Stainless Steel 316H 1/2H vs 316H 1/4H

Stainless Steel · 316H temper comparison

316H 1/2H and 316H 1/4H are two conditions of the same stainless steel grade, 316H: 1/2H (half hard) versus 1/4H (quarter hard). The chemistry is identical, so every difference below comes from the condition. 316H 1/2H is the stronger of the two: yield strength 800 MPa (116 ksi) against 560 MPa (81.2 ksi) for 316H 1/4H, about 43% more; tensile strength follows at 1,070 MPa (155 ksi) vs 900 MPa (131 ksi). In exchange, 316H 1/4H is the more ductile: elongation 12% versus 9% for 316H 1/2H, and 316H 1/2H is harder (310 HB vs 265 HB).

316H 1/2H vs 316H 1/4H — frequently asked

Is 316H 1/2H stronger than 316H 1/4H?

Yes. 316H 1/2H has a typical yield strength of 800 MPa (116 ksi) against 560 MPa (81.2 ksi) for 316H 1/4H — about 43% more. Tensile strength is 1,070 MPa (155 ksi) vs 900 MPa (131 ksi).

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

Annealed is the default 316H 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, 316H 1/2H or 316H 1/4H?

316H 1/4H. Its weldability rates good (65/100) against good (60/100) for 316H 1/2H.
