Stainless Steel S28200 1/2H vs S28200 1/4H

Stainless Steel · S28200 temper comparison

S28200 1/2H and S28200 1/4H are two conditions of the same stainless steel grade, S28200: 1/2H (half hard) versus 1/4H (quarter hard). The chemistry is identical, so every difference below comes from the condition. S28200 1/2H is the stronger of the two: yield strength 760 MPa (110 ksi) against 585 MPa (84.8 ksi) for S28200 1/4H, about 30% more; tensile strength follows at 1,030 MPa (149 ksi) vs 860 MPa (125 ksi). In exchange, S28200 1/4H is the more ductile: elongation 32% versus 18% for S28200 1/2H, and S28200 1/2H is harder (310 HB vs 250 HB).

S28200 1/2HChoose it when strength drives the design.

S28200 1/4HChoose it when the part is bent, formed or impact-loaded.

S28200 1/2H vs S28200 1/4H — frequently asked

Is S28200 1/2H stronger than S28200 1/4H?

Yes. S28200 1/2H has a typical yield strength of 760 MPa (110 ksi) against 585 MPa (84.8 ksi) for S28200 1/4H — about 30% more. Tensile strength is 1,030 MPa (149 ksi) vs 860 MPa (125 ksi).

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

Annealed is the default S28200 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 is easier to machine, S28200 1/2H or S28200 1/4H?

S28200 1/4H, by a small margin. Both rate poor for machinability — 32/100 against 26/100 for S28200 1/2H; for welding the order is S28200 1/4H first (fair, 50/100) then S28200 1/2H (fair, 45/100).
