TECHNICAL INFORMATION FOR A286 PER DMD 0274-22
A286, as per DMD 0274-22 developed by Snecma/Safran, is a stainless steel alloy, iron-nickel-chromium with the addition of molybdenum and titanium. This provides the alloy with exceptional resistance to corrosion as well as high temperatures.
A286 is an austenitic precipitation-hardenable alloy that maintains its strength and structural properties up to 704 degrees Celsius or 1300 degrees Fahrenheit. These are the reasons why A286 is so widely used in the manufacture of high-temperature parts for aerospace turbines and aircraft engine parts.
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.
