Stainless Steel 436-1/2 Hard vs 436 Annealed
Stainless Steel · 436 temper comparison
436-1/2 Hard and 436 Annealed are two conditions of the same stainless steel grade, 436: 1/2 Hard (half hard) versus Annealed. The chemistry is identical, so every difference below comes from the condition. 436-1/2 Hard is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 365 MPa (52.9 ksi) for 436 Annealed, about 60% more; tensile strength follows at 725 MPa (105 ksi) vs 530 MPa (76.9 ksi). In exchange, 436 Annealed is the more ductile: elongation 30% versus 8% for 436-1/2 Hard, and 436-1/2 Hard is harder (240 HB vs 175 HB). 436 Annealed runs hotter in service (815°C vs 315°C continuous).
436-1/2 HardChoose it when strength drives the design.
436 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
436-1/2 Hard vs 436 Annealed: 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.

436-1/2 Hard vs 436 Annealed — frequently asked
Is 436-1/2 Hard stronger than 436 Annealed?
Yes. 436-1/2 Hard has a typical yield strength of 585 MPa (84.8 ksi) against 365 MPa (52.9 ksi) for 436 Annealed — about 60% more. Tensile strength is 725 MPa (105 ksi) vs 530 MPa (76.9 ksi).
Which condition does FabDigit quote by default, 1/2 Hard or Annealed?
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.
Which is easier to machine, 436-1/2 Hard or 436 Annealed?
436 Annealed. Its machinability rates good (58/100) against fair (52/100) for 436-1/2 Hard; for welding the order is 436 Annealed first (good, 65/100) then 436-1/2 Hard (good, 58/100).
