SAE J467 — A286 Special Purpose Alloy Designation
SAE J467 is the SAE International standard for commercial-name alloy designations covering wrought stainless and heat-resistant steels. A286 is included in SAE J467 as a Special Purpose Alloy designation alongside other common iron-nickel-chromium and nickel-base superalloys. The SAE J467 entry for A286 references UNS S66286 as the underlying chemistry. Used as the SAE common-name reference on drawings citing the A286 designation. See parent A286 AMS / ASTM specifications hub, related UNS S66286, A286 equivalent grades cross-reference.
Spec Scope & Coverage
SAE J467 covers commercial-name designations for wrought stainless and heat-resistant steels. The A286 designation in SAE J467 references UNS S66286 chemistry plus the standard solution-treated and precipitation-aged condition. SAE J467 is a designation-reference standard rather than a material-property spec — for actual mechanical and chemical property requirements, the subsidiary specs (AMS 5731-5895, ASTM A453 grade 660, ASTM A638 grade 660) are referenced.
A286 Chemical Composition (UNS S66286)
| Element | Min % | Max % | Notes |
|---|---|---|---|
| Iron (Fe) | Balance | Balance | ~53 % typical |
| Nickel (Ni) | 24.0 | 27.0 | Solid-solution stabilizer |
| Chromium (Cr) | 13.5 | 16.0 | Corrosion + oxidation resistance |
| Titanium (Ti) | 1.90 | 2.35 | Gamma-prime former (Ni3Ti) |
| Molybdenum (Mo) | 1.00 | 1.50 | Solid-solution strengthener |
| Vanadium (V) | 0.10 | 0.50 | Carbide stabilizer |
| Aluminium (Al) | 0 | 0.35 | Gamma-prime former (Ni3Al) |
| Boron (B) | 0.001 | 0.010 | Grain-boundary strengthening |
| Carbon (C) | 0 | 0.08 | Per ASTM A453 |

When to Specify SAE J467 — A286 Special Purpose Alloy Designation
- Drawing reference (common name): SAE J467 is cited on US-spec drawings for material designation cross-reference. Modern drawings increasingly cite UNS S66286 directly.
- Material identification only: SAE J467 does NOT specify mechanical property minima or heat-treatment — for actual property requirements, cite the subsidiary spec (AMS 5731-5895, ASTM A453, ASTM A638).
- Cross-reference reference: See A286 equivalent grades cross-reference for the complete designation map.
- Material-property specs: For actual property + heat-treatment requirements, cite AMS 5732 (aerospace bar) or ASTM A453 grade 660 (industrial bolting).

SAE J467 — A286 Special Purpose Alloy Designation — Frequently Asked Questions
What is SAE J467?
SAE International standard for commercial-name alloy designations covering wrought stainless and heat-resistant steels. A286 is included as a Special Purpose Alloy designation referencing UNS S66286 chemistry.
Is SAE J467 a property spec?
NO — SAE J467 is a designation-reference standard. It does not specify mechanical property minima or heat-treatment requirements. For actual property requirements, the subsidiary spec (AMS 5731-5895, ASTM A453, ASTM A638) must be cited separately.
How does SAE J467 relate to UNS S66286?
SAE J467 A286 references UNS S66286 chemistry. Both are material identifiers — UNS S66286 is the universal Unified Numbering System designation; SAE J467 A286 is the SAE common-name designation. Identical chemistry.
Should I cite SAE J467 or UNS S66286 on drawings?
Cite UNS S66286 — universal SAE/ASTM material identifier. SAE J467 A286 is a legacy common-name reference; modern drawings increasingly cite UNS S66286 directly. Combine with applicable subsidiary spec (AMS 5732, ASTM A453, etc.) for property requirements.
Is SAE J467 deprecated?
Not deprecated, but increasingly secondary to UNS S66286. SAE J467 is still cited on legacy US-spec drawings as material designation cross-reference.
What other A286 designations exist?
Iron Alloy 660, Alloy 660, AISI 660, UNS S66286, DIN 1.4980, X5NiCrTiMoVB25-15-2, Incoloy® A286, Pyromet® A286, ATI A286™, Tinidur®. See A286 equivalent grades cross-reference.
Can SAE J467 be cited on European drawings?
Yes for designation reference but European drawings typically cite DIN 1.4980 / X5NiCrTiMoVB25-15-2 instead. Multiple designations can co-exist on a single drawing.
What's the lead time on SAE J467 A286 material?
Same as the underlying subsidiary spec — typically 4-6 weeks for AMS 5732 standard sizes; 6-10 weeks for larger forgings. SAE J467 designation alone does not affect lead time.
Is SAE J467 A286 magnetic?
No. Magnetic permeability < 1.005 verified per ASTM A342 on aerospace lots.
