Locking pin T-S LST-S 10.5X55

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.
