Stainless Steel CA6N-ANN vs CA6N N+T-HT
Stainless Steel · CA6N temper comparison
CA6N-ANN and CA6N N+T-HT are two conditions of the same stainless steel grade, CA6N: ANN (annealed) versus N+T-HT (N+T). The chemistry is identical, so every difference below comes from the condition. CA6N N+T-HT is the stronger of the two: yield strength 720 MPa (104 ksi) against 560 MPa (81.2 ksi) for CA6N-ANN, about 29% more; tensile strength follows at 860 MPa (125 ksi) vs 760 MPa (110 ksi). CA6N N+T-HT is harder — 255 HB against 220 HB for CA6N-ANN — which matters for wear surfaces and threads. CA6N N+T-HT runs hotter in service (450°C vs 400°C continuous). On the shop floor, CA6N-ANN forms better (28 vs 15 out of 100).
CA6N N+T-HTChoose it when strength drives the design, or when surface hardness matters.
CA6N-ANN vs CA6N N+T-HT: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

CA6N-ANN vs CA6N N+T-HT — frequently asked
Is CA6N N+T-HT stronger than CA6N-ANN?
Yes. CA6N N+T-HT has a typical yield strength of 720 MPa (104 ksi) against 560 MPa (81.2 ksi) for CA6N-ANN — about 29% more. Tensile strength is 860 MPa (125 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, ANN or N+T-HT?
N+T is the default CA6N condition in the FabDigit quote flow (neither ANN nor N+T-HT). 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-HT?
CA6N-ANN, by a small margin. Both rate fair for machinability — 48/100 against 40/100 for CA6N N+T-HT; for welding the order is CA6N-ANN first (very good, 70/100) then CA6N N+T-HT (good, 62/100).
