Stainless Steel S82011 1/4H vs S82011 Annealed

Stainless Steel · S82011 temper comparison

S82011 1/4H and S82011 Annealed are two conditions of the same stainless steel grade, S82011: 1/4H (quarter hard) versus Annealed. The chemistry is identical, so every difference below comes from the condition. S82011 1/4H is the stronger of the two: yield strength 750 MPa (109 ksi) against 520 MPa (75.4 ksi) for S82011 Annealed, about 44% more; tensile strength follows at 900 MPa (131 ksi) vs 700 MPa (102 ksi). In exchange, S82011 Annealed is the more ductile: elongation 32% versus 12% for S82011 1/4H, and S82011 1/4H is harder (290 HB vs 230 HB).
