Cast iron VCH60
Designation
Description
Cast iron VCH60 used: for the manufacture of castings for stationary steam turbines, turbine equipment, nuclear power plants, elements of steam boilers and pipelines, hydraulic turbines, hydraulic locks, and other equipment engineering: casting 2 groups, operating at temperatures up to 250 °C, exposed to high static and dynamic loads and friction (pistons, housings gears, bearing, housing, worm wheels, bushings, bearing caps, nozzles, compressors, diaphragms, frames, Foundation, frame, exhaust parts, nozzles, compressors, gears, gear); castings group 1, operating at temperatures up to 350 °C and castings exposed to high specific pressures, static, dynamic loads and friction (diaphragms, clips, part, compressors, steam turbines, valves, compressors, nozzles, diffusers, blade, bearing shells, piston rings).
Standards
Chemical composition
According to GOST 7293-85 the chemical composition is given for castings with wall thickness up to 50 mm inclusive. For castings with a wall thickness exceeding 50 to 100 mm, the recommended content is C = 3.00-3.30%, Si = 2.40-2.80%.
