Steel E460K2 +A vs E460K2 +C

Steel · E460K2 temper comparison

E460K2 +A and E460K2 +C are two conditions of the same steel grade, E460K2: +A (annealed) versus +C (cold drawn). The chemistry is identical, so every difference below comes from the condition. E460K2 +C is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 370 MPa (53.7 ksi) for E460K2 +A, about 59% more; tensile strength follows at 700 MPa (102 ksi) vs 560 MPa (81.2 ksi). In exchange, E460K2 +A is the more ductile: elongation 25% versus 12% for E460K2 +C, and E460K2 +C is harder (220 HB vs 160 HB). E460K2 +A runs hotter in service (400°C vs 350°C continuous). On the shop floor, E460K2 +A welds better (80 vs 70 out of 100).

E460K2 +AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

E460K2 +CChoose it when strength drives the design.

E460K2 +A vs E460K2 +C — frequently asked

Is E460K2 +C stronger than E460K2 +A?

Yes. E460K2 +C has a typical yield strength of 590 MPa (85.6 ksi) against 370 MPa (53.7 ksi) for E460K2 +A — about 59% more. Tensile strength is 700 MPa (102 ksi) vs 560 MPa (81.2 ksi).

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

+N is the default E460K2 condition in the FabDigit quote flow (neither +A nor +C). 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, E460K2 +A or E460K2 +C?

E460K2 +A. Its weldability rates very good (80/100) against very good (70/100) for E460K2 +C.
