Stainless Steel 1.4837 vs CF8

Stainless Steel · grade comparison

Stainless Steel 1.4837 and CF8 are both stainless steel grades. Both yield at about 265 MPa — strength does not separate them. CF8 is the more ductile: elongation 55% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 140 HB). CF8 is stiffer (195 GPa vs 185 GPa) and 1.4837 runs hotter in service (1,050°C vs 760°C continuous). On the shop floor, CF8 machines more easily (fair vs poor) and CF8 welds better (very good vs fair).

1.4837 vs CF8 — frequently asked

What is the difference between 1.4837 and CF8?

Stainless Steel 1.4837 and CF8 are both stainless steel grades. Both yield at about 265 MPa — strength does not separate them. CF8 is the more ductile: elongation 55% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 140 HB).

Which is cheaper, 1.4837 or CF8?

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, 1.4837 or CF8?

CF8. Its machinability rates fair (40/100) against poor (22/100) for 1.4837; for welding the order is CF8 first (very good, 78/100) then 1.4837 (fair, 40/100).
