Duplex Steel is stainless steel that is consists of 25% chromium, 7% nickel, 4% molybdenum, and other alloying elements. Super Duplex Stainless Steel grades have a combination of microstructure of austenite and ferrite in an equal proportion. The tensile strength of Super Duplex Stainless Steel Pipe Fittings is around 800 Mpa, which is much stronger than ferritic and austenitic steel grades. Some of the types of these fittings are Super Duplex Steel 45 Degree Elbow, Pipe Fitting, Concentric Reducer, Equal Tee, Short Stub End, Long Stub End, Pipe Bend, U Bend, Equal Cross, and many more.

Features Of the buttweld fittings:
- These super duplex steel provides excellent corrosion resistance in chloride environments and from stress cracking corrosion.
- They also gives great resistance to general corrosion and resistance to crevice corrosion and pitting corrosion.
- These fittings have extreme mechanical power and other physical characteristics.
- These buttweld fittings are resistant to erosion-corrosion and fatigue corrosion and presents many advantages in different applications.
- Theyeven presents many other properties like good weldability, machinability, and fabricability.
Difference between duplex and super duplex buttweld fittings:
Duplex stainless steels are having a composition of 22% chromium, whereas super duplex stainless steels are having a composition of 25% chromium. With an increament of chromium content, the level of pitting corrosion resistance is also increased.
