Spring steel refers to special alloy steel used to manufacture various elastic components such as springs. According to performance requirements and usage conditions, it can be divided into ordinary alloy spring steel and special alloy spring steel. Spring steel has excellent comprehensive performance, precise shape and size. The company mainly produces 65Mn, 50CrVA, 60Si2Mn, 55CrSi, etc.

According to the GB/T 13304 standard, spring steel is divided into non alloy spring steel (carbon spring steel) and alloy spring steel based on chemical composition.

The carbon content (mass fraction) of carbon spring steel is generally 0.62% to 0.90%. According to its manganese content, it can be divided into general manganese content (mass fraction) (0.50%~0.80%) such as 65, 70, 85, and high manganese content (mass fraction) (0.90~1.20%) such as 65Mn.

Alloy spring steel is a type of steel based on carbon steel. By adding one or more alloy elements appropriately, the mechanical properties, hardenability, and other properties of the steel can be improved, thereby meeting the requirements for manufacturing various springs.In addition, some grades such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel, and stainless steel can also be used as spring steel.
