Spring kits - locking pin LS-1

Spring steel wire made from non-alloy carbon steel, engineered for applications that demand solid strength, good ductility, and dependable fatigue performance. EN 10270-1-SM is commonly used for tension, compression, and torsion springs where improved cold-coiling characteristics and easier forming are beneficial compared to the higher-strength SH grade. Its closest AISI equivalents typically fall within the 1050–1070 range, depending on the specific carbon content.

ISO 6931-1 4310-301 is a stainless austenitic spring steel known for its good mechanical properties and excellent corrosion resistance. It is commonly used in springs, clips, and other high-performance applications where both strength and corrosion resistance are required. The material contains chromium and nickel as main alloying elements, and may include a small amount of molybdenum for additional corrosion protection. It offers good formability and strength and is typically employed in environments with moisture or chemicals.
