super duplex 2507 uns s32750 pipes

Compared with ferritic stainless steel and austenitic stainless steel, duplex stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.

Due to its increased yield strength, thinner duplex stainless steel sections can be fabricated, resulting in significant weight savings. This makes duplex stainless steel a popular choice for structural applications and pressure vessels. Duplex steels have very high PREN or pitting resistance equivalent numbers. These values range from 22 to 45. Compared to austenitic stainless steels, dual-phase steels have improved strength and improved resistance to localized corrosion, especially pitting, crevice corrosion, and stress corrosion cracking.
