Stainless Steel 1.4374-C700 vs 1.4374-CD
Stainless Steel · 1.4374 temper comparison
1.4374-C700 and 1.4374-CD are two conditions of the same stainless steel grade, 1.4374: C700 (cold worked to min. 700 MPa tensile) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4374-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 450 MPa (65.3 ksi) for 1.4374-C700, about 56% more; tensile strength follows at 950 MPa (138 ksi) vs 780 MPa (113 ksi). In exchange, 1.4374-C700 is the more ductile: elongation 45% versus 20% for 1.4374-CD, and 1.4374-CD is harder (280 HB vs 220 HB). 1.4374-C700 runs hotter in service (450°C vs 400°C continuous).
1.4374-C700Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4374-CDChoose it when strength drives the design.
1.4374-C700 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-C700 vs 1.4374-CD — frequently asked
Is 1.4374-CD stronger than 1.4374-C700?
Yes. 1.4374-CD has a typical yield strength of 700 MPa (102 ksi) against 450 MPa (65.3 ksi) for 1.4374-C700 — about 56% more. Tensile strength is 950 MPa (138 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, C700 or CD?
Annealed is the default 1.4374 condition in the FabDigit quote flow (neither C700 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.
When should I choose 1.4374-C700 over 1.4374-CD?
Pick 1.4374-C700 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 1.4374-CD when strength drives the design.
