Steel 16NiCr4 +C vs 16NiCr4 +S

Steel · 16NiCr4 temper comparison

16NiCr4 +C and 16NiCr4 +S are two conditions of the same steel grade, 16NiCr4: +C (cold drawn) versus +S (treated for shearability). The chemistry is identical, so every difference below comes from the condition. 16NiCr4 +C is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 350 MPa (50.8 ksi) for 16NiCr4 +S, about 66% more; tensile strength follows at 700 MPa (102 ksi) vs 580 MPa (84.1 ksi). In exchange, 16NiCr4 +S is the more ductile: elongation 21% versus 11% for 16NiCr4 +C, and 16NiCr4 +C is harder (215 HB vs 165 HB).

16NiCr4 +CChoose it when strength drives the design.

16NiCr4 +SChoose it when the part is bent, formed or impact-loaded.

16NiCr4 +C vs 16NiCr4 +S — frequently asked

Is 16NiCr4 +C stronger than 16NiCr4 +S?

Yes. 16NiCr4 +C has a typical yield strength of 580 MPa (84.1 ksi) against 350 MPa (50.8 ksi) for 16NiCr4 +S — about 66% more. Tensile strength is 700 MPa (102 ksi) vs 580 MPa (84.1 ksi).

Which condition does FabDigit quote by default, +C or +S?

+A is the default 16NiCr4 condition in the FabDigit quote flow (neither +C nor +S). 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 welds better, 16NiCr4 +C or 16NiCr4 +S?

16NiCr4 +S. Its weldability rates good (55/100) against fair (50/100) for 16NiCr4 +C.
