The flanges are ideal for cryogenic temperatures. It can withstand continuous exposure to temperatures around -400 C. The alloy is hardened through heat treatment. It has excellent weldability and formability. The material is modifiable to different sizes, shapes, thickness, and designs to fit customer requirements. The alloy has good ductility and retains considerable strength even in low temperatures. However, the flanges are prone to embrittlement in high temperatures because they are designed to suit cryogenic environments. They are found in the following types lap joint, blind, slip-on, orifice, weld neck, orifice, reducing, SWORF, RTJ, WNRF, spectacle, flat, plate, and threaded. They are classified into 150#, 300#, 600#, 900#, 1500#, 2500#, PN6, PN10, PN16, PN25, PN40, PN64, PN100, and PN160.
