Stainless Steel 1.4710 vs HD

Stainless Steel · grade comparison

Stainless Steel 1.4710 and HD are both stainless steel grades. HD is the stronger of the two: yield strength 345 MPa (50 ksi) against 290 MPa (42.1 ksi) for 1.4710, about 19% more; tensile strength follows at 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi). HD is the more ductile: elongation 16% versus 6% for 1.4710, and 1.4710 is harder (205 HB vs 190 HB). HD runs hotter in service (1,090°C vs 850°C continuous) and 1.4710 conducts heat better (26 W/m·K vs 19 W/m·K). On the shop floor, 1.4710 machines more easily (fair vs poor).

1.4710 vs HD — frequently asked

Is HD stronger than 1.4710?

Yes. HD has a typical yield strength of 345 MPa (50 ksi) against 290 MPa (42.1 ksi) for 1.4710 — about 19% more. Tensile strength is 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4710 or HD?

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, 1.4710 or HD?

1.4710. Its machinability rates fair (40/100) against poor (25/100) for HD; for welding the order is HD first (fair, 35/100) then 1.4710 (poor, 30/100).
