Stainless Steel 316LVM-1/2 Hard vs 316LVM Annealed
Stainless Steel · 316LVM temper comparison
316LVM-1/2 Hard and 316LVM Annealed are two conditions of the same stainless steel grade, 316LVM: 1/2 Hard (half hard) versus Annealed. 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 290 MPa (42.1 ksi) for 316LVM Annealed, about 186% more; tensile strength follows at 1,000 MPa (145 ksi) vs 590 MPa (85.6 ksi). In exchange, 316LVM Annealed is the more ductile: elongation 55% versus 14% for 316LVM-1/2 Hard, and 316LVM-1/2 Hard is harder (300 HB vs 150 HB). 316LVM Annealed runs hotter in service (800°C vs 300°C continuous). On the shop floor, 316LVM-1/2 Hard machines more easily (45 vs 35 out of 100) and 316LVM Annealed welds better (excellent vs good).

316LVM AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
316LVM-1/2 Hard vs 316LVM Annealed: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

316LVM-1/2 Hard vs 316LVM Annealed — frequently asked
Is 316LVM-1/2 Hard stronger than 316LVM Annealed?
Yes. 316LVM-1/2 Hard has a typical yield strength of 830 MPa (120 ksi) against 290 MPa (42.1 ksi) for 316LVM Annealed — about 186% more. Tensile strength is 1,000 MPa (145 ksi) vs 590 MPa (85.6 ksi).
Which condition does FabDigit quote by default, 1/2 Hard or Annealed?
Annealed is the default 316LVM condition in the FabDigit quote flow. 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 Annealed?
316LVM-1/2 Hard, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for 316LVM Annealed; for welding the order is 316LVM Annealed first (excellent, 85/100) then 316LVM-1/2 Hard (good, 65/100).
