Stainless Steel Zeron 100 As Welded vs Zeron 100 Cold Drawn

Stainless Steel · Zeron 100 temper comparison

Zeron 100 As Welded and Zeron 100 Cold Drawn are two conditions of the same stainless steel grade, Zeron 100: As Welded (as-welded deposit) versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. Zeron 100 Cold Drawn is the stronger of the two: yield strength 790 MPa (115 ksi) against 660 MPa (95.7 ksi) for Zeron 100 As Welded, about 20% more; tensile strength follows at 950 MPa (138 ksi) vs 870 MPa (126 ksi). In exchange, Zeron 100 As Welded is the more ductile: elongation 25% versus 20% for Zeron 100 Cold Drawn, and Zeron 100 Cold Drawn is harder (300 HB vs 260 HB).

Zeron 100 As Welded vs Zeron 100 Cold Drawn — frequently asked

Is Zeron 100 Cold Drawn stronger than Zeron 100 As Welded?

Yes. Zeron 100 Cold Drawn has a typical yield strength of 790 MPa (115 ksi) against 660 MPa (95.7 ksi) for Zeron 100 As Welded — about 20% more. Tensile strength is 950 MPa (138 ksi) vs 870 MPa (126 ksi).

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

Solution Annealed is the default Zeron 100 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, Zeron 100 As Welded or Zeron 100 Cold Drawn?

Zeron 100 Cold Drawn, by a small margin. Both rate poor for machinability — 27/100 against 22/100 for Zeron 100 As Welded; for welding the order is Zeron 100 As Welded first (good, 65/100) then Zeron 100 Cold Drawn (good, 60/100).
