Stainless Steel CA6N-ANN vs CA6N N+T

Stainless Steel · CA6N temper comparison

CA6N-ANN and CA6N N+T are two conditions of the same stainless steel grade, CA6N: ANN (annealed) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. CA6N N+T is the stronger of the two: yield strength 930 MPa (135 ksi) against 560 MPa (81.2 ksi) for CA6N-ANN, about 66% more; tensile strength follows at 1,020 MPa (148 ksi) vs 760 MPa (110 ksi). In exchange, CA6N-ANN is the more ductile: elongation 24% versus 19% for CA6N N+T, and CA6N N+T is harder (300 HB vs 220 HB). On the shop floor, CA6N-ANN machines more easily (fair vs poor).

CA6N-ANNChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

CA6N N+TChoose it when strength drives the design.

CA6N-ANN vs CA6N N+T — frequently asked

Is CA6N N+T stronger than CA6N-ANN?

Yes. CA6N N+T has a typical yield strength of 930 MPa (135 ksi) against 560 MPa (81.2 ksi) for CA6N-ANN — about 66% more. Tensile strength is 1,020 MPa (148 ksi) vs 760 MPa (110 ksi).

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

N+T is the default CA6N condition in the FabDigit quote flow. 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, CA6N-ANN or CA6N N+T?

CA6N-ANN. Its machinability rates fair (48/100) against poor (32/100) for CA6N N+T; for welding the order is CA6N-ANN first (very good, 70/100) then CA6N N+T (good, 62/100).
