Duplex Stainless Steel was developed long back in 1930 and gradually finds its wide application because of its high
strength, good weldability, good toughness and resistance to stress corrosion cracking. This alloy finds its application in pressure
vessels, bridges, process plants and also in typically down to minus 50 degree centigrade applications. However, because of its
high alloy content thermal conductivities of duplex stainless steel are low. Casting this alloy is difficult and can be industrially
used after proper heat treatment.
