Stainless Steel 1.4736 Annealed vs 1.4736 CR-1/4H
Stainless Steel · 1.4736 temper comparison
1.4736 Annealed and 1.4736 CR-1/4H are two conditions of the same stainless steel grade, 1.4736: Annealed versus CR-1/4H (1/4 Hard). The chemistry is identical, so every difference below comes from the condition. 1.4736 CR-1/4H is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 320 MPa (46.4 ksi) for 1.4736 Annealed, about 50% more; tensile strength follows at 590 MPa (85.6 ksi) vs 510 MPa (74 ksi). In exchange, 1.4736 Annealed is the more ductile: elongation 28% versus 10% for 1.4736 CR-1/4H, and 1.4736 CR-1/4H is harder (205 HB vs 170 HB).

1.4736 Annealed vs 1.4736 CR-1/4H: 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.
