Stainless Steel 330 vs S32053

Stainless Steel · grade comparison

Stainless Steel 330 and S32053 are both stainless steel grades. S32053 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 270 MPa (39.2 ksi) for 330, about 41% more; tensile strength follows at 750 MPa (109 ksi) vs 585 MPa (84.8 ksi). S32053 is harder — 200 HB against 150 HB for 330 — which matters for wear surfaces and threads. 330 runs hotter in service (1,150°C vs 425°C continuous). On the shop floor, S32053 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).

330 vs S32053 — frequently asked

Is S32053 stronger than 330?

Yes. S32053 has a typical yield strength of 380 MPa (55.1 ksi) against 270 MPa (39.2 ksi) for 330 — about 41% more. Tensile strength is 750 MPa (109 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, 330 or S32053?

S32053 is the lower-cost material: it sits in the high tier ($$$$) while 330 is specialty ($$$$$). 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, 330 or S32053?

330, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for S32053; for welding the order is S32053 first (very good, 70/100) then 330 (good, 62/100).
