Stainless Steel E410 vs ER308H

Stainless Steel · grade comparison

Stainless Steel E410 and ER308H are both stainless steel grades. ER308H is the stronger of the two: tensile strength 590 MPa (85.6 ksi) against 560 MPa (81.2 ksi) for E410, about 5% more. ER308H is the more ductile: elongation 38% versus 23% for E410, and E410 is harder (200 HB vs 175 HB). ER308H runs hotter in service (800°C vs 650°C continuous) and E410 conducts heat better (24.9 W/m·K vs 16.2 W/m·K). On the shop floor, ER308H welds better (excellent vs fair).

E410 vs ER308H — frequently asked

Is ER308H stronger than E410?

Yes. ER308H has a typical tensile strength of 590 MPa (85.6 ksi) against 560 MPa (81.2 ksi) for E410 — about 5% more.

Which is cheaper, E410 or ER308H?

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, E410 or ER308H?

E410, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for ER308H; for welding the order is ER308H first (excellent, 88/100) then E410 (fair, 40/100).
