Stainless Steel 410 vs SUH1

Stainless Steel · grade comparison

Stainless Steel 410 and SUH1 are both stainless steel grades. SUH1 is the stronger of the two: yield strength 760 MPa (110 ksi) against 310 MPa (45 ksi) for 410, about 145% more; tensile strength follows at 1,000 MPa (145 ksi) vs 517 MPa (75 ksi). In exchange, 410 is the more ductile: elongation 25% versus 18% for SUH1, and SUH1 is harder (295 HB vs 155 HB). SUH1 is stiffer (215 GPa vs 200 GPa) and SUH1 runs hotter in service (750°C vs 650°C continuous). On the shop floor, 410 machines more easily (good vs fair), 410 welds better (fair vs poor), and SUH1 sits in a lower cost tier (standard, $$) than 410 (premium, $$$).

410Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

SUH1Choose it when strength drives the design, or when the part sees heat.

410 vs SUH1 — frequently asked

Is SUH1 stronger than 410?

Yes. SUH1 has a typical yield strength of 760 MPa (110 ksi) against 310 MPa (45 ksi) for 410 — about 145% more. Tensile strength is 1,000 MPa (145 ksi) vs 517 MPa (75 ksi).

Which is cheaper, 410 or SUH1?

SUH1 is the lower-cost material: it sits in the standard tier ($$) while 410 is premium ($$$). 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, 410 or SUH1?

410. Its machinability rates good (55/100) against fair (35/100) for SUH1; for welding the order is 410 first (fair, 45/100) then SUH1 (poor, 22/100).
