Grey cast iron is a type of cast iron. Carbon is present in cast iron in the form of flake graphite. The fracture is grey. It has good casting and cutting properties and good abrasion resistance. Used in the manufacture of racks, boxes, etc. Grey cast iron graphite is flaky, the effective bearing area is relatively small, the graphite tip is easy to produce stress concentration, so grey cast iron strength, plasticity, toughness are lower than other cast iron. But has excellent vibration damping, low gap sensitivity and high wear resistance.
Due to the high carbon content of grey cast iron, rough structure, tensile strength is not high, but brittle, but excellent compressive properties. Grey iron grade with HT plus tensile strength grade. Grey iron casting has 6 levels: HT100.HT150.HT200.HT250.HT300.HT350. they have a certain tensile strength, with good wear resistance, vibration resistance and easy machinability, can be in the aging or heat treatment to maintain a high degree of accuracy. Mostly used for mechanical parts, such as machine tool seat, cast iron platform plate, hydraulic piston, plastic crushing mechanism, pulley and so on.
In addition, grey cast iron has good impact strength, corrosion resistance, good resistance to heat, etc., which makes it able to stop impacts, thus helping to resist disasters and destructive processes, is widely used in the manufacture of a variety of production equipment, can be used for a long time in a variety of environments, and can better resist high temperature environments.
As grey iron casting manufacturer, we produce a wide range of other castings, like agriculture casting, water pump casting, hydraulic casting and so on are very useful parts, which are widely used in various industries, mostly used for mechanical parts such as Machine Tool Mounts, Cast Iron Platform Plates, Hydraulic Pistons, Plastic Crushing Mechanisms, Belt Pulleys and so on.
