Stainless Steel 1.4374-C1150 vs 1.4374-CD
Stainless Steel · 1.4374 temper comparison
1.4374-C1150 and 1.4374-CD are two conditions of the same stainless steel grade, 1.4374: C1150 (cold worked to min. 1150 MPa tensile) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4374-C1150 is the stronger of the two: yield strength 950 MPa (138 ksi) against 700 MPa (102 ksi) for 1.4374-CD, about 36% more; tensile strength follows at 1,200 MPa (174 ksi) vs 950 MPa (138 ksi). In exchange, 1.4374-CD is the more ductile: elongation 20% versus 10% for 1.4374-C1150, and 1.4374-C1150 is harder (350 HB vs 280 HB). 1.4374-CD runs hotter in service (400°C vs 325°C continuous). On the shop floor, 1.4374-CD welds better (65 vs 55 out of 100).

1.4374-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4374-C1150 vs 1.4374-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.

1.4374-C1150 vs 1.4374-CD — frequently asked
Is 1.4374-C1150 stronger than 1.4374-CD?
Yes. 1.4374-C1150 has a typical yield strength of 950 MPa (138 ksi) against 700 MPa (102 ksi) for 1.4374-CD — about 36% more. Tensile strength is 1,200 MPa (174 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, C1150 or CD?
Annealed is the default 1.4374 condition in the FabDigit quote flow (neither C1150 nor CD). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 1.4374-C1150 or 1.4374-CD?
1.4374-CD, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 1.4374-C1150; for welding the order is 1.4374-CD first (good, 65/100) then 1.4374-C1150 (good, 55/100).
