Stainless Steel 310Cb Annealed vs 310Cb-AW
Stainless Steel · 310Cb temper comparison
310Cb Annealed and 310Cb-AW are two conditions of the same stainless steel grade, 310Cb: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 310Cb-AW is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 310 MPa (45 ksi) for 310Cb Annealed, about 6% more. In exchange, 310Cb Annealed is the more ductile: elongation 45% versus 35% for 310Cb-AW, and 310Cb-AW is harder (180 HB vs 160 HB).
310Cb AnnealedChoose it when the part is bent, formed or impact-loaded.
310Cb-AWChoose it when strength drives the design.
310Cb Annealed vs 310Cb-AW: 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.

310Cb Annealed vs 310Cb-AW — frequently asked
Is 310Cb-AW stronger than 310Cb Annealed?
Yes. 310Cb-AW has a typical yield strength of 330 MPa (47.9 ksi) against 310 MPa (45 ksi) for 310Cb Annealed — about 6% more. Tensile strength is 600 MPa (87 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, Annealed or AW?
Annealed is the default 310Cb 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, 310Cb Annealed or 310Cb-AW?
310Cb Annealed, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 310Cb-AW; for welding the order is 310Cb Annealed first (very good, 75/100) then 310Cb-AW (very good, 70/100).
