What Is UNS S66286?
UNS S66286 is the Unified Numbering System designation associated with A286.
When searching for the material online, industrial buyers may use several different terms:
A286
Alloy A286
UNS S66286
UNS S66286 Round Bar
A286 Stainless Steel
A286 Nickel-Iron-Chromium Alloy
These terms can therefore be important when building a searchable technical product page.
However, the exact applicable specification should always be confirmed before purchasing.
What Is Werkstoff 1.4980?
Werkstoff 1.4980 is a designation commonly associated with A286.
Therefore, buyers searching for:
1.4980 Round Bar
1.4980 Material
1.4980 Alloy
may be looking for the same general A286 material family.
When preparing an enquiry, it is useful to provide both the commercial designation and the applicable standard.
For example:
A286 / UNS S66286 / 1.4980 / Round Bar
This makes the requirement considerably clearer to a supplier.
Is A286 Stainless Steel or Nickel Alloy?
A286 is often described as a precipitation-hardening stainless steel or an iron-nickel-chromium alloy.
It contains substantial nickel and chromium, together with other alloying elements that allow precipitation hardening.
Its classification can therefore appear differently depending on the technical reference or industry context.
For procurement purposes, the most important identifiers are:
A286 + UNS S66286 + applicable specification
rather than relying solely on the generic term “stainless steel.”
Why Is A286 Used in High-Temperature Applications?
A286 is selected when an engineering component needs more than ordinary corrosion resistance.
The material provides a combination of:
- High strength
- Corrosion resistance
- Elevated-temperature capability
- Good oxidation resistance
- Good fatigue performance
- Useful creep resistance
- Precipitation-hardening capability
This makes it relevant to applications where a component may experience:
High Temperature + Mechanical Stress + Corrosive Environment
The actual service temperature and loading conditions should always be checked against the design requirements.
A286 Chemical Composition
Typical A286 composition includes:
| Element | Typical / Specification Range |
|---|---|
| Iron | Balance |
| Nickel | 24.0–27.0% |
| Chromium | 13.5–16.0% |
| Molybdenum | 1.0–1.5% |
| Titanium | 1.9–2.35% |
| Aluminium | 0.35% max. |
| Carbon | 0.08% max. |
| Manganese | 2.0% max. |
| Silicon | 1.0% max. |
| Vanadium | 0.10–0.50% |
| Boron | Controlled addition |
Exact limits depend on the applicable specification.
For critical industrial procurement, the chemistry should always be checked against the supplied Material Test Certificate.
A286 Mechanical Properties
A286 mechanical properties vary significantly according to the material condition.
Important properties include:
- Tensile strength
- Yield strength
- Elongation
- Hardness
- Fatigue strength
- Creep resistance
- Stress-rupture performance
This is particularly important with A286 because the alloy can be supplied in different heat-treatment conditions.
A buyer should therefore specify the required condition rather than simply requesting:
“A286 Round Bar.”
A286 Tensile Strength and Yield Strength
A286 can achieve substantially higher strength through precipitation hardening.
The actual tensile and yield strength depend on:
- Solution treatment
- Aging treatment
- Section size
- Product form
- Applicable specification
For this reason, generic strength values found online should not be treated as the acceptance criteria for a purchase.
If the component drawing requires a specific tensile strength or hardness range, that requirement should be included directly in the enquiry.
A286 Corrosion Resistance
A286 provides useful corrosion resistance in many industrial environments.
Its chromium content contributes to corrosion and oxidation resistance, while the nickel content supports its performance in elevated-temperature service.
The alloy can be used in environments involving:
- Atmospheric exposure
- Elevated temperatures
- Industrial gases
- Petrochemical service
- Power-generation equipment
- Aerospace environments
However, corrosion resistance depends on the specific operating environment.
Temperature, chemicals, chlorides, stress and exposure time should all be considered.
A286 High-Temperature Strength
One of the major reasons for selecting A286 is its ability to maintain useful strength at elevated temperatures.
This makes it attractive for:
- Turbine components
- High-temperature fasteners
- Engine components
- Springs
- Power-generation equipment
- Aerospace hardware
A286 is particularly useful where the component must maintain mechanical integrity rather than simply survive exposure to heat.
A286 Creep and Stress-Rupture Performance
Components operating at elevated temperatures for long periods can experience creep.
Creep is gradual deformation under sustained stress.
This is important for:
- Turbines
- Power-generation systems
- High-temperature fasteners
- Pressure equipment
- Aerospace components
A286 can be considered for applications where resistance to creep and stress rupture is required.
The actual design temperature and stress should be evaluated before material selection.
A286 Heat Treatment
Heat treatment is one of the most important aspects of A286 procurement.
The material can be processed through:
Solution Treatment → Cooling → Aging / Precipitation Hardening
The exact treatment depends on the applicable specification and required properties.
Heat treatment controls the precipitation of strengthening phases and therefore affects the final mechanical properties.
A286 Solution Annealing
Solution treatment is used to establish an appropriate metallurgical condition before aging.
The exact temperature, holding time and cooling method should follow the applicable material specification.
After solution treatment, the material may undergo precipitation-hardening treatment to achieve the required strength.
For critical components, the supplier should provide appropriate heat-treatment documentation where required.
A286 Precipitation Hardening
Precipitation hardening is the process that allows A286 to develop significantly higher strength.
The material is first solution treated and then aged under controlled conditions.
The resulting microstructure provides increased strength compared with the solution-treated condition.
This is why the words:
A286 + Heat Treatment Condition
are particularly important when purchasing the material.
A286 Age Hardening
Age hardening is another term commonly used for precipitation hardening.
The process is carefully controlled because over-aging or incorrect processing can alter the desired mechanical properties.
For industrial procurement, buyers should identify the required material condition from the applicable specification or engineering drawing.

The chemical environment should be evaluated before selecting the alloy.
A286 Machining
A286 can be machined, but machining conditions depend strongly on the material condition.
Precipitation-hardened material can be considerably more difficult to machine than conventional mild steel.
Machining teams should consider:
- Cutting speed
- Feed rate
- Tool geometry
- Tool material
- Coolant
- Workpiece rigidity
- Material hardness
If machining is required after aging, the machining strategy should account for the higher strength and hardness.
A286 Welding
