Stainless Steel AUS-10-CR vs AUS-10 QT60-62-CRYO

Stainless Steel · AUS-10 temper comparison

AUS-10-CR and AUS-10 QT60-62-CRYO are two conditions of the same stainless steel grade, AUS-10: CR (cold rolled) versus QT60-62-CRYO (Q&T 60–62 HRC). The chemistry is identical, so every difference below comes from the condition. AUS-10 QT60-62-CRYO is the stronger of the two: yield strength 2,000 MPa (290 ksi) against 780 MPa (113 ksi) for AUS-10-CR, about 156% more; tensile strength follows at 2,150 MPa (312 ksi) vs 950 MPa (138 ksi). In exchange, AUS-10-CR is the more ductile: elongation 6% versus 1.5% for AUS-10 QT60-62-CRYO, and AUS-10-CR is harder (285 HB vs 240 HB). AUS-10-CR runs hotter in service (300°C vs 250°C continuous). On the shop floor, AUS-10-CR machines more easily (poor vs not recommended).

AUS-10-CR vs AUS-10 QT60-62-CRYO — frequently asked

Is AUS-10 QT60-62-CRYO stronger than AUS-10-CR?

Yes. AUS-10 QT60-62-CRYO has a typical yield strength of 2,000 MPa (290 ksi) against 780 MPa (113 ksi) for AUS-10-CR — about 156% more. Tensile strength is 2,150 MPa (312 ksi) vs 950 MPa (138 ksi).

Which condition does FabDigit quote by default, CR or QT60-62-CRYO?

Annealed is the default AUS-10 condition in the FabDigit quote flow (neither CR nor QT60-62-CRYO). 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, AUS-10-CR or AUS-10 QT60-62-CRYO?

AUS-10-CR. Its machinability rates poor (30/100) against not recommended (8/100) for AUS-10 QT60-62-CRYO; for welding the order is AUS-10 QT60-62-CRYO first (poor, 25/100) then AUS-10-CR (poor, 20/100).
