Stainless Steel S46800 Annealed vs S46800 Temper Rolled 1/4H
Stainless Steel · S46800 temper comparison
S46800 Annealed and S46800 Temper Rolled 1/4H are two conditions of the same stainless steel grade, S46800: Annealed versus Temper Rolled 1/4H (temper rolled / cold worked ~1/4 hard strip). The chemistry is identical, so every difference below comes from the condition. S46800 Temper Rolled 1/4H is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 310 MPa (45 ksi) for S46800 Annealed, about 45% more; tensile strength follows at 560 MPa (81.2 ksi) vs 480 MPa (69.6 ksi). In exchange, S46800 Annealed is the more ductile: elongation 32% versus 18% for S46800 Temper Rolled 1/4H, and S46800 Temper Rolled 1/4H is harder (200 HB vs 160 HB).

S46800 Annealed vs S46800 Temper Rolled 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.
