Steel 20KH8VL
Designation
Description
20KH8VL steel is used: for the manufacture of casting parts of valves of oil refining units, furnace doubles, pump casings and other components operating in the hot oil much sulfur environments under pressure at temperatures up to +575 °C.
Note
Corrosion resistant steel heat-resistant martensitic class. Heat-resistant to more aggressive sulfur environments compared to steel stamps 20KH5ML, heat resistance to +600 °C.
Standards
Chemical composition
Fe is the basis.
According to GOST 2176-77 the chemical composition is given for steel grade 20Х8ВЛ. Deviations from the norms of chemical composition are allowed: for carbon ± 0.020%; for silicon ± 0.10%; on manganese, copper, chromium and nickel ± 0.10% each; by titanium and tungsten ± 0.050% each; by vanadium, molybdenum and niobium ± 0.020% each.
