Nitronic 60 Galling Resistance in Industrial Components
Galling is a form of adhesive wear that can occur when two metal surfaces slide against each other under pressure. Small areas of contact may adhere, transfer material and eventually cause scoring, seizure or difficulty disassembling a component.
In industrial equipment, galling can affect threaded fasteners, valve assemblies, sliding parts and other components that experience repeated metal-to-metal contact.
Nitronic 60, also known as UNS S21800, is an austenitic stainless steel developed with strong resistance to galling and wear in suitable applications. Its performance makes it a material worth considering when conventional stainless steel components experience repeated contact-related damage.
This guide explains how galling occurs, why Nitronic 60 is considered for anti-galling applications, which industrial components may benefit from it, and what buyers should verify before sourcing the material.
What Is Nitronic 60?
Nitronic 60 is a nitrogen-strengthened austenitic stainless steel known for its resistance to galling and its useful corrosion and wear characteristics.
It is commonly identified by the following designation:
| Parameter | Information |
|---|---|
| Material name | Nitronic 60 |
| UNS designation | S21800 |
| Material family | Austenitic stainless steel |
| Key engineering characteristic | Resistance to galling and adhesive wear |
| Potential product form | Round bar and other forms, subject to specification and availability |
| Typical engineering interest | Sliding contact, fasteners, valve parts and wear-prone components |
The exact mechanical properties depend on the product form, manufacturing route, condition and applicable specification.

What Is Galling in Metal Components?
Galling occurs when contacting metal surfaces adhere locally during sliding or repeated movement. Under sufficient contact pressure, surface material can transfer from one component to another, creating roughness, scoring or seizure.
It can occur in threaded assemblies, sliding mechanisms, valve components and other equipment where metal surfaces interact under load.
Common causes of galling
High contact pressure: Concentrated loads can increase the risk of adhesive contact between surfaces.
Repeated sliding: Repeated movement can damage surface films and promote material transfer.
Incompatible surface conditions: Material pairing, surface finish, hardness and manufacturing condition can influence galling behaviour.
Insufficient lubrication: In applications designed for lubrication, inadequate lubricant can increase friction and surface damage.
Contamination and assembly practices: Incorrect installation, surface damage and unsuitable assembly procedures can contribute to premature failure.
Galling is not determined by alloy composition alone. Component geometry, surface finish, lubrication, load, movement and operating environment all matter.
Why Is Nitronic 60 Used for Galling Resistance?
Nitronic 60 is known for its resistance to galling compared with many conventional stainless steel combinations in suitable test and service conditions.
Its alloy design helps provide resistance to adhesive wear while retaining useful corrosion resistance and mechanical properties.
1. Resistance to adhesive wear
Nitronic 60 is considered for applications where contacting metal surfaces may otherwise experience scoring, material transfer or seizure.
This can be relevant to sliding components and assemblies that require repeated movement.
2. Potential for reduced galling-related maintenance
When the alloy is properly selected and the component is correctly designed, Nitronic 60 may help reduce galling-related damage.
However, it does not eliminate every wear mechanism or guarantee a specific service life. Performance must be validated under the actual operating conditions.
3. Corrosion resistance
Nitronic 60 offers corrosion resistance in many environments. Its suitability depends on the specific fluid, concentration, temperature and exposure conditions.
Resistance to galling should not be confused with universal corrosion resistance.
4. Suitability for selected mechanical components
Nitronic 60 can be considered for parts where contact, sliding or repeated movement is an important design concern.
The required product form, material condition, dimensional tolerances and specifications must be established before procurement.
Industrial Components That May Benefit from Nitronic 60
Threaded fasteners
Threaded metal components can experience galling during tightening, removal or repeated assembly.
Nitronic 60 may be considered for suitable fasteners where galling is a known concern. The final choice should account for thread geometry, contact pressure, installation torque, lubrication, temperature and the applicable fastener specification.
Do not assume that using Nitronic 60 alone guarantees that threaded assemblies will never seize.
Valve components
Some valve components experience repeated movement and metal-to-metal contact during operation.
Nitronic 60 may be considered for suitable stems, internal components or sliding parts when the material’s properties meet the engineering requirements.
The choice should also consider the fluid, pressure, temperature, sealing arrangement and required dimensional stability.
Pump and mechanical components
Selected pump and machinery components may experience rubbing, sliding contact or repeated mechanical movement.
Nitronic 60 can be evaluated for suitable components where galling resistance is important. Designers should also assess lubrication, shaft alignment, surface finish, wear mechanisms and the mechanical loading involved.
Sliding and positioning mechanisms
Guides, positioning parts and other sliding mechanisms may benefit from materials that resist adhesive wear.
Nitronic 60 can be considered where its galling resistance, strength and corrosion behaviour meet the intended operating conditions.
Industrial fittings and specialised hardware
Some fittings and mechanical assemblies involve repeated contact between metal surfaces. Nitronic 60 may be suitable when supported by the component design and governing specification.
These are potential application categories, not a guarantee that every component should use Nitronic 60.
Nitronic 60 Versus General Anti-Galling Measures
Choosing a suitable material is only one part of controlling galling. Assembly and design practices can be equally important.
| Engineering factor | Why it matters |
|---|---|
| Material pairing | The combination of contacting alloys affects adhesive wear behaviour |
| Surface finish | Roughness and surface damage can influence contact conditions |
| Lubrication | Suitable lubrication can reduce friction where permitted by the application |
| Contact pressure | Excessive local loading can increase the risk of surface damage |
| Alignment | Poor alignment can concentrate loads and cause uneven contact |
| Assembly procedure | Correct installation methods can help reduce damage during tightening or movement |
| Operating environment | Temperature, contamination and corrosion can influence component performance |
Nitronic 60 should be evaluated as part of a complete engineering solution rather than treated as a substitute for proper design, lubrication or installation practices.
Nitronic 60 Material Specifications and Procurement
When purchasing Nitronic 60, specify the material designation and the requirements relevant to the actual product.
For bar products, ASTM A276/A276M is a commonly referenced specification for stainless steel bars and shapes, but the applicable grade coverage and purchase requirements must be verified against the current edition.
Other product forms may be governed by different specifications. Do not assume that a bar specification automatically applies to fasteners, finished components, plate or other forms.
Useful technical references:
What should buyers specify?
Include the following information in a purchase enquiry:
- Material: Nitronic 60 / UNS S21800
- Product form: round bar or another required form
- Diameter, thickness, length and tolerances, as applicable
- Applicable ASTM or customer specification
- Required material condition
- Quantity
- Material test certificate and traceability requirements
- Additional inspection or testing requirements
- Delivery location and required schedule
For components intended to resist galling, it is also helpful to describe the intended application, contacting material, movement, lubrication and operating environment. These details help the engineering team assess whether the proposed material is appropriate.
