What is Alloy A286 Round Bar?
Alloy A286 Round Bar is an iron-based precipitation-hardening alloy containing chromium, nickel, molybdenum, titanium and aluminum.
Unlike conventional stainless steels that rely mainly on solid-solution strengthening, A286 can be strengthened through controlled precipitation heat treatment.
This makes it particularly interesting for components where the buyer requires a combination of:
- High tensile strength
- High yield strength
- Corrosion resistance
- Elevated-temperature strength
- Good oxidation resistance
- Resistance to deformation under sustained loads
- Fabrication versatility
The material is therefore frequently considered for high-temperature fasteners, aerospace components, shafts, turbine-related components and industrial equipment.
Why is A286 Used in Demanding Industries?
A286 occupies an interesting position between conventional stainless steels and more specialized nickel-based high-temperature alloys.
An engineering team may consider A286 when the component requires considerably more strength than a conventional stainless-steel grade can provide while still requiring corrosion resistance.
Its precipitation-hardening capability is one of its biggest advantages.
The final properties depend significantly on the heat-treatment condition.
That means two A286 bars with the same nominal chemical composition can have very different mechanical properties if supplied in different conditions.
For procurement teams, this makes the material condition just as important as the grade designation.
A286 Equivalent Grades and Designations
A286 may appear under different designations depending on the product form and specification.
| Designation | Reference |
|---|---|
| A286 | Common alloy designation |
| UNS S66286 | UNS designation |
| Grade 660 | Common specification designation |
| ASTM A638 | High-temperature alloy bars |
| ASTM A453 | High-temperature bolting |
| AMS 5731 | Aerospace material specification |
| AMS 5732 | Aerospace material specification |
A purchaser should always confirm which standard applies to the particular product being ordered.
For example, an A286 round bar intended for a machined component may have different documentation requirements from A286 fasteners manufactured to a bolting specification.
A286 Chemical Composition
Typical Alloy A286 chemistry contains:
| Element | Typical Content |
|---|---|
| Carbon | Controlled low level |
| Manganese | Controlled |
| Silicon | Controlled |
| Chromium | Approximately 13.5–16% |
| Nickel | Approximately 24–27% |
| Molybdenum | Approximately 1–1.5% |
| Titanium | Approximately 1.9–2.35% |
| Aluminum | Approximately 0.35% |
| Vanadium | Small controlled addition |
| Boron | Controlled |
| Iron | Balance |
Exact limits depend on the governing specification.
For an industrial purchase, the chemistry should always be verified against the Material Test Certificate (MTC) for the supplied heat.
A286 Mechanical Properties
A286 mechanical properties depend strongly on the material condition.
Important parameters include:
- Yield strength
- Tensile strength
- Elongation
- Reduction of area
- Hardness
- Fatigue performance
- Creep resistance
- Stress-rupture performance
The alloy can achieve substantially higher strength after appropriate precipitation-hardening treatment.
This is one of the main reasons A286 is selected for high-strength applications where corrosion resistance is also required.
A286 Tensile Strength and Yield Strength
Searches such as:
“A286 tensile strength”
and
“A286 yield strength”
are common among engineers preparing material selections.
However, there is no single mechanical-property value that should be applied to every A286 bar.
The final value depends on:
- Product size
- Heat treatment
- Applicable specification
- Test temperature
- Material condition
For this reason, purchasing documents should specify the required condition instead of simply stating A286 Round Bar.
A286 Hardness
A286 hardness varies according to the heat-treatment condition.
The alloy may be supplied in a solution-treated condition and subsequently precipitation hardened to develop higher strength and hardness.
A buyer requiring a specific hardness should mention:
Required hardness + test method + material condition
For example:
- Rockwell hardness
- Brinell hardness
- Vickers hardness
The supplier’s MTC should then be checked against the purchase requirement.
A286 High-Temperature Performance
One of the strongest reasons for considering A286 is its performance at elevated temperatures.
Components operating at higher temperatures can experience:
- Loss of strength
- Thermal expansion
- Creep
- Oxidation
- Stress relaxation
A286 was developed for applications where elevated-temperature strength is important.
It is therefore frequently associated with:
- High-temperature fasteners
- Turbine components
- Engine components
- Aerospace hardware
- Industrial heat-related equipment
The actual service temperature should always be evaluated against the specific application and specification.
A286 Creep and Stress-Rupture Resistance
For components exposed to sustained loads at elevated temperature, tensile strength alone does not tell the complete story.
Creep is the gradual deformation of a material under sustained stress at elevated temperature.
Stress rupture concerns the time a material can withstand a specified stress and temperature before failure.
A286 is valued in applications where these characteristics matter.
This makes it more suitable for certain elevated-temperature components than ordinary 304 or 316 stainless steel.
A286 Corrosion Resistance
A286 contains significant chromium and nickel, giving it useful corrosion resistance.
It can be considered where the component requires both:
strength + corrosion resistance
rather than strength alone.
However, A286 should not automatically be treated as a replacement for every corrosion-resistant alloy.
The actual environment matters.
Factors such as:
- Chloride exposure
- Acidity
- Temperature
- Moisture
- Stress
- Chemical concentration
can influence material performance.
A286 Precipitation Hardening
The defining feature of A286 is its ability to develop higher strength through precipitation hardening.
The process involves controlled heat treatment that allows strengthening phases to form within the alloy’s microstructure.
This is fundamentally different from simply cold-working a conventional stainless steel.
The final mechanical properties therefore depend on maintaining proper control over:
- Solution treatment
- Cooling
- Aging temperature
- Aging time
- Section size
A286 Heat Treatment
A typical A286 heat-treatment sequence may involve:
Solution treatment → cooling → precipitation aging
The exact parameters should be selected according to the applicable specification and required material condition.
Heat treatment is particularly important because the alloy’s final strength is strongly dependent on its precipitation-hardening cycle.
For critical aerospace or high-temperature applications, the heat-treatment records may form an important part of the material documentation.
A286 Solution Annealing
Solution treatment is used to establish an appropriate starting microstructure before precipitation hardening.
The material is heated to the specified solution-treatment temperature and held for the required period before controlled cooling.
The exact temperature and time depend on:
- Product size
- Specification
- Manufacturing route
- Required condition
Industrial buyers should therefore request the applicable heat-treatment condition rather than copying a generic temperature from an online source.
A286 Aging Treatment
After solution treatment, A286 can be age hardened.
During aging, strengthening precipitates form within the alloy.
The aging cycle influences:
- Yield strength
- Tensile strength
- Hardness
- Ductility
- High-temperature performance
This is why A286 age-hardening condition should be clearly identified when ordering material for critical applications.
A286 Machining
A286 machining requires appropriate cutting conditions because the alloy is stronger and more work-hardening-sensitive than conventional stainless steels.
Machining considerations can include:
- Proper cutting speed
- Adequate feed
- Rigid tooling
- Suitable carbide tooling
- Effective coolant
- Avoiding unnecessary dwell
- Maintaining a consistent cutting engagement
Machining parameters should be selected according to the material condition.
Solution-treated A286 and precipitation-hardened A286 will not behave identically during machining.
A286 Welding
A286 can be fabricated using appropriate welding procedures.
For industrial fabrication, welding parameters should be established according to:
- Product condition
- Joint design
- Thickness
- Welding process
- Filler material
- Required post-weld properties
Critical applications may require qualified welding procedures and inspection.
For aerospace or high-temperature applications, documentation requirements can be significantly more stringent than those for general engineering fabrication.
A286 Fasteners
A286 has a particularly strong industrial connection with high-strength fasteners.
Applications can include:
- Bolts
- Nuts
- Studs
- Screws
- Washers
- Threaded components
The material is attractive for fasteners exposed to elevated temperatures where ordinary stainless-steel fasteners may not provide sufficient strength.
This is why searches such as:
“A286 bolts”
“A286 nuts”
and
“A286 high temperature fasteners”
are commercially relevant.
A286 Bolts, Nuts and Studs
A286 can be used for components where high tensile strength and temperature resistance are required.
Typical applications may include:
- Turbine assemblies
- Exhaust systems
- Engine components
- Aerospace hardware
- Industrial machinery
- High-temperature flanges
For fasteners, the applicable bolting specification should be confirmed because material grade alone does not define the complete fastener requirement.
A286 Shafts and Precision Components
A286 Round Bar can also be machined into components where high strength and corrosion resistance are required.
Potential products include:
- Shafts
- Pins
- Bushes
- Rings
- Spacers
- Machined fittings
- Precision mechanical components
The final component specification should determine whether A286 is appropriate.
A286 Aerospace Applications
A286 has a long association with aerospace and aircraft-engine-related applications.
Possible applications include:
- Engine components
- High-temperature fasteners
- Turbine-related hardware
- Shafts
- Rings
- Structural hardware
Aerospace purchasing normally requires careful attention to the applicable AMS specification and complete material traceability.
A286 Industrial Applications
Outside aerospace, A286 may be considered for:
- Power generation
- Petrochemical equipment
- Industrial turbines
- High-temperature machinery
- Chemical processing equipment
- Heat-related components
- High-strength fasteners
- Precision engineering
The actual suitability depends on temperature, mechanical loading and environmental exposure.
A286 Round Bar Specifications

- PMI testing
- Material Test Certificate
For critical applications, additional third-party inspection may also be requested.
The documentation should correspond to the exact specification ordered.
A286 vs 304 Stainless Steel
A286 and 304 are very different in terms of their primary engineering purpose.
304 stainless steel is widely selected for general corrosion resistance and fabrication.
A286 becomes more attractive when significantly higher strength and elevated-temperature mechanical performance are required.
Therefore, a manufacturer designing a high-strength fastener should not select material solely because both grades are classified as corrosion-resistant alloys.
The operating temperature and mechanical loading need to be considered.
A286 vs 316 Stainless Steel
316 stainless steel provides strong corrosion resistance and is particularly useful in many chloride-containing environments.
A286, meanwhile, is more focused on combining corrosion resistance with high strength and elevated-temperature capability.
If the application is primarily about corrosion resistance, 316 may be appropriate.
If the requirement combines high mechanical strength + elevated temperature + corrosion resistance, A286 may warrant consideration.
A286 vs Inconel
A286 and nickel-based Inconel alloys are both used in demanding environments, but they are not interchangeable.
A286 is an iron-based precipitation-hardening alloy.
Inconel grades are nickel-based alloys developed for more severe high-temperature and corrosion environments.
For example, an application involving extreme oxidation, aggressive chemical exposure or very high temperature may require a nickel-based alloy rather than A286.
The correct selection depends on the service environment rather than the material’s name alone.
A286 Round Bar Price
A286 Round Bar Price can vary substantially based on:
- Diameter
- Quantity
- Specification
- Heat-treatment condition
- Finish
- Certification
- Testing
- Origin
- Stock availability
- Market conditions
A286 is a specialty alloy, so its price should not be compared directly with ordinary stainless-steel round bars.
