Duplex Series - Stainless Steel
Duplex Series of stainless steel includes Duplex & Super Duplex . Duplex stainless is a combination of both ferrite and austenite (50/50), having increased strength, improved weldability, higher toughness & resistance to corrosion. DML offer wide range of Duplex 2205 stainless steel material.
​
Super Duplex stainless like Duplex, is a mixed microstructure of austenite and ferrite. The main difference is that Super duplex has a higher Molybdenum and Chromium content which gives the material greater corrosion resistance. DML offers wide range of Super Duplex 2507 stainless steel material.
