Spring Steel - Copy Spring Steel Material Name
Spring Steel
Characteristics and Application Scope
Higher strength, plasticity and toughness, better hardenability, lower overheat sensitivity than manganese steel and lower than silicon High manganese steel has less decarburization tendency than silicon-manganese steel and has greater temper brittleness. Used in the vehicle and tractor industry to make leaf springs with heavy loads and large stresses and coil springs with larger diameters
