Steel 12Cr1MoV vs 60Si2Mn

Steel · grade comparison

Steel 12Cr1MoV and 60Si2Mn are both steel grades. 60Si2Mn is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 285 MPa (41.3 ksi) for 12Cr1MoV, about 68% more; tensile strength follows at 800 MPa (116 ksi) vs 520 MPa (75.4 ksi). In exchange, 12Cr1MoV is the more ductile: elongation 24% versus 15% for 60Si2Mn, and 60Si2Mn is harder (255 HB vs 160 HB). 12Cr1MoV runs hotter in service (580°C vs 200°C continuous). On the shop floor, 12Cr1MoV machines more easily (good vs fair) and 12Cr1MoV welds better (good vs poor).

12Cr1MoV vs 60Si2Mn — frequently asked

Is 60Si2Mn stronger than 12Cr1MoV?

Yes. 60Si2Mn has a typical yield strength of 480 MPa (69.6 ksi) against 285 MPa (41.3 ksi) for 12Cr1MoV — about 68% more. Tensile strength is 800 MPa (116 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 12Cr1MoV or 60Si2Mn?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 12Cr1MoV or 60Si2Mn?

12Cr1MoV. Its machinability rates good (55/100) against fair (45/100) for 60Si2Mn; for welding the order is 12Cr1MoV first (good, 55/100) then 60Si2Mn (poor, 20/100).
