Stainless Steel 410Cb Annealed vs 410Cb Q&T
Stainless Steel · 410Cb temper comparison
410Cb Annealed and 410Cb Q&T are two conditions of the same stainless steel grade, 410Cb: Annealed versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 410Cb Q&T is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 290 MPa (42.1 ksi) for 410Cb Annealed, about 114% more; tensile strength follows at 790 MPa (115 ksi) vs 490 MPa (71.1 ksi). In exchange, 410Cb Annealed is the more ductile: elongation 25% versus 18% for 410Cb Q&T, and 410Cb Q&T is harder (240 HB vs 170 HB). 410Cb Annealed runs hotter in service (650°C vs 590°C continuous). On the shop floor, 410Cb Annealed welds better (good vs fair).

410Cb Annealed vs 410Cb Q&T: 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.

410Cb Annealed vs 410Cb Q&T — frequently asked
Is 410Cb Q&T stronger than 410Cb Annealed?
Yes. 410Cb Q&T has a typical yield strength of 620 MPa (89.9 ksi) against 290 MPa (42.1 ksi) for 410Cb Annealed — about 114% more. Tensile strength is 790 MPa (115 ksi) vs 490 MPa (71.1 ksi).
Which condition does FabDigit quote by default, Annealed or Q&T?
Annealed is the default 410Cb 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, 410Cb Annealed or 410Cb Q&T?
410Cb Annealed, by a small margin. Both rate fair for machinability — 50/100 against 42/100 for 410Cb Q&T; for welding the order is 410Cb Annealed first (good, 60/100) then 410Cb Q&T (fair, 50/100).
