Stainless Steel 310HCb-AW vs 310HCb-CD
Stainless Steel · 310HCb temper comparison
310HCb-AW and 310HCb-CD are two conditions of the same stainless steel grade, 310HCb: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 310HCb-CD is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 300 MPa (43.5 ksi) for 310HCb-AW, about 50% more; tensile strength follows at 690 MPa (100 ksi) vs 570 MPa (82.7 ksi). 310HCb-CD is harder — 210 HB against 185 HB for 310HCb-AW — which matters for wear surfaces and threads.
310HCb-CDChoose it when strength drives the design, or when surface hardness matters.
310HCb-AW vs 310HCb-CD: 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.

310HCb-AW vs 310HCb-CD — frequently asked
Is 310HCb-CD stronger than 310HCb-AW?
Yes. 310HCb-CD has a typical yield strength of 450 MPa (65.3 ksi) against 300 MPa (43.5 ksi) for 310HCb-AW — about 50% more. Tensile strength is 690 MPa (100 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, AW or CD?
Annealed is the default 310HCb condition in the FabDigit quote flow (neither AW nor CD). 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, 310HCb-AW or 310HCb-CD?
310HCb-CD. Its machinability rates fair (35/100) against poor (28/100) for 310HCb-AW; for welding the order is 310HCb-AW first (very good, 70/100) then 310HCb-CD (good, 65/100).
