Stainless Steel CC50 vs HD

Stainless Steel · grade comparison

Stainless Steel CC50 and HD are both stainless steel grades. HD is the stronger of the two: yield strength 345 MPa (50 ksi) against 275 MPa (39.9 ksi) for CC50, about 25% more; tensile strength follows at 585 MPa (84.8 ksi) vs 480 MPa (69.6 ksi). HD is the more ductile: elongation 16% versus 10% for CC50, and CC50 is harder (210 HB vs 190 HB). CC50 conducts electricity better (2.3 % IACS vs 2 % IACS). On the shop floor, CC50 machines more easily (fair vs poor).

CC50Choose it when the part is machined in volume.

HDChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

CC50 vs HD — frequently asked

Is HD stronger than CC50?

Yes. HD has a typical yield strength of 345 MPa (50 ksi) against 275 MPa (39.9 ksi) for CC50 — about 25% more. Tensile strength is 585 MPa (84.8 ksi) vs 480 MPa (69.6 ksi).

Which is cheaper, CC50 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, CC50 or HD?

CC50. Its machinability rates fair (35/100) against poor (25/100) for HD; for welding the order is HD first (fair, 35/100) then CC50 (poor, 30/100).
