TECHNICAL INFORMATION FOR A286 PER MSRR 6532
MSRR 6532, is a Rolls-Royce specification for A286 stainless steel, an iron-nickel-chromium alloy resistant to corrosion and heat. It also receives enhanced strength and oxidation resistance with the addition of molybdenum and titanium, particularly at high temperatures.
A286, as per specification in MSRR 6532, is an austenitic precipitation hardenable alloy that maintains reliable mechanical performance up to 1300 °F (704 °C). It is commonly used in aircraft engines and turbines, where it is subjected to the most extreme demands in terms of durability and heat resistance.
Is A286 a Stainless Steel?
Some companies list A286 under Nickel and some companies list A286 under Stainless Steel. Ultimately, It is an iron-nickel-chromium alloy with additions of molybdenum and titanium making it a super alloy that is in between those categories. As one of the austenitic alloys it maintains good strength and oxidation resistance at temperatures up to 1300ºF. Due to its high strength and excellent fabrication characteristics it performs like a Nickel alloy but has a similar density to that of Stainless Steel. Because of these characteristics, A286 is one of the most popular high temperature alloys.
Rolls Royce specification MSRR 6532
As a Tier 1 Aerospace company, Boeing holds its subcontractors to the same standards by ensuring they source material per MSRR 6532 from approved sources. This creates accountability and ensures the highest quality standards are achieved in the manufacturing process. SABRe (Supplier Management System Requirements) is the supplier-facing element of the Rolls-Royce Management System and is applicable to all suppliers or partners who supply products and / or services to Rolls-Royce contracts / purchase orders.
