Stainless Steel 301 vs S24000

Stainless Steel · grade comparison

Stainless Steel 301 and S24000 are both stainless steel grades. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 400 MPa (58 ksi) for S24000, about 43% more; tensile strength follows at 900 MPa (131 ksi) vs 724 MPa (105 ksi). In exchange, S24000 is the more ductile: elongation 50% versus 25% for 301, and 301 is harder (270 HB vs 200 HB). S24000 runs hotter in service (760°C vs 425°C continuous) and 301 conducts heat better (16.2 W/m·K vs 12.5 W/m·K).

301Choose it when strength drives the design.

S24000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

301 vs S24000 — frequently asked

Is 301 stronger than S24000?

Yes. 301 has a typical yield strength of 570 MPa (82.7 ksi) against 400 MPa (58 ksi) for S24000 — about 43% more. Tensile strength is 900 MPa (131 ksi) vs 724 MPa (105 ksi).

Which is cheaper, 301 or S24000?

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, 301 or S24000?

301. Its machinability rates fair (35/100) against poor (30/100) for S24000; for welding the order is S24000 first (very good, 70/100) then 301 (good, 65/100).
