Stainless Steel 436 Annealed vs 436 Cold Drawn
Stainless Steel · 436 temper comparison
436 Annealed and 436 Cold Drawn are two conditions of the same stainless steel grade, 436: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 436 Cold Drawn is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 365 MPa (52.9 ksi) for 436 Annealed, about 51% more; tensile strength follows at 655 MPa (95 ksi) vs 530 MPa (76.9 ksi). In exchange, 436 Annealed is the more ductile: elongation 30% versus 14% for 436 Cold Drawn, and 436 Cold Drawn is harder (210 HB vs 175 HB). 436 Annealed runs hotter in service (815°C vs 425°C continuous).
436 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
436 Cold DrawnChoose it when strength drives the design.
436 Annealed vs 436 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.

436 Annealed vs 436 Cold Drawn — frequently asked
Is 436 Cold Drawn stronger than 436 Annealed?
Yes. 436 Cold Drawn has a typical yield strength of 550 MPa (79.8 ksi) against 365 MPa (52.9 ksi) for 436 Annealed — about 51% more. Tensile strength is 655 MPa (95 ksi) vs 530 MPa (76.9 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Annealed is the default 436 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.
When should I choose 436 Annealed over 436 Cold Drawn?
Pick 436 Annealed when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 436 Cold Drawn when strength drives the design.
