Steel SNC836-A vs SNC836-N

Steel · SNC836 temper comparison

SNC836-A and SNC836-N are two conditions of the same steel grade, SNC836: A (solution annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. SNC836-N is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 460 MPa (66.7 ksi) for SNC836-A, about 26% more; tensile strength follows at 880 MPa (128 ksi) vs 720 MPa (104 ksi). In exchange, SNC836-A is the more ductile: elongation 22% versus 18% for SNC836-N, and SNC836-N is harder (262 HB vs 210 HB). On the shop floor, SNC836-A machines more easily (good vs fair).

SNC836-AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

SNC836-NChoose it when strength drives the design.

SNC836-A vs SNC836-N — frequently asked

Is SNC836-N stronger than SNC836-A?

Yes. SNC836-N has a typical yield strength of 580 MPa (84.1 ksi) against 460 MPa (66.7 ksi) for SNC836-A — about 26% more. Tensile strength is 880 MPa (128 ksi) vs 720 MPa (104 ksi).

Which condition does FabDigit quote by default, A or N?

QT is the default SNC836 condition in the FabDigit quote flow (neither A 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 is easier to machine, SNC836-A or SNC836-N?

SNC836-A. Its machinability rates good (55/100) against fair (42/100) for SNC836-N.
