Stainless Steel 436 Cold Drawn vs 436 Temper Rolled 1/4 Hard
Stainless Steel · 436 temper comparison
436 Cold Drawn and 436 Temper Rolled 1/4 Hard are two conditions of the same stainless steel grade, 436: Cold Drawn versus Temper Rolled 1/4 Hard (1/4 Hard). 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 480 MPa (69.6 ksi) for 436 Temper Rolled 1/4 Hard, about 15% more; tensile strength follows at 655 MPa (95 ksi) vs 620 MPa (89.9 ksi). 436 Temper Rolled 1/4 Hard runs hotter in service (815°C vs 425°C continuous). On the shop floor, 436 Temper Rolled 1/4 Hard forms better (good vs fair).
436 Cold DrawnChoose it when strength drives the design.
436 Temper Rolled 1/4 HardChoose it when the part sees heat.
436 Cold Drawn vs 436 Temper Rolled 1/4 Hard: 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.
