Stainless Steel 1.4462-CD vs 1.4462 S31803
Stainless Steel · 1.4462 temper comparison
1.4462-CD and 1.4462 S31803 are two conditions of the same stainless steel grade, 1.4462: CD (cold drawn) versus S31803 (S31803 chemistry). The chemistry is identical, so every difference below comes from the condition. 1.4462-CD is the stronger of the two: yield strength 660 MPa (95.7 ksi) against 500 MPa (72.5 ksi) for 1.4462 S31803, about 32% more; tensile strength follows at 860 MPa (125 ksi) vs 740 MPa (107 ksi). In exchange, 1.4462 S31803 is the more ductile: elongation 30% versus 22% for 1.4462-CD, and 1.4462-CD is harder (280 HB vs 240 HB).
1.4462-CDChoose it when strength drives the design.
1.4462 S31803Choose it when the part is bent, formed or impact-loaded.
1.4462-CD vs 1.4462 S31803: 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.
