Stainless Steel CA6N-ANN vs CA6N-F

Stainless Steel · CA6N temper comparison

CA6N-ANN and CA6N-F are two conditions of the same stainless steel grade, CA6N: ANN (annealed) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. CA6N-F is the stronger of the two: yield strength 900 MPa (131 ksi) against 560 MPa (81.2 ksi) for CA6N-ANN, about 61% more; tensile strength follows at 1,100 MPa (160 ksi) vs 760 MPa (110 ksi). In exchange, CA6N-ANN is the more ductile: elongation 24% versus 9% for CA6N-F, and CA6N-F is harder (350 HB vs 220 HB). CA6N-ANN runs hotter in service (400°C vs 250°C continuous). On the shop floor, CA6N-ANN machines more easily (fair vs poor) and CA6N-ANN welds better (very good vs fair).

CA6N-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

CA6N-FChoose it when strength drives the design.

CA6N-ANN vs CA6N-F — frequently asked

Is CA6N-F stronger than CA6N-ANN?

Yes. CA6N-F has a typical yield strength of 900 MPa (131 ksi) against 560 MPa (81.2 ksi) for CA6N-ANN — about 61% more. Tensile strength is 1,100 MPa (160 ksi) vs 760 MPa (110 ksi).

Which condition does FabDigit quote by default, ANN or F?

N+T is the default CA6N condition in the FabDigit quote flow (neither ANN nor F). 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-F?

CA6N-ANN. Its machinability rates fair (48/100) against poor (22/100) for CA6N-F; for welding the order is CA6N-ANN first (very good, 70/100) then CA6N-F (fair, 40/100).
