MAIN FEATURES & PERFORMANCE REQUIREMENTS
Spring steel is specialized in producing the spring and elastic components due to its elasticity under the condition of quenching and tempering. The elasticity of steel depends on its capacity of elastic deformation.
This allows objects made of spring steel to return to their original shape despite significant bending or twisting occurs.
Spriing steel should possess excellent combination property, such as mechanical property (limit of elasticity, ultimate strength, yield ratio), relaxation resistant, fatigue property, hardenability, physical and chemical property (heat resistance,low temperature resistant, antioxidation, corrosion resistance). To meet the above performance requirement, Spring steel has fine metallurgical quality ( high purity, homogeneity), excellent surface quality ( specially on surface defect and decarburization), precise external form and dimensions.
