These pipes and tubes are intended for the application need exceptional strength and corrosion resistance. S32750 is comprised of molybdenum, chromium and nickel content. Higher composition of molybdenum and chromium and little addition of nitrogen results outstanding resistance to chloride pitting and crevice corrosion. However, the duplex structure offers good resistance to pitting and chloride stress corrosion cracking. Application of Super Duplex S32750 Pipes and Tubes should be limited to applications up to 316 deg C.
Its service can be expanded up to elevated temperature but it can reduce corrosion resistance and toughness of grade. Super duplex structure has exceptional mechanical properties.
The duplex structure of pipes and tubes are highly resistive to uniform corrosion in organic acid containing acids such as acetic and formic acids. Additionally, it has exceedingly resistance to inorganic acids that contain chlorides. The ferritic structure of pipes and tubes is resistive to stress cracking in warm chloride conditions.

DESCRIPTION
The machining property of grade reduces the propensity to work harden. Forming property is higher because of higher yield strength. Welding is possible with all standard welding operations. However, preheating and post weld annealing is not required in the weld affected zones. The filler material may be used for welding.
CONCLUSION
Hot-working of Super Duplex S32750 Pipes and Tubes are required for shaping. It may be performed after heating between 1750 deg F to 2000 deg F and followed by fast cooling. Desired properties are attained after annealing temperature up to 1920 deg F to 2060 deg F. These pipes and tubes are not hardenable by heat treatment only cold working is recommended.
