There are many kinds of alloy steels, which are generally divided into low alloy steels (content<5%), medium alloy steels (content 5%~10%) and high alloy steels (content>10%) according to the content of alloy elements; It is divided into high-quality alloy steel and special alloy steel according to quality; According to characteristics and applications, it can also be divided into alloy structural steel, stainless steel, acid resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special performance steel (such as soft magnetic steel, permanent magnetic steel, non magnetic steel

In addition to good hardenability, the hot workability, comprehensive mechanical properties, and decarburization resistance are also good for various important springs with large sections, such as large leaf springs and spiral springs for automobiles and locomotives. spring steel has higher strength, plasticity and toughness, better hardenability, lower overheating sensitivity than manganese steel, less decarburization tendency than silicon manganese steel, and greater temper brittleness. spring steel is used in vehicle and tractor industries to make leaf springs with heavy load and large stress and coil springs with large diameter.
