Stainless Steel A286 Annealed vs A286 CW+Aged

Stainless Steel · A286 temper comparison

A286 Annealed and A286 CW+Aged are two conditions of the same stainless steel grade, A286: Annealed versus CW+Aged (cold Worked + Aged). The chemistry is identical, so every difference below comes from the condition. A286 CW+Aged is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 260 MPa (37.7 ksi) for A286 Annealed, about 3.8 times as much; tensile strength follows at 1,240 MPa (180 ksi) vs 620 MPa (89.9 ksi). In exchange, A286 Annealed is the more ductile: elongation 45% versus 12% for A286 CW+Aged, and A286 CW+Aged is harder (360 HB vs 155 HB). On the shop floor, A286 Annealed machines more easily (poor vs not recommended) and A286 Annealed welds better (good vs poor).

A286 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

A286 CW+AgedChoose it when strength drives the design.

A286 Annealed vs A286 CW+Aged — frequently asked

Is A286 CW+Aged stronger than A286 Annealed?

Yes. A286 CW+Aged has a typical yield strength of 1,000 MPa (145 ksi) against 260 MPa (37.7 ksi) for A286 Annealed — about 3.8 times as much. Tensile strength is 1,240 MPa (180 ksi) vs 620 MPa (89.9 ksi).

Which condition does FabDigit quote by default, Annealed or CW+Aged?

Solution Annealed is the default A286 condition in the FabDigit quote flow (neither Annealed nor CW+Aged). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, A286 Annealed or A286 CW+Aged?

A286 Annealed. Its machinability rates poor (28/100) against not recommended (14/100) for A286 CW+Aged; for welding the order is A286 Annealed first (good, 55/100) then A286 CW+Aged (poor, 25/100).
