1. SM45 steel
Is a high quality carbon steel for plastic mould, compared with 45 carbon structural steel quality, sulfur, phosphorus content in the steel, steel cleanness. Because the harden ability of steel, plastic mold manufacturing large size, generally with the hot, hot forging die or normalized condition, low hardness, poor resistance to abrasion. Small plastic mold manufacturing, processing can obtain higher hardness and better toughness by tempering. Carbon content of the steel is high, water quenching cracks are easy to occur, generally by oil quenching. The steel has the advantages of low price, good machine ability, high hardness after quenching, quenching and tempering treatment has good strength and toughness and wear resistance, is widely used in plastic mold manufacturing, small, low grade
