Common A286 Alloy Specifications & Heat Treatment
| Grade | A286 Alloy |
|---|---|
| Common bar standards | ASTM A638 iron-nickel alloy bar; AMS 5731/5732/5737 can apply to specified certified A286 conditions. |
| Heat treatment / supply condition | Solution-treated and precipitation aged according to required certified condition. |
| Precision finishing | Specify finished OD and limits, rod length and quantity, straightness, roughness, hardness, and required documents. |
Exact age treatment and aerospace certification must be agreed before purchase.
Typical standards and conditions are purchasing references only, not a stock/certification or in-house heat-treat promise. Confirm supplied product form, condition and any externally coordinated thermal treatment in the written RFQ.
IRON-NICKEL-CHROMIUM SUPERALLOY • MATERIAL GRADE BUYING GUIDE
A286 Alloy precision ground rod stock — A286 is a precipitation-strengthening iron-nickel-chromium alloy often selected for qualified high-temperature mechanical hardware.
A286 Alloy Rod Material and Specification
For this grade, the important question is not simply whether a rod is offered as “precision ground.” Buyers should define the material identity, the intended delivery condition and the acceptance requirements. Specify UNS S66286 and any AMS or ASTM bar standard called out by engineering.
Condition and Processing Considerations
Require the correct solution-treated/aged condition and mechanical property certification.
Where A286 Alloy Rod Stock May Be Considered
Aerospace fasteners, turbine-adjacent parts and other high-temperature precision components.
The required rod diameter and finish must be consistent with the final manufacturing process. Ground stock may be appropriate for selected machining or shaft-preparation workflows, but the final component design determines whether the grade, microstructure and surface condition are suitable.
A286 Alloy Centerless Ground & TG&P Bar Options
A286 Alloy Centerless Ground Bar
For A286 Alloy centerless ground rod or bar, the required iron-nickel alloy material standard and precipitation-aging condition govern OD grinding and final strength requirements. See centerless grinding services for OD processing requirements.
A286 Alloy TG&P / Turned, Ground & Polished
For A286 Alloy TG&P (TGP) or turned, ground and polished bar, a TG&P order for A286 must specify its exact condition, finished shaft tolerance and full turning/polishing route; feasibility is confirmed by quotation. Review material sourcing and polishing.
Centerless-ground and TG&P stock are different processing specifications. Confirm grade, supplied condition, OD limits, surface finish, straightness, process sequencing and availability in a written quotation. Request pricing →
What to Verify Before Ordering
Any substitution or change to thermal processing requires formal approval where regulated requirements apply.
- Finished outside diameter: state the size and exact upper/lower OD limits, not just a nominal inch or millimeter dimension.
- Lengths and quantity: give the bar length or cut length, end requirements, number of pieces and requested shipment schedule.
- Material condition: include the specified grade, applicable product standard, heat-treatment or hardness state and certification requirements.
- Inspection: specify straightness with a measurement span, roundness, surface roughness and traceability where your application calls for them.
Supply, OD Grinding and Quote Requirements
Precision Ground Rods provides grade-specific sourcing and precision bar processing quotations. Depending on the grade, condition, diameter and length, material supply may be combined with outside-diameter grinding, straightening, polishing, cutting and packaging. These capabilities are evaluated for each RFQ; this page does not promise a standard stocked size or a universal grinder tolerance.
For a useful A286 Alloy inquiry, attach the purchase specification and drawing and indicate whether you need finished ground rod stock or want customer-owned stock processed. Include the quantity, delivery destination and inspection plan so the quotation can address all relevant requirements.
Browse all rod material grades to compare other chemistries and product forms. Verify any material substitution with engineering.
General purchasing information, not a certified material test report or an approval for regulated service. All material properties, dimensions and certificates must be confirmed in the written quotation.
