Stainless Steel 1.4848 vs CF10M

Stainless Steel · grade comparison

Stainless Steel 1.4848 and CF10M are both stainless steel grades. 1.4848 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 250 MPa (36.3 ksi) for CF10M, about 12% more. In exchange, CF10M is the more ductile: elongation 45% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 160 HB). 1.4848 runs hotter in service (1,100°C vs 650°C continuous) and CF10M conducts electricity better (2.3 % IACS vs 1.9 % IACS). On the shop floor, CF10M machines more easily (fair vs poor) and CF10M welds better (good vs fair).

1.4848Choose it when strength drives the design, or when the part sees heat.

CF10MChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

1.4848 vs CF10M — frequently asked

Is 1.4848 stronger than CF10M?

Yes. 1.4848 has a typical yield strength of 280 MPa (40.6 ksi) against 250 MPa (36.3 ksi) for CF10M — about 12% more. Tensile strength is 530 MPa (76.9 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4848 or CF10M?

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, 1.4848 or CF10M?

CF10M. Its machinability rates fair (40/100) against poor (25/100) for 1.4848; for welding the order is CF10M first (good, 65/100) then 1.4848 (fair, 45/100).
