Stainless Steel 434 Annealed vs 434 Cold Drawn

Stainless Steel · 434 temper comparison

434 Annealed and 434 Cold Drawn are two conditions of the same stainless steel grade, 434: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 434 Cold Drawn is the stronger of the two: yield strength 510 MPa (74 ksi) against 365 MPa (52.9 ksi) for 434 Annealed, about 40% more; tensile strength follows at 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi). In exchange, 434 Annealed is the more ductile: elongation 25% versus 15% for 434 Cold Drawn, and 434 Cold Drawn is harder (200 HB vs 160 HB).

434 AnnealedChoose it when the part is bent, formed or impact-loaded.

434 Cold DrawnChoose it when strength drives the design.

434 Annealed vs 434 Cold Drawn — frequently asked

Is 434 Cold Drawn stronger than 434 Annealed?

Yes. 434 Cold Drawn has a typical yield strength of 510 MPa (74 ksi) against 365 MPa (52.9 ksi) for 434 Annealed — about 40% more. Tensile strength is 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi).

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

Annealed is the default 434 condition in the FabDigit quote flow. 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, 434 Annealed or 434 Cold Drawn?

434 Cold Drawn, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 434 Annealed; for welding the order is 434 Annealed first (good, 55/100) then 434 Cold Drawn (fair, 50/100).
