Stainless Steel 405 Annealed vs 405 Cold Drawn
Stainless Steel · 405 temper comparison
405 Annealed and 405 Cold Drawn are two conditions of the same stainless steel grade, 405: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 405 Cold Drawn is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 280 MPa (40.6 ksi) for 405 Annealed, about 61% more; tensile strength follows at 585 MPa (84.8 ksi) vs 480 MPa (69.6 ksi). In exchange, 405 Annealed is the more ductile: elongation 28% versus 18% for 405 Cold Drawn, and 405 Cold Drawn is harder (190 HB vs 155 HB).
405 AnnealedChoose it when the part is bent, formed or impact-loaded.
405 Cold DrawnChoose it when strength drives the design.
405 Annealed vs 405 Cold Drawn: 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.

405 Annealed vs 405 Cold Drawn — frequently asked
Is 405 Cold Drawn stronger than 405 Annealed?
Yes. 405 Cold Drawn has a typical yield strength of 450 MPa (65.3 ksi) against 280 MPa (40.6 ksi) for 405 Annealed — about 61% more. Tensile strength is 585 MPa (84.8 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Annealed is the default 405 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, 405 Annealed or 405 Cold Drawn?
405 Cold Drawn, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 405 Annealed; for welding the order is 405 Annealed first (very good, 70/100) then 405 Cold Drawn (good, 65/100).
