Stainless Steel 304 vs 316LVM

Stainless Steel · grade comparison

Stainless Steel 304 and 316LVM are both stainless steel grades. 316LVM is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 250 MPa (36.3 ksi) for 304, about 16% more. 304 runs hotter in service (870°C vs 800°C continuous). On the shop floor, 304 machines more easily (45 vs 35 out of 100) and 304 sits in a lower cost tier (standard, $$) than 316LVM (premium, $$$).

304Choose it when the part sees heat, or when the part is machined in volume.

316LVMChoose it when strength drives the design.

304 vs 316LVM — frequently asked

Is 316LVM stronger than 304?

Yes. 316LVM has a typical yield strength of 290 MPa (42.1 ksi) against 250 MPa (36.3 ksi) for 304 — about 16% more. Tensile strength is 590 MPa (85.6 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, 304 or 316LVM?

304 is the lower-cost material: it sits in the standard tier ($$) while 316LVM is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 304 or 316LVM?

304, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for 316LVM.
