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

Stainless Steel · 316LVM temper comparison

316LVM-1/4 Hard and 316LVM Full Hard are two conditions of the same stainless steel grade, 316LVM: 1/4 Hard (quarter hard) versus Full Hard. The chemistry is identical, so every difference below comes from the condition. 316LVM Full Hard is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 520 MPa (75.4 ksi) for 316LVM-1/4 Hard, about 112% more; tensile strength follows at 1,250 MPa (181 ksi) vs 760 MPa (110 ksi). In exchange, 316LVM-1/4 Hard is the more ductile: elongation 28% versus 6% for 316LVM Full Hard, and 316LVM Full Hard is harder (375 HB vs 245 HB). 316LVM-1/4 Hard runs hotter in service (300°C vs 250°C continuous). On the shop floor, 316LVM-1/4 Hard welds better (very good vs good).

316LVM-1/4 HardChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

316LVM Full HardChoose it when strength drives the design.

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

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

Yes. 316LVM Full Hard has a typical yield strength of 1,100 MPa (160 ksi) against 520 MPa (75.4 ksi) for 316LVM-1/4 Hard — about 112% more. Tensile strength is 1,250 MPa (181 ksi) vs 760 MPa (110 ksi).

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

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

316LVM Full 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 Full Hard (good, 55/100).
