Stainless Steel 1.4374-C1000 vs 1.4374-CD

Stainless Steel · 1.4374 temper comparison

1.4374-C1000 and 1.4374-CD are two conditions of the same stainless steel grade, 1.4374: C1000 (cold worked to min. 1000 MPa tensile) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4374-C1000 is the stronger of the two: yield strength 800 MPa (116 ksi) against 700 MPa (102 ksi) for 1.4374-CD, about 14% more; tensile strength follows at 1,050 MPa (152 ksi) vs 950 MPa (138 ksi). In exchange, 1.4374-CD is the more ductile: elongation 20% versus 15% for 1.4374-C1000, and 1.4374-C1000 is harder (310 HB vs 280 HB). 1.4374-CD runs hotter in service (400°C vs 350°C continuous).

1.4374-C1000Choose it when strength drives the design.

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