Super Duplex mit hohem Standard Musteranpassung

Difference Between Duplex and Super Duplex

Since the super duplex material has more chromium, nickel and molybdenum content, it is expensive than the standard duplex grades. There are different grades of standard duplex and super duplex materials. Each different type has different material composition. Based on the material composition, the prices vary.

Super Duplex

Whilst duplex alloys were developed around a 22% Cr addition level, super duplex alloys utilise a higher 25%Cr base composition to increase the level of corrosion resistance achievable. In general, they are twice as strong as either austenitic or ferritic stainless steels. They achieve good toughness and ductility, somewhere between the two.
