Stainless Steel 310HCb Annealed vs 310HCb-AW
Stainless Steel · 310HCb temper comparison
310HCb Annealed and 310HCb-AW are two conditions of the same stainless steel grade, 310HCb: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 310HCb-AW is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 260 MPa (37.7 ksi) for 310HCb Annealed, about 15% more. In exchange, 310HCb Annealed is the more ductile: elongation 45% versus 32% for 310HCb-AW, and 310HCb-AW is harder (185 HB vs 170 HB).
310HCb AnnealedChoose it when the part is bent, formed or impact-loaded.
310HCb-AWChoose it when strength drives the design.
310HCb Annealed vs 310HCb-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.
