Stainless Steel AUS-10 Annealed vs AUS-10 QT58-60

Stainless Steel · AUS-10 temper comparison

AUS-10 Annealed and AUS-10 QT58-60 are two conditions of the same stainless steel grade, AUS-10: Annealed versus QT58-60 (Q&T 58–60 HRC). The chemistry is identical, so every difference below comes from the condition. AUS-10 QT58-60 is the stronger of the two: yield strength 1,900 MPa (276 ksi) against 450 MPa (65.3 ksi) for AUS-10 Annealed, about 4.2 times as much; tensile strength follows at 2,050 MPa (297 ksi) vs 760 MPa (110 ksi). In exchange, AUS-10 Annealed is the more ductile: elongation 13% versus 2% for AUS-10 QT58-60, and AUS-10 QT58-60 is harder (59 HRC vs 22 HRC). AUS-10 Annealed runs hotter in service (500°C vs 350°C continuous). On the shop floor, AUS-10 Annealed machines more easily (fair vs not recommended).
