Stainless Steel S21460 1/2H vs S21460 1/4H

Stainless Steel · S21460 temper comparison

S21460 1/2H and S21460 1/4H are two conditions of the same stainless steel grade, S21460: 1/2H (half hard) versus 1/4H (quarter hard). The chemistry is identical, so every difference below comes from the condition. S21460 1/2H is the stronger of the two: yield strength 830 MPa (120 ksi) against 620 MPa (89.9 ksi) for S21460 1/4H, about 34% more; tensile strength follows at 1,080 MPa (157 ksi) vs 930 MPa (135 ksi). In exchange, S21460 1/4H is the more ductile: elongation 25% versus 12% for S21460 1/2H, and S21460 1/2H is harder (300 HB vs 250 HB). S21460 1/4H runs hotter in service (480°C vs 425°C continuous).

S21460 1/2H vs S21460 1/4H — frequently asked

Is S21460 1/2H stronger than S21460 1/4H?

Yes. S21460 1/2H has a typical yield strength of 830 MPa (120 ksi) against 620 MPa (89.9 ksi) for S21460 1/4H — about 34% more. Tensile strength is 1,080 MPa (157 ksi) vs 930 MPa (135 ksi).

Which condition does FabDigit quote by default, 1/2H or 1/4H?

A is the default S21460 condition in the FabDigit quote flow (neither 1/2H nor 1/4H). 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 welds better, S21460 1/2H or S21460 1/4H?

S21460 1/4H. Its weldability rates fair (50/100) against fair (45/100) for S21460 1/2H.
