Stainless Steel 410Cb-CD vs 410Cb Q&T
Stainless Steel · 410Cb temper comparison
410Cb-CD and 410Cb Q&T are two conditions of the same stainless steel grade, 410Cb: CD (cold drawn) 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 500 MPa (72.5 ksi) for 410Cb-CD, about 24% more; tensile strength follows at 790 MPa (115 ksi) vs 640 MPa (92.8 ksi). 410Cb Q&T is the more ductile: elongation 18% versus 15% for 410Cb-CD, and 410Cb Q&T is harder (240 HB vs 200 HB). 410Cb-CD runs hotter in service (650°C vs 590°C continuous). On the shop floor, 410Cb-CD machines more easily (good vs fair) and 410Cb-CD welds better (good vs fair).
410Cb-CDChoose it when the part sees heat, or when the part is machined in volume.
410Cb Q&TChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
410Cb-CD 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-CD vs 410Cb Q&T — frequently asked
Is 410Cb Q&T stronger than 410Cb-CD?
Yes. 410Cb Q&T has a typical yield strength of 620 MPa (89.9 ksi) against 500 MPa (72.5 ksi) for 410Cb-CD — about 24% more. Tensile strength is 790 MPa (115 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, CD or Q&T?
Annealed is the default 410Cb condition in the FabDigit quote flow (neither CD nor Q&T). 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-CD or 410Cb Q&T?
410Cb-CD. Its machinability rates good (55/100) against fair (42/100) for 410Cb Q&T; for welding the order is 410Cb-CD first (good, 60/100) then 410Cb Q&T (fair, 50/100).
