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.

Zinc plated soft iron gasket washer is made of soft iron, and then covered by yellow or white zinc plated on it to avoid rust, as pure soft iron is very easy to be rusted. Soft iron has low retentivity as loses its magnetism easily, whereas, hard iron retains its magnetic property for a long period.

Zinc plated carbon steel gasket washer is made of carbon steel, and then covered by yellow or white zinc plated on it to avoid rust, as pure soft iron is very easy to be rusted.
