Steel 36NiCrMo16 +N vs 36NiCrMo16 +SH

Steel · 36NiCrMo16 temper comparison

36NiCrMo16 +N and 36NiCrMo16 +SH are two conditions of the same steel grade, 36NiCrMo16: +N (normalized) versus +SH (+SH / peeled-turned bar in +QT condition). The chemistry is identical, so every difference below comes from the condition. 36NiCrMo16 +SH is the stronger of the two: yield strength 1,120 MPa (162 ksi) against 1,050 MPa (152 ksi) for 36NiCrMo16 +N, about 7% more. 36NiCrMo16 +SH is the more ductile: elongation 11% versus 9% for 36NiCrMo16 +N, and 36NiCrMo16 +N is harder (440 HB vs 400 HB). 36NiCrMo16 +SH runs hotter in service (350°C vs 250°C continuous). On the shop floor, 36NiCrMo16 +SH machines more easily (32 vs 22 out of 100).

36NiCrMo16 +N vs 36NiCrMo16 +SH — frequently asked

Is 36NiCrMo16 +SH stronger than 36NiCrMo16 +N?

Yes. 36NiCrMo16 +SH has a typical yield strength of 1,120 MPa (162 ksi) against 1,050 MPa (152 ksi) for 36NiCrMo16 +N — about 7% more. Tensile strength is 1,330 MPa (193 ksi) vs 1,450 MPa (210 ksi).

Which condition does FabDigit quote by default, +N or +SH?

+QT-40 is the default 36NiCrMo16 condition in the FabDigit quote flow (neither +N nor +SH). 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, 36NiCrMo16 +N or 36NiCrMo16 +SH?

36NiCrMo16 +SH, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for 36NiCrMo16 +N; for welding the order is 36NiCrMo16 +SH first (poor, 20/100) then 36NiCrMo16 +N (not recommended, 12/100).
