Stainless Steel 304L vs 316LVM
Stainless Steel · grade comparison
Stainless Steel 304L and 316LVM are both stainless steel grades. 316LVM is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 275 MPa (39.9 ksi) for 304L, about 5% more. 316LVM runs hotter in service (800°C vs 425°C continuous).

304L vs 316LVM: 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.

304L vs 316LVM — frequently asked
Is 316LVM stronger than 304L?
Yes. 316LVM has a typical yield strength of 290 MPa (42.1 ksi) against 275 MPa (39.9 ksi) for 304L — about 5% more. Tensile strength is 590 MPa (85.6 ksi) vs 585 MPa (84.8 ksi).
Which is cheaper, 304L or 316LVM?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 304L or 316LVM?
304L, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 316LVM; for welding the order is 304L first (excellent, 92/100) then 316LVM (excellent, 85/100).
