The flanges are lowly alloyed but they exhibit excellent strength. They are ideal for high pressure environment because they are not prone to erosion. The alloy is resistant to pitting, crevice, uniform, and stress cracking corrosion. The material can withstand exposure to most organic and inorganic acids. It has a superb weldability and formability and retains its ductility even after continuous exposure to moderate or cryogenic temperatures. The most common types are slip-on, RTJ, SWORF, spectacle, blind, plate, square, orifice, WRNF, long weld neck, threaded, and lap joint. They are classified into 150#, 300#, 600#, 900#, 1500#, 2500#, PN6, PN10, PN16, PN25, PN40, PN64, PN100, and PN160.
