Stainless Steel 1.4982-CD vs 1.4982-ST
Stainless Steel · 1.4982 temper comparison
1.4982-CD and 1.4982-ST are two conditions of the same stainless steel grade, 1.4982: CD (cold drawn) versus ST (solution annealed). The chemistry is identical, so every difference below comes from the condition. 1.4982-CD is the stronger of the two: yield strength 600 MPa (87 ksi) against 330 MPa (47.9 ksi) for 1.4982-ST, about 82% more; tensile strength follows at 800 MPa (116 ksi) vs 660 MPa (95.7 ksi). In exchange, 1.4982-ST is the more ductile: elongation 45% versus 22% for 1.4982-CD, and 1.4982-CD is harder (250 HB vs 185 HB). 1.4982-ST runs hotter in service (700°C vs 600°C continuous).
1.4982-CDChoose it when strength drives the design.
1.4982-STChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4982-CD vs 1.4982-ST: 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.
