Stainless Steel S44635 AS-WELDED vs S44635 Cold Worked
Stainless Steel · S44635 temper comparison
S44635 AS-WELDED and S44635 Cold Worked are two conditions of the same stainless steel grade, S44635: AS-WELDED (as-welded deposit) versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. S44635 Cold Worked is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 490 MPa (71.1 ksi) for S44635 AS-WELDED, about 33% more; tensile strength follows at 790 MPa (115 ksi) vs 660 MPa (95.7 ksi). In exchange, S44635 AS-WELDED is the more ductile: elongation 20% versus 15% for S44635 Cold Worked, and S44635 Cold Worked is harder (250 HB vs 220 HB). S44635 Cold Worked runs hotter in service (300°C vs 250°C continuous).
S44635 AS-WELDEDChoose it when the part is bent, formed or impact-loaded.
S44635 Cold WorkedChoose it when strength drives the design, or when the part sees heat.
S44635 AS-WELDED vs S44635 Cold Worked: 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.

S44635 AS-WELDED vs S44635 Cold Worked — frequently asked
Is S44635 Cold Worked stronger than S44635 AS-WELDED?
Yes. S44635 Cold Worked has a typical yield strength of 650 MPa (94.3 ksi) against 490 MPa (71.1 ksi) for S44635 AS-WELDED — about 33% more. Tensile strength is 790 MPa (115 ksi) vs 660 MPa (95.7 ksi).
Which condition does FabDigit quote by default, AS-WELDED or Cold Worked?
Annealed is the default S44635 condition in the FabDigit quote flow (neither AS-WELDED nor Cold Worked). 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, S44635 AS-WELDED or S44635 Cold Worked?
S44635 Cold Worked, by a small margin. Both rate fair for machinability — 46/100 against 40/100 for S44635 AS-WELDED; for welding the order is S44635 Cold Worked first (fair, 50/100) then S44635 AS-WELDED (fair, 45/100).
