Superior Steel Overseas is well known for the high volume of Duplex and Super Duplex products that it stocks. It supplies these duplex super duplex materials to countless companies around the world who use its product’s in numerous applications in many different situations.We can supply many different products in both Super Duplex and Duplex such as duplex welded pipes, seamless pipes and much more. They are available to buy from any of the company’s offices across the world.

Duplex

Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim being to produce a 50/50 mix, although, in commercial alloys, the mix may be 40/60 respectively.Duplex steels have improved strength over austenitic stainless steels and also improved resistance to localised corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. They are characterised by high chromium (19–28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as “super duplex” due to its higher resistance to corrosion.We supply duplex 2205 Pipe,duplex 2205 tubing, super duplex 2507 pipe and super duplex 2507 tubing and many more with high quality material,

The mechanical properties of Duplex steels are approximately double those of singular austenitic steels, and resistance to stress corrosion cracking is far superior to type 316 stainless steel in chloride solutions. Duplex steel has a ductile or brittle transition at approximately -50 degrees.

Super Duplex

Super Duplex is known to have better stress corrosion, cracking resistance and mechanical properties than any other type of steel. Super Duplexis an austenitic-ferritic iron chromium – nickel alloy with molybdenum addition. It has good resistance to pitting and a very good tensile strength and high resistance to stress corrosion cracking at moderate temperatures, compared to that of conventional austenitic stainless steels.The high corrosion resistance of Super Duplex pipeline supplies makes them ideal for onshore and offshore environments in oil and gas applications. Please see our industry pages for more information regarding the implications of Super Duplex piping.
