Blue spring steel, also known as blue-tempered steel, is a high-carbon steel that undergoes a heat treatment process to enhance its elasticity, toughness, and resistance to wear. The steel is usually alloyed with small amounts of manganese or silicon to improve its hardenability and strength. The "blue" in blue spring steel refers to the characteristic bluish oxide layer that forms on the surface during tempering, which helps protect the steel from corrosion. The manufacturing process typically involves cold rolling the steel into thin strips or sheets, followed by heating to specific temperatures to achieve the desired hardness and tempering to give it the appropriate spring characteristics. This process makes blue spring steel ideal for producing components like springs, fasteners, washers, clips, and other products that require high tensile strength and the ability to return to their original shape after deformation.

The advantages of blue spring steel include excellent spring properties, such as high tensile strength, fatigue resistance, and good ductility, which allow it to endure repeated stresses without permanent deformation. It is also highly resistant to wear, making it suitable for applications with frequent movement or friction. However, the material's high carbon content makes it prone to rust and corrosion, requiring protective coatings or proper maintenance in certain environments. Blue spring steel is also difficult to weld due to its high carbon content, and it can become brittle at very low temperatures. Despite these drawbacks, blue spring steel remains a preferred material for applications requiring durability, resilience, and a long service life under mechanical stress.
