Stainless Steel 1.4107 vs HC

Stainless Steel · grade comparison

Stainless Steel 1.4107 and HC are both stainless steel grades. HC is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 400 MPa (58 ksi) for 1.4107, about 13% more; tensile strength follows at 690 MPa (100 ksi) vs 610 MPa (88.5 ksi). In exchange, 1.4107 is the more ductile: elongation 22% versus 12% for HC, and HC is harder (205 HB vs 185 HB). 1.4107 is stiffer (215 GPa vs 200 GPa) and HC runs hotter in service (1,090°C vs 400°C continuous). On the shop floor, 1.4107 machines more easily (fair vs poor) and 1.4107 welds better (very good vs poor).

1.4107 vs HC — frequently asked

Is HC stronger than 1.4107?

Yes. HC has a typical yield strength of 450 MPa (65.3 ksi) against 400 MPa (58 ksi) for 1.4107 — about 13% more. Tensile strength is 690 MPa (100 ksi) vs 610 MPa (88.5 ksi).

Which is cheaper, 1.4107 or HC?

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, 1.4107 or HC?

1.4107. Its machinability rates fair (45/100) against poor (32/100) for HC; for welding the order is 1.4107 first (very good, 70/100) then HC (poor, 30/100).
