Stainless Steel 1.4434-AW vs 1.4434-CD

Stainless Steel · 1.4434 temper comparison

1.4434-AW and 1.4434-CD are two conditions of the same stainless steel grade, 1.4434: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4434-CD is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 350 MPa (50.8 ksi) for 1.4434-AW, about 31% more; tensile strength follows at 700 MPa (102 ksi) vs 590 MPa (85.6 ksi). In exchange, 1.4434-AW is the more ductile: elongation 30% versus 25% for 1.4434-CD, and 1.4434-CD is harder (225 HB vs 200 HB). On the shop floor, 1.4434-CD machines more easily (fair vs poor).

1.4434-AWChoose it when the part is bent, formed or impact-loaded.

1.4434-CDChoose it when strength drives the design, or when the part is machined in volume.
