Steel 13MoCrNi42-16-14-N vs 13MoCrNi42-16-14 VIM-VAR

Steel · 13MoCrNi42-16-14 temper comparison

13MoCrNi42-16-14-N and 13MoCrNi42-16-14 VIM-VAR are two conditions of the same steel grade, 13MoCrNi42-16-14: N (normalized) versus VIM-VAR (vacuum induction melted + vacuum arc remelted). The chemistry is identical, so every difference below comes from the condition. 13MoCrNi42-16-14-N is the stronger of the two: yield strength 850 MPa (123 ksi) against 580 MPa (84.1 ksi) for 13MoCrNi42-16-14 VIM-VAR, about 47% more; tensile strength follows at 1,150 MPa (167 ksi) vs 880 MPa (128 ksi). In exchange, 13MoCrNi42-16-14 VIM-VAR is the more ductile: elongation 20% versus 13% for 13MoCrNi42-16-14-N, and 13MoCrNi42-16-14-N is harder (330 HB vs 220 HB). On the shop floor, 13MoCrNi42-16-14 VIM-VAR machines more easily (30 vs 20 out of 100).

13MoCrNi42-16-14-N vs 13MoCrNi42-16-14 VIM-VAR — frequently asked

Is 13MoCrNi42-16-14-N stronger than 13MoCrNi42-16-14 VIM-VAR?

Yes. 13MoCrNi42-16-14-N has a typical yield strength of 850 MPa (123 ksi) against 580 MPa (84.1 ksi) for 13MoCrNi42-16-14 VIM-VAR — about 47% more. Tensile strength is 1,150 MPa (167 ksi) vs 880 MPa (128 ksi).

Which condition does FabDigit quote by default, N or VIM-VAR?

ANN is the default 13MoCrNi42-16-14 condition in the FabDigit quote flow (neither N nor VIM-VAR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, 13MoCrNi42-16-14-N or 13MoCrNi42-16-14 VIM-VAR?

13MoCrNi42-16-14 VIM-VAR, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for 13MoCrNi42-16-14-N; for welding the order is 13MoCrNi42-16-14 VIM-VAR first (poor, 15/100) then 13MoCrNi42-16-14-N (not recommended, 10/100).
