Stainless Steel S44535-ANN vs S44535 CW-1/4H
Stainless Steel · S44535 temper comparison
S44535-ANN and S44535 CW-1/4H are two conditions of the same stainless steel grade, S44535: ANN (annealed) versus CW-1/4H (cold worked, 1/4 hard strip). The chemistry is identical, so every difference below comes from the condition. S44535 CW-1/4H is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 330 MPa (47.9 ksi) for S44535-ANN, about 45% more; tensile strength follows at 610 MPa (88.5 ksi) vs 500 MPa (72.5 ksi). In exchange, S44535-ANN is the more ductile: elongation 27% versus 12% for S44535 CW-1/4H, and S44535 CW-1/4H is harder (207 HB vs 180 HB). S44535-ANN runs hotter in service (950°C vs 850°C continuous).
S44535-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S44535 CW-1/4HChoose it when strength drives the design.
S44535-ANN vs S44535 CW-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.
