Stainless Steel 330 As Welded vs 330 Cold Drawn

Stainless Steel · 330 temper comparison

330 As Welded and 330 Cold Drawn are two conditions of the same stainless steel grade, 330: As Welded (as-welded deposit) versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 330 Cold Drawn is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 330 MPa (47.9 ksi) for 330 As Welded, about 45% more; tensile strength follows at 700 MPa (102 ksi) vs 560 MPa (81.2 ksi). In exchange, 330 As Welded is the more ductile: elongation 28% versus 25% for 330 Cold Drawn, and 330 Cold Drawn is harder (200 HB vs 175 HB).

330 As WeldedChoose it when the part is bent, formed or impact-loaded.

330 Cold DrawnChoose it when strength drives the design.

330 As Welded vs 330 Cold Drawn — frequently asked

Is 330 Cold Drawn stronger than 330 As Welded?

Yes. 330 Cold Drawn has a typical yield strength of 480 MPa (69.6 ksi) against 330 MPa (47.9 ksi) for 330 As Welded — about 45% more. Tensile strength is 700 MPa (102 ksi) vs 560 MPa (81.2 ksi).

Which condition does FabDigit quote by default, As Welded or Cold Drawn?

Solution Annealed is the default 330 condition in the FabDigit quote flow (neither As Welded nor Cold Drawn). 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, 330 As Welded or 330 Cold Drawn?

330 Cold Drawn, by a small margin. Both rate poor for machinability — 32/100 against 26/100 for 330 As Welded.
