Stainless Steel N08535-ANN vs N08535 CW-1/4H
Stainless Steel · N08535 temper comparison
N08535-ANN and N08535 CW-1/4H are two conditions of the same stainless steel grade, N08535: ANN (annealed) versus CW-1/4H (1/4 Hard). The chemistry is identical, so every difference below comes from the condition. N08535 CW-1/4H is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 265 MPa (38.4 ksi) for N08535-ANN, about 119% more; tensile strength follows at 790 MPa (115 ksi) vs 590 MPa (85.6 ksi). In exchange, N08535-ANN is the more ductile: elongation 45% versus 18% for N08535 CW-1/4H, and N08535 CW-1/4H is harder (250 HB vs 160 HB). N08535-ANN runs hotter in service (550°C vs 300°C continuous).
N08535-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
N08535 CW-1/4HChoose it when strength drives the design.
N08535-ANN vs N08535 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.
