Grey cast iron and nodular cast iron which is more wear-resisting

　　The expression of wear-resisting is a bit vague. According to your questions, should be considering the friction and wear.

　　

　　Abrasion resistance and materials almost all performance relationship, and under the condition of different wear mechanism, to improve the wear resistance of material performance also have different requirements. Due to friction material and test conditions each are not identical, expressed by abrasion index or by using abrasion tester under prescribed conditions for reducing the material measured in experiment (g/cm2), or its inverse, said wear resistance is a measuring parameters of friction and wear test.

　　

　　Cast iron wear basic consider wearing performance. In friction and wear of the application, the main use of cast iron antifriction sex, graphite and graphite off after the tiny holes can storage, improve the wear resistance. Common, such as phosphorus, boron, vanadium, titanium, formation of hard spots, improve the wear resistance. In contrast, the high hardness than the low wear resistance.

　　

　　Ductile iron has high strength, plasticity and toughness, wear resistance is higher than grey iron.

　　

　　If the introduction of another word: anti-wear. So the wear resistance of grey iron and ductile iron is bad.

　　

　　General use of wear-resistant white cast iron. Late to nickel iron, high manganese steel and high chromium cast iron, welding, metal ceramic, is not opened.
