Wear-resistant Cast Iron
Wear-resistant cast iron, abbreviated as WR cast iron, is a kind of cast iron with good wear resistance and strength. According to its chemical composition and microstructure, the main alloy elements added are C, Mn, Cr, Mo and Ni. It has been widely used in mining, chemical industry, electric power, petroleum, cement, food, rubber and other fields.
The main properties of WR cast iron are as follows:
First, the strength of WR cast iron is higher than that of ordinary cast iron. The tensile strength and yield strength of WR cast iron are 20%-40% higher than that of ordinary cast iron.
Second, WR cast iron has good castability, small shrinkage, few casting defects and good machinability.
Third, WR cast iron has excellent wear resistance. Due to its chemical composition and microstructure, WR cast irons wear resistance is much better than ordinary cast iron.
Fourth, WR cast iron has good heat resistance. Its working temperature is usually between 200 and 500 degrees Celsius.
Fifth, WR cast iron has good corrosion resistance. Its corrosion resistance is usually much better than ordinary cast iron because its chemical composition and microstructure.
In general, compared to ordinary cast iron, WR cast iron has better overall performance, such as high strength, good castability, excellent wear-resistance, good corrosion resistance and good heat resistance.
According to the standard YB/0362-1992, WR cast iron is used as a high-quality material for wear-resistant parts, especially for friction-bearing parts or wear parts. It can be used in mining, metallurgy, electric power, petroleum, chemical, rubber and other industries. In addition, this type of cast iron can also be used to make machine spare parts, shafts, gears, camshafts, axis bodies and other components.
In conclusion, WR cast iron is a kind of cast iron with excellent performance. It has good wear resistance, strength, castability, machinability, heat resistance and corrosion resistance, which is suitable for making wear-resistant parts with high-strength and wear-resistant requirements.
