60 Round Bar Supplier searches are usually made for a very specific engineering requirement: a material that can handle wear, galling, friction and corrosion without depending entirely on high hardness.
Nitronic 60 is an austenitic stainless steel identified by UNS S21800. It is particularly interesting for components that repeatedly contact, slide, rotate or operate under conditions where conventional stainless steels can experience galling.
The alloy is used in applications including valve components, pump wear rings, fasteners, shafts, pins, bushings, roller-bearing components and other wear-sensitive parts. Technical references also identify ASTM A276 and ASTM A479 for bar products and ASTM A193/A194 for relevant fastener applications.
For an industrial buyer, the important question is not simply “What is Nitronic 60?”
It is:
“Will Nitronic 60 solve the wear, galling and corrosion problem in my component?”

What is Nitronic 60 Round Bar?
Nitronic 60 Round Bar is manufactured from Nitronic 60 austenitic stainless steel, commonly identified by UNS S21800.
The alloy was developed with a combination of chromium, nickel, manganese, silicon and nitrogen that provides a useful balance of:
- Wear resistance
- Galling resistance
- Corrosion resistance
- High strength
- High-temperature oxidation resistance
- Good toughness
- Fabrication capability
One of its most important characteristics is its resistance to galling.
Galling occurs when two metal surfaces in sliding or repeated contact adhere to one another and transfer material between the surfaces.
For valve stems, threaded components, pump parts and sliding components, this can become a serious maintenance problem.
Nitronic 60 is specifically valued because it can resist this type of damage while maintaining an austenitic stainless-steel structure.
Why is Nitronic 60 Different from Ordinary Stainless Steel?
The reason engineers investigate Nitronic 60 is usually not because they simply need another stainless steel.
They are often trying to solve a specific component failure.
For example:
- Threads are seizing.
- A valve stem is galling.
- A pump wear ring is wearing rapidly.
- Sliding surfaces are damaging each other.
- Conventional 304 is not providing sufficient wear resistance.
- 316 is providing corrosion resistance but insufficient mechanical strength.
Nitronic 60 can be considered when the application requires a combination of these characteristics.
Technical material references describe its galling and wear resistance as major advantages and report corrosion performance superior to 304 in many media, with pitting resistance superior to 316.
Nitronic 60 UNS S21800 Designation
The most important designation to remember when sourcing this material is:
UNS S21800
You may also encounter:
- Nitronic 60
- N60
- AISI S21800
- Alloy S21800
- ASTM A276 Nitronic 60
- ASTM A479 Nitronic 60
- ASTM A193 B8S
- ASTM A194 Grade 8S
- AMS 5848
The exact specification should always be matched to the product form.
For example, a round bar and a high-temperature fastener may have different governing standards.
Published technical data associates UNS S21800 with ASTM A276, ASTM A479, ASTM A580, ASTM A193 and ASTM A194 depending on product/application.
Nitronic 60 Specifications
For a Nitronic 60 Round Bar, an industrial purchase specification may include:
| Requirement | Details |
|---|---|
| Material | Nitronic 60 |
| UNS | S21800 |
| Product | Round Bar |
| Standard | ASTM A276 / ASTM A479 where applicable |
| Condition | Annealed / cold worked as required |
| Diameter | Customer requirement |
| Length | Customer requirement |
| Finish | Bright / polished / machined / as required |
| Testing | As specified |
| Certification | MTC as required |
| Inspection | Third-party inspection if required |
For critical applications, the purchase order should identify the exact standard and condition.
Nitronic 60 Chemical Composition
Typical Nitronic 60 chemistry includes significant quantities of chromium, manganese, nickel and silicon.
A representative composition is:
| Element | Typical / Specified Range |
|---|---|
| Carbon | ≤ 0.10% |
| Chromium | 16–18% |
| Nickel | 8–9% |
| Manganese | 7–9% |
| Silicon | 3.5–4.5% |
| Nitrogen | 0.08–0.18% |
| Phosphorus | ≤ 0.06% |
| Sulfur | ≤ 0.03% |
| Iron | Balance |
The exact chemistry should be checked against the applicable material specification and the supplied heat certificate. Published material data for UNS S21800 gives these ranges.
Nitronic 60 Mechanical Properties
Nitronic 60 mechanical properties depend on the material condition.
This is especially important when comparing annealed bar with cold-worked material.
For example, published data for level-1 cold-worked Nitronic 60 reports a minimum tensile strength around 759 MPa and yield strength around 621 MPa, while more heavily cold-worked conditions can reach considerably higher strength.
This demonstrates why an engineer should never specify simply:
“Nitronic 60 — high tensile strength.”
The required condition should be clearly stated.
Nitronic 60 Tensile Strength
Nitronic 60 tensile strength can vary considerably depending on the amount of cold working.
A technical data source lists:
Level 1 cold worked:
- Tensile strength: ≥759 MPa
- Yield strength: ≥621 MPa
- Elongation: ≥35%
A more heavily cold-worked condition can reach:
- Tensile strength: ≥1,379 MPa
- Yield strength: ≥1,241 MPa
These values illustrate how strongly processing condition can affect the alloy’s mechanical performance.
For an actual purchase, the required specification and MTC should take priority over generic online property tables.
Nitronic 60 Yield Strength
Yield strength is particularly important for shafts, pins, fasteners and loaded mechanical components.
Nitronic 60 can achieve considerably higher yield strength through cold working.
This gives designers the possibility of using smaller cross-sections in some applications while maintaining the required mechanical strength.
However, reducing component size should only be done after engineering calculations and application-specific validation.
Nitronic 60 Hardness
Nitronic 60 is not simply a hard alloy in the conventional sense.
Its anti-galling performance is a major part of what makes it interesting.
That is an important distinction.
A material does not necessarily need extremely high hardness to provide excellent resistance to galling.
Nitronic 60’s microstructure and alloy chemistry contribute to its wear and galling behaviour.
For this reason, selecting the alloy solely by comparing hardness values can lead to a poor material decision.
Why Nitronic 60 Resists Galling
Galling can occur when two metal surfaces experience:
- Sliding contact
- Pressure
- Repeated movement
- Insufficient lubrication
- Surface adhesion
Threads are particularly vulnerable.
A stainless-steel bolt and nut can become difficult or impossible to separate after severe galling.
Nitronic 60 was developed specifically with anti-galling performance in mind.
Technical sources identify its resistance to wear, tearing and freeze-up as one of its defining characteristics.
This makes it relevant for:
- Valve stems
- Fasteners
- Pump components
- Bushings
- Pins
- Sliding parts
- Wear rings
Nitronic 60 Wear Resistance
Nitronic 60 can be used where repeated mechanical contact causes wear.
Applications can involve:
Metal-to-metal contact
Sliding surfaces
Rotating components
Threaded assemblies
Valve movement
Pump wear surfaces
Published data describes the alloy as wear resistant even though its performance does not depend simply on having the hardness of cobalt- or nickel-based wear alloys.
Nitronic 60 Corrosion Resistance
Nitronic 60 is also a corrosion-resistant alloy.
Its chromium and nickel content provides stainless-steel corrosion resistance, while its composition gives it useful performance in environments where wear and corrosion occur together.
This combination can be valuable in:
- Chemical processing
- Petrochemical equipment
- Pump systems
- Valves
- Food-processing equipment
- Pharmaceutical machinery
Technical references report corrosion resistance better than Type 304 in many media.
Nitronic 60 Pitting Resistance
Pitting is a localized form of corrosion that can create small but deep cavities in a metal surface.
For equipment exposed to chloride-containing environments, pitting resistance can become a significant material-selection factor.
Nitronic 60 has been reported to have pitting resistance superior to 316 stainless steel in relevant comparisons.
However, this does not mean Nitronic 60 should automatically replace 316 in every chloride environment.
The actual concentration, temperature, stress and process chemistry should be evaluated.
Nitronic 60 High-Temperature Performance
Nitronic 60 was originally developed as a high-temperature alloy.
Its oxidation resistance at elevated temperature is reported to be comparable to Type 309 stainless steel and substantially better than Type 304 stainless steel.
This makes the alloy relevant to components that experience both:
mechanical wear + elevated temperature
rather than applications where corrosion is the only concern.
Nitronic 60 Applications
Nitronic 60 Round Bar can be machined into a wide variety of components.
Common application areas include:
- Valve stems
- Valve seats
- Valve trim
- Pump wear rings
- Shafts
- Pins
- Bushings
- Roller-bearing components
- Fasteners
- Nuts
- Bolts
- Studs
- Chain components
- Screening components
- High-wear mechanical parts
Technical references specifically identify valve components, pump wear rings, nuts, bolts, pins, bushings and roller-bearing applications.
Nitronic 60 Valve Components
Valve stems and valve trim can experience repeated movement and metal-to-metal contact.
If the material begins to gall, the valve may become difficult to operate and maintenance requirements can increase.
Nitronic 60 can therefore be considered for:
- Valve stems
- Valve seats
- Valve trim
- Actuator-related components
- Sliding valve components
This is one of the more commercially important applications for the alloy.
Nitronic 60 Pump Components
Pumps can expose components to a combination of:
- Fluid exposure
- Pressure
- Friction
- Sliding contact
- Vibration
- Wear
Nitronic 60 is used in applications such as pump wear rings and related components where anti-galling and wear resistance are important.
Nitronic 60 Shafts, Pins and Bushings
Round bar is particularly useful when the final component will be machined.
Nitronic 60 Round Bar can therefore be considered for:
- Shafts
- Pins
- Bushes
- Rollers
- Spacers
- Mechanical sleeves
- Bearing components
The advantage is that the same material can provide both corrosion resistance and resistance to mechanical wear.
Nitronic 60 Fasteners
Fasteners are one of the most interesting applications for Nitronic 60 because galling can become a serious problem in stainless-steel threaded assemblies.
Nitronic 60 can be used for:
- Bolts
- Nuts
- Studs
- Threaded components
Technical references associate UNS S21800 with ASTM A193 and ASTM A194 fastener grades.
Nitronic 60 Bolts and Nuts
If a stainless-steel bolt and nut repeatedly seize during assembly or maintenance, simply applying more torque may make the problem worse.
Material selection becomes important.
Nitronic 60 can be considered for applications where threaded components require resistance to galling and wear.
The final fastener specification should nevertheless be confirmed according to:
- Diameter
- Thread
- Strength requirement
- Temperature
- Service environment
- Applicable ASTM specification
- Required coating or lubrication
Nitronic 60 Machining
Nitronic 60 can be machined, but its work-hardening behaviour needs to be considered.
Good machining practice generally includes:
- Rigid machine setup
- Sharp tooling
- Proper feed
- Controlled cutting speed
- Adequate coolant
- Avoiding unnecessary tool rubbing
Technical guidance for the alloy recommends positive feeds and controlled cutting speeds.
The exact machining parameters should be developed for the particular material condition and machine setup.
Nitronic 60 Welding
Nitronic 60 can be welded using commonly used welding processes.
Depending on the fabrication requirement, processes can include:
- GTAW
- GMAW
- Submerged arc welding
The appropriate filler and welding procedure should be selected according to the required joint properties and applicable specification.
Critical industrial assemblies may require qualified WPS/PQR documentation and inspection.
Nitronic 60 Heat Treatment
Nitronic 60 behaves differently from precipitation-hardening alloys such as A286.
Its strength can be increased substantially through cold working rather than relying on a conventional precipitation-aging treatment.
This is an important distinction for engineers comparing Nitronic 60 with other specialty alloys.
Material condition should therefore be specified clearly when ordering.

Nitronic 60 vs 304 Stainless Steel
The question “Nitronic 60 vs 304” often comes up when a conventional stainless-steel component is experiencing wear or galling.
304 is widely used for general corrosion resistance and fabrication.
Nitronic 60 is more specialized.
It offers:
- Greater galling resistance
- Higher wear resistance
- High-temperature oxidation resistance
- High strength in appropriate conditions
Technical data also reports Nitronic 60 corrosion performance better than 304 in many media.
If your component is failing specifically because of galling, changing from 304 to another conventional stainless grade may not address the underlying problem.
Nitronic 60 vs 316 Stainless Steel
316 is well known for corrosion resistance, particularly in many chloride-containing applications.
Nitronic 60 brings another advantage into the selection:
anti-galling and wear resistance.
Technical data reports pitting resistance superior to Type 316 while also identifying Nitronic 60 as an anti-galling alloy.
However, material selection should always be based on the complete chemical and mechanical environment.
Nitronic 60 Round Bar Price
The price of Nitronic 60 Round Bar depends on several factors:
- Diameter
- Length
- Quantity
- Material condition
- ASTM specification
- Surface finish
- Testing requirements
- Certification
- Stock availability
- Market conditions
Because Nitronic 60 is a specialty alloy, it should not be priced like standard 304 or 316 round bar.
For a meaningful quotation, send the complete requirement.
