Octagonal Ring Joint Gaskets

F5 moly octagonal ring type joint gasket ASME B16.20 is made of F5 chrome moly according to ASME B16.20 specification. It has a fairly high electrical conductivity among wrought alloy steels in the same category. In addition, it has a moderately high base cost and a moderately high embodied energy.

F55 ring type joint gasket has high resistance to stress corrosion cracking in halide containing environments, high resistance to pitting and crevice corrosion, high resistance to general corrosion, high mechanical strength and high resistance to erosion corrosion and corrosion fatigue.
