A286 Round Bar Supplier is a highly specific sourcing requirement for industries looking for a material that can combine high strength, corrosion resistance and elevated-temperature performance.
Alloy A286 is an age-hardening austenitic stainless steel developed for demanding engineering applications.
It is commonly identified by:
UNS S66286
The alloy is also associated with Grade 660 and specifications such as ASTM A638, depending on the product and application.
Why does an engineer consider A286 instead of a conventional stainless-steel round bar?
Because some components have to work under conditions where ordinary stainless steel may not provide the required combination of strength and temperature performance.
A286 is therefore used in selected applications involving:
- High mechanical loads
- Elevated temperatures
- Corrosive environments
- Repeated thermal exposure
- High-strength fastening
- Turbine equipment
- Aerospace components

What is A286 Round Bar?
A286 Round Bar is a round-section product manufactured from Alloy A286, an iron-based precipitation-hardening austenitic stainless steel.
The alloy contains significant amounts of:
- Nickel
- Chromium
- Iron
along with additions such as titanium and other alloying elements.
Its principal attraction is the ability to achieve high strength through age hardening while maintaining useful corrosion resistance.
This combination makes A286 different from many conventional austenitic stainless-steel grades.
Round bar is commonly used as a starting material for manufacturing:
- Bolts
- Nuts
- Studs
- Shafts
- Pins
- Bushings
- Springs
- Turbine components
- Precision machined parts
Why is Alloy A286 Used in Industry?
A material becomes valuable when it solves a manufacturing or operating problem.
For A286, that problem is often:
How do we obtain high mechanical strength without giving up useful corrosion resistance and elevated-temperature capability?
A286 can be age hardened to develop substantially higher strength than ordinary annealed austenitic stainless steels.
This makes it useful for components where:
- Space is limited
- Weight reduction matters
- High clamping loads are required
- Temperature is elevated
- Corrosion resistance is necessary
The alloy is therefore frequently associated with high-performance fastening and mechanical components.
What is UNS S66286?
The UNS designation for Alloy A286 is:
UNS S66286
Industrial purchasing documents may also identify the alloy using names such as:
- A286
- Alloy A286
- 660 Stainless Steel
- Grade 660
- UNS S66286
- A286 Stainless Steel
When requesting material, it is better to mention both the grade and UNS number.
This helps reduce confusion between similar-looking specialty alloys.
A286 Material Designation
Depending on the product form and application, A286 may be covered by different standards.
One important specification is:
ASTM A638 — Grade 660
This specification relates to heat-resisting alloy-steel forgings for turbine applications and includes Grade 660 material.
For bar products, the exact applicable specification should be confirmed with the purchaser and supplier.
Standards should never be assumed simply from the alloy name.
For industrial procurement, the purchase order should clearly identify:
Grade + UNS + specification + product form + condition + dimensions.
ASTM standards can be checked through ASTM International.
A286 Chemical Composition
A286 obtains its properties from its carefully controlled alloy chemistry.
Major alloying elements include:
| Element | General Function |
|---|---|
| Chromium | Corrosion and oxidation resistance |
| Nickel | Austenitic structure and stability |
| Titanium | Precipitation strengthening |
| Molybdenum | Strength and corrosion contribution |
| Manganese | Alloying and processing control |
| Silicon | Metallurgical control |
| Carbon | Controlled to specification |
| Boron | Strengthening contribution |
The exact chemical limits depend on the applicable specification.
For critical industrial purchases, the chemistry should be verified against the Material Test Certificate.
A286 Mechanical Properties
A286 is particularly attractive because its mechanical properties can be significantly improved through suitable heat treatment.
Important properties include:
- Tensile strength
- Yield strength
- Elongation
- Hardness
- Fatigue performance
- Creep resistance at elevated temperature
The actual values depend heavily on the material condition.
A buyer should therefore avoid treating one generic mechanical-property table as applicable to every A286 round bar.
The heat-treatment condition matters.
A286 Tensile Strength
A286 can achieve high tensile strength after appropriate precipitation-hardening treatment.
This is one reason it is selected for high-strength components such as:
- Fasteners
- Bolts
- Studs
- Shafts
- Turbine hardware
- Aerospace components
When tensile strength is specified, the purchaser should identify the required material condition and applicable standard.
A286 Yield Strength
Yield strength is particularly important for fasteners and mechanically loaded components.
A286 can provide high yield strength following suitable aging treatment.
This allows designers to use the material in components where high loads are transferred through relatively small cross-sections.
For critical designs, engineers should use the certified properties for the exact heat-treatment condition rather than a generic online value.
A286 Hardness
A286 hardness varies according to:
- Heat treatment
- Aging condition
- Cold work
- Product form
Age-hardening treatment can significantly increase hardness and strength.
Consequently, the material condition should always accompany a hardness requirement.
For example, simply requesting:
“A286 Round Bar, HRC ___”
may not be sufficient.
A more complete enquiry specifies the applicable standard and heat-treatment condition.
A286 Corrosion Resistance
A286 provides useful corrosion resistance in many industrial environments.
Its chromium content contributes to its stainless-steel corrosion performance.
The alloy is therefore considered where both:
high strength + corrosion resistance
are required.
Potential applications include:
- Industrial equipment
- Turbine systems
- Fasteners
- Aerospace components
- High-temperature machinery
However, corrosion resistance depends on the actual service environment.
Temperature, chemicals, chloride exposure and stress conditions should be evaluated for critical applications.
A286 High Temperature Performance
High-temperature performance is one of the most important reasons engineers investigate A286.
The alloy can maintain useful strength at elevated temperatures compared with many conventional stainless steels.
This makes it relevant to components exposed to:
- Hot gases
- Thermal cycling
- Elevated mechanical loads
- Turbine environments
- High-temperature machinery
The actual temperature capability depends on stress, exposure duration and component design.
A286 should therefore be selected according to the actual operating conditions rather than temperature alone.
A286 Precipitation Hardening
The term precipitation hardening is central to understanding A286.
The alloy can be heat treated so that fine strengthening precipitates form within its microstructure.
This increases mechanical strength.
The general sequence involves:
solution treatment → controlled cooling → aging → strengthening
The exact treatment depends on the required material condition and governing specification.
This is why A286 is sometimes described as a precipitation-hardening stainless steel.
A286 Heat Treatment
A286 can undergo solution treatment followed by aging to develop its required mechanical properties.
A typical industrial process may involve:
- Solution treatment
- Cooling
- Aging treatment
- Controlled cooling
Exact temperatures, holding times and cooling procedures should be taken from the applicable material specification or approved heat-treatment procedure.
Do not apply a generic heat-treatment schedule to a critical component without confirming the applicable specification.
