Stainless Steel 1.4662 2H vs 1.4662-CD
Stainless Steel · 1.4662 temper comparison
1.4662 2H and 1.4662-CD are two conditions of the same stainless steel grade, 1.4662: 2H (cold rolled, work-hardened strip) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4662 2H is the stronger of the two: yield strength 800 MPa (116 ksi) against 680 MPa (98.6 ksi) for 1.4662-CD, about 18% more; tensile strength follows at 950 MPa (138 ksi) vs 850 MPa (123 ksi). In exchange, 1.4662-CD is the more ductile: elongation 20% versus 12% for 1.4662 2H, and 1.4662 2H is harder (320 HB vs 285 HB). 1.4662-CD runs hotter in service (300°C vs 250°C continuous). On the shop floor, 1.4662-CD welds better (very good vs good).

1.4662 2H vs 1.4662-CD: 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.
