Stainless Steel SUS436L 1/4H vs SUS436L Annealed
Stainless Steel · SUS436L temper comparison
SUS436L 1/4H and SUS436L Annealed are two conditions of the same stainless steel grade, SUS436L: 1/4H (quarter hard) versus Annealed. The chemistry is identical, so every difference below comes from the condition. SUS436L 1/4H is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 300 MPa (43.5 ksi) for SUS436L Annealed, about 50% more; tensile strength follows at 550 MPa (79.8 ksi) vs 480 MPa (69.6 ksi). In exchange, SUS436L Annealed is the more ductile: elongation 30% versus 14% for SUS436L 1/4H, and SUS436L 1/4H is harder (190 HB vs 155 HB). SUS436L Annealed runs hotter in service (850°C vs 550°C continuous).
SUS436L 1/4HChoose it when strength drives the design.
SUS436L AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SUS436L 1/4H vs SUS436L 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.
