Steel C35E +C vs C35E +N

Steel · C35E temper comparison

C35E +C and C35E +N are two conditions of the same steel grade, C35E: +C (cold drawn) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. C35E +C is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 330 MPa (47.9 ksi) for C35E +N, about 52% more; tensile strength follows at 640 MPa (92.8 ksi) vs 570 MPa (82.7 ksi). In exchange, C35E +N is the more ductile: elongation 21% versus 11% for C35E +C, and C35E +C is harder (195 HB vs 170 HB).

C35E +CChoose it when strength drives the design.

C35E +NChoose it when the part is bent, formed or impact-loaded.

C35E +C vs C35E +N — frequently asked

Is C35E +C stronger than C35E +N?

Yes. C35E +C has a typical yield strength of 500 MPa (72.5 ksi) against 330 MPa (47.9 ksi) for C35E +N — about 52% more. Tensile strength is 640 MPa (92.8 ksi) vs 570 MPa (82.7 ksi).

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

+QT is the default C35E condition in the FabDigit quote flow (neither +C nor +N). 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, C35E +C or C35E +N?

C35E +N. Its weldability rates good (58/100) against fair (50/100) for C35E +C.
