Stainless Steel 316LVM-1/2 Hard vs 316LVM-1/4 Hard

Stainless Steel · 316LVM temper comparison

316LVM-1/2 Hard and 316LVM-1/4 Hard are two conditions of the same stainless steel grade, 316LVM: 1/2 Hard (half hard) versus 1/4 Hard (quarter hard). The chemistry is identical, so every difference below comes from the condition. 316LVM-1/2 Hard is the stronger of the two: yield strength 830 MPa (120 ksi) against 520 MPa (75.4 ksi) for 316LVM-1/4 Hard, about 60% more; tensile strength follows at 1,000 MPa (145 ksi) vs 760 MPa (110 ksi). In exchange, 316LVM-1/4 Hard is the more ductile: elongation 28% versus 14% for 316LVM-1/2 Hard, and 316LVM-1/2 Hard is harder (300 HB vs 245 HB). On the shop floor, 316LVM-1/4 Hard welds better (very good vs good).

316LVM-1/2 Hard vs 316LVM-1/4 Hard — frequently asked

Is 316LVM-1/2 Hard stronger than 316LVM-1/4 Hard?

Yes. 316LVM-1/2 Hard has a typical yield strength of 830 MPa (120 ksi) against 520 MPa (75.4 ksi) for 316LVM-1/4 Hard — about 60% more. Tensile strength is 1,000 MPa (145 ksi) vs 760 MPa (110 ksi).

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

Annealed is the default 316LVM condition in the FabDigit quote flow (neither 1/2 Hard nor 1/4 Hard). 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, 316LVM-1/2 Hard or 316LVM-1/4 Hard?

316LVM-1/2 Hard, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 316LVM-1/4 Hard; for welding the order is 316LVM-1/4 Hard first (very good, 75/100) then 316LVM-1/2 Hard (good, 65/100).
