The flanges are suitable for sub-zero temperatures. The material has excellent strength and durability. The alloy can withstand exposure to chloride-bearing environments. The grade is hardened through heat treatment to enhance crevice, creep, pitting, and uniform corrosion. The flanges are not affected by chemical oxidation or reduction. The material is moldable into different shapes, sizes, thicknesses, and designs to fit the customer requirements. They are found in slip-on, reducing, SOFF, SORF, WNRF, RTJ, reducing, plate, flat, spectacle, long weld neck, and orifice types. The flanges are classified into 150#, 300#, 600#, 900#, 1500#, 2500#, PN6, PN10, PN16, PN25, PN40, PN64, PN100, and PN160 based on pressure.
