The flanges are stronger than grades 1 and 2. They are more alloyed than the first two types in this series. The alloy has good formability and weldability. The material has an excellent strength that enhances ductility even in moderate temperatures. The grade is molded to fit the customer’s size, shape, and thickness specifications. The flanges are light and resistant to corrosion in chloride ion bearing environments. The alloy can withstand chlorine and sea water too. They are grouped into slip-on, weld neck, spectacle, socket, reducing, SORF, threaded, raised face, and orifice flanges. The classes include 150#, 300#, 600#, 900#, 1500#, 2500#, PN6, PN10, PN16, PN25, PN40, PN64, and PN100.
