What is Alloy A286 Round Bar?
Alloy A286 Round Bar is a round-section product manufactured from A286 precipitation-hardening stainless alloy.
It is an iron-based alloy that combines:
- Chromium
- Nickel
- Titanium
- Molybdenum
- Manganese
- Silicon
- Controlled carbon
The alloy can achieve high mechanical properties through appropriate precipitation-hardening treatment.
This makes A286 useful for demanding components where ordinary stainless steel may not provide sufficient strength.
Why is A286 Used in Industry?
Industrial components can face several challenges simultaneously.
A fastener, shaft or mechanical component may need to withstand:
high load + temperature + corrosion + vibration.
Selecting a material based on only one of these factors can lead to problems later.
A286 is attractive because it offers a balanced combination of properties.
The alloy is therefore used in selected applications involving:
- High mechanical loads
- Elevated temperatures
- Corrosive environments
- High-performance fasteners
- Precision components
Technical information on A286 can also be reviewed through Carpenter Technology’s A-286 alloy information, which provides information on the alloy, specifications and typical applications.
What is UNS S66286?
The commonly recognized UNS designation for A286 is:
UNS S66286
Industrial enquiries can therefore use several different terms:
- Alloy A286
- A-286
- A286 stainless steel
- UNS S66286
- Grade 660
- 660 stainless steel
- A286 Round Bar
However, these terms should not be treated as automatically interchangeable for every application.
The purchaser should confirm the required specification and product form before ordering.
A286 Material Designation
A286 appears in several industrial specifications depending on the product form.
For example, ASTM A638/A638M covers precipitation-hardening iron-base superalloy bars and forgings for high-temperature service.
A286 is also associated with ASTM A453/A453M Grade 660 for certain high-temperature bolting applications.
For critical procurement, the buyer should specify the exact standard rather than simply writing “A286.”
The ASTM International standards database can be used as a reference when identifying the applicable material standard.
A286 Chemical Composition
A286 derives its properties from a carefully controlled alloy chemistry.
Major alloying elements include:
| Element | Importance |
|---|---|
| Chromium | Corrosion resistance |
| Nickel | Austenitic structure and stability |
| Titanium | Precipitation strengthening |
| Molybdenum | Strength and corrosion resistance |
| Manganese | Metallurgical control |
| Silicon | Deoxidation and processing |
| Carbon | Controlled for material performance |
The exact chemical limits depend on the applicable specification.
For industrial procurement, chemical composition should be verified through the Material Test Certificate.
A286 Mechanical Properties
A286 can achieve high mechanical properties through precipitation hardening.
Important characteristics include:
- High tensile strength
- High yield strength
- Good ductility
- Good corrosion resistance
- Elevated-temperature strength
The actual mechanical properties depend heavily on the material condition and heat treatment.
This is particularly important with A286.
Two bars with the same grade designation can have different mechanical properties if supplied in different conditions.
A286 Tensile Strength
A286 can provide significantly higher tensile strength than many general-purpose stainless steels when properly precipitation hardened.
This makes it useful for highly loaded components.
Potential applications include:
- High-strength fasteners
- Bolts
- Shafts
- Pins
- Turbine components
- Aerospace hardware
The specified tensile strength should always be verified against the required condition and applicable specification.
A286 Yield Strength
Yield strength is particularly important for components that operate under continuous mechanical loading.
A286 can achieve high yield strength through precipitation-hardening treatment.
This allows engineers to use the alloy in applications where permanent deformation must be minimized.
For critical components, the required:
yield strength + tensile strength + hardness
should be specified before ordering.
A286 Hardness
A286 hardness depends on the supplied condition and precipitation-hardening treatment.
Hardness may be specified using:
- Rockwell
- Brinell
- Vickers
However, hardness should not be treated as a substitute for the complete mechanical specification.
The Material Test Certificate should be checked to confirm that the delivered material meets the required condition.
A286 Precipitation Hardening
One of the defining characteristics of A286 is its ability to develop high strength through precipitation hardening.
During suitable heat treatment, strengthening phases form within the alloy’s microstructure.
This significantly increases mechanical strength.
The heat-treatment route is therefore a critical part of A286 material selection.
For engineering procurement, don’t specify only:
A286 Round Bar
Also specify the required condition and mechanical properties.
A286 Heat Treatment
A286 heat treatment generally involves solution treatment followed by an aging or precipitation-hardening treatment.
The exact temperature, holding time and cooling method depend on the applicable specification and required condition.
A typical industrial sequence may involve:
Solution treatment → cooling → precipitation aging
The objective is to develop the required mechanical properties while maintaining suitable dimensional stability.
For critical components, the heat-treatment procedure should be controlled and documented.
A286 High-Temperature Performance
A286 is frequently considered when components must maintain useful strength at elevated temperatures.
Potential applications include:
- High-temperature fasteners
- Turbine components
- Engine components
- Power-generation equipment
- Industrial heating systems
However, elevated-temperature suitability depends on:
- Operating temperature
- Stress
- Exposure duration
- Environment
- Component geometry
- Required life
The alloy should therefore be evaluated using the actual service conditions.
A286 Corrosion Resistance
A286 provides good corrosion resistance in many industrial environments.
This is another reason it is useful where a high-strength material must also tolerate corrosive conditions.
Potential environments include:
- Industrial processing
- Power generation
- Petrochemical equipment
- Aerospace systems
- High-temperature mechanical assemblies
For severe chemical environments, compatibility should always be checked against the specific fluid and operating conditions.
A286 Round Bar Specifications
When ordering A286 Round Bar, provide the following:
| Requirement | Example |
|---|---|
| Grade | A286 |
| UNS | S66286 |
| Standard | ASTM A638 / applicable specification |
| Diameter | 50 mm |
| Length | 3000 mm |
| Condition | Solution treated / aged |
| Finish | Bright / ground |
| Quantity | 250 kg |
| Testing | As required |
| Certificate | MTC |
A complete specification reduces the risk of receiving a material that is technically the correct alloy but supplied in an unsuitable condition.
A286 Fasteners and Bolts
A286 is widely associated with high-performance fasteners.
Fasteners can experience:
- High tensile loads
- Elevated temperatures
- Vibration
- Corrosive environments
- Thermal cycling
A286 can be considered for selected:
- Bolts
- Nuts
- Studs
- Screws
- High-temperature fasteners
For certain high-temperature bolting applications, ASTM A453/A453M includes Grade 660 materials.
The exact fastener specification should always be confirmed against the engineering drawing and service requirements.
A286 Shafts and Precision Components
A286 Round Bar can be machined into high-strength components such as:
- Shafts
- Pins
- Spindles
- Bushings
- Couplings
- Precision mechanical parts
It is particularly relevant where the component needs higher strength than a conventional austenitic stainless steel can provide.
A286 Aerospace Applications
A286 has been used for selected aerospace and aircraft-engine applications because of its strength and temperature capability.
Potential applications include:
- Engine components
- Fasteners

Its strength and work-hardening characteristics require careful machining control.
Important factors include:
- Cutting speed
- Feed
- Tool geometry
- Cutting depth
- Coolant
- Tool rigidity
Machining parameters should be optimized according to the material condition.
For precision components, controlling heat generation during machining is also important.
A286 Welding
A286 can be welded using suitable procedures.
However, the welding process may influence the final mechanical properties and precipitation-hardening condition.
For critical applications, welding should therefore be performed using a qualified procedure.
Post-weld heat treatment requirements should be determined according to:
- Component design
