Stainless Steel 1.4462-CD vs 1.4462 WELD-SA
Stainless Steel · 1.4462 temper comparison
1.4462-CD and 1.4462 WELD-SA are two conditions of the same stainless steel grade, 1.4462: CD (cold drawn) versus WELD-SA (welded tube/pipe, solution annealed after welding). The chemistry is identical, so every difference below comes from the condition. 1.4462-CD is the stronger of the two: yield strength 660 MPa (95.7 ksi) against 520 MPa (75.4 ksi) for 1.4462 WELD-SA, about 27% more; tensile strength follows at 860 MPa (125 ksi) vs 750 MPa (109 ksi). In exchange, 1.4462 WELD-SA is the more ductile: elongation 28% versus 22% for 1.4462-CD, and 1.4462-CD is harder (280 HB vs 250 HB).
1.4462-CDChoose it when strength drives the design.
1.4462 WELD-SAChoose it when the part is bent, formed or impact-loaded.
1.4462-CD vs 1.4462 WELD-SA: 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.

1.4462-CD vs 1.4462 WELD-SA — frequently asked
Is 1.4462-CD stronger than 1.4462 WELD-SA?
Yes. 1.4462-CD has a typical yield strength of 660 MPa (95.7 ksi) against 520 MPa (75.4 ksi) for 1.4462 WELD-SA — about 27% more. Tensile strength is 860 MPa (125 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, CD or WELD-SA?
SA is the default 1.4462 condition in the FabDigit quote flow (neither CD nor WELD-SA). 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.
When should I choose 1.4462-CD over 1.4462 WELD-SA?
Pick 1.4462-CD when strength drives the design. Pick 1.4462 WELD-SA when the part is bent, formed or impact-loaded.
