Stainless Steel 1.4423-AW vs 1.4423-CD

Stainless Steel · 1.4423 temper comparison

1.4423-AW and 1.4423-CD are two conditions of the same stainless steel grade, 1.4423: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4423-CD is the stronger of the two: yield strength 820 MPa (119 ksi) against 700 MPa (102 ksi) for 1.4423-AW, about 17% more; tensile strength follows at 980 MPa (142 ksi) vs 900 MPa (131 ksi). 1.4423-AW is harder — 330 HB against 310 HB for 1.4423-CD — which matters for wear surfaces and threads.
