Stainless Steel S44725 Annealed vs S44725 CR-Temper
Stainless Steel · S44725 temper comparison
S44725 Annealed and S44725 CR-Temper are two conditions of the same stainless steel grade, S44725: Annealed versus CR-Temper (cold Rolled / Temper Rolled). The chemistry is identical, so every difference below comes from the condition. S44725 CR-Temper is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 480 MPa (69.6 ksi) for S44725 Annealed, about 29% more; tensile strength follows at 720 MPa (104 ksi) vs 620 MPa (89.9 ksi). In exchange, S44725 Annealed is the more ductile: elongation 27% versus 14% for S44725 CR-Temper, and S44725 CR-Temper is harder (225 HB vs 180 HB). S44725 Annealed runs hotter in service (400°C vs 300°C continuous).
S44725 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S44725 CR-TemperChoose it when strength drives the design.
S44725 Annealed vs S44725 CR-Temper: 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.
