Stainless Steel 1.4762 vs 405

Stainless Steel · grade comparison

Stainless Steel 1.4762 and 405 are both stainless steel grades. 1.4762 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 280 MPa (40.6 ksi) for 405, about 18% more; tensile strength follows at 580 MPa (84.1 ksi) vs 480 MPa (69.6 ksi). In exchange, 405 is the more ductile: elongation 28% versus 18% for 1.4762, and 1.4762 is harder (195 HB vs 155 HB). 1.4762 is lighter (7.15 g/cm³ vs 7.75 g/cm³ for 405) and 1.4762 runs hotter in service (1,150°C vs 705°C continuous). On the shop floor, 405 machines more easily (good vs fair) and 405 welds better (very good vs fair).

1.4762Choose it when strength drives the design, or when weight is the constraint.

405Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

1.4762 vs 405 — frequently asked

Is 1.4762 stronger than 405?

Yes. 1.4762 has a typical yield strength of 330 MPa (47.9 ksi) against 280 MPa (40.6 ksi) for 405 — about 18% more. Tensile strength is 580 MPa (84.1 ksi) vs 480 MPa (69.6 ksi).

Which is cheaper, 1.4762 or 405?

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, 1.4762 or 405?

405. Its machinability rates good (55/100) against fair (40/100) for 1.4762; for welding the order is 405 first (very good, 70/100) then 1.4762 (fair, 35/100).
