I. the metallic gasket materials

1. carbon steel: recommended maximum operating temperature not exceeding 538 ° c, especially when the medium when it has oxidation. Quality of thin carbon plates are not suitable for the manufacture of inorganic acid, neutral or acidic salt solutions in equipment, if carbon steel by stress, used hot water operating conditions of equipment failure rate is very high. Carbon steel washers are typically used to high concentrations of acids and alkali solution. Brinell hardness of about 120.

2.18-8 304 stainless steel (chromium 18-20%, NI 8-10%), the recommended maximum operating temperature not exceeding 760 c. -196~538℃ temperature range, prone to intergranular corrosion and stress corrosion. Brinell hardness of 160. 3. 304L stainless steel carbon content of not more than 0. 3%. Recommended maximum operating temperature not exceeding 760 c. Corrosion properties similar to 304 stainless steel. Low carbon content reducing carbon from the lattice of precipitation, above resistance to intergranular corrosion of 304 stainless steel. Brinell hardness of about 140.
