Duplex Steel Seamless Tubes are formed with the combination of iron, chromium and nickel alloy considering two-phase microstructure of austenitic and ferritic. These seamless tubes exhibit superior tensile strength and resistance to corrosion. Thus these have greater weldability and toughness. Furthermore, these possess outstanding resistance to stress corrosion cracking and intergranular corrosion at high-temperature circumstances. The existence of chromium content prevents from corrosion and effects embrittlement at a temperature above 300 degrees C. At low-temperature circumstances these offers good ductility and formability.
The annealing or solution treatment is performed and rapidly cooled down after heating. The tubes possess excellent weldability. Thus this weldability is obtained through the standard welding process.
