Products Details
1 SUP10 spring steel is a tough, shock resisting, shallow hardening chromium vanadium steel having high fatigue and impact resistance in the heat treated condition. 
2 SUP10 is used extensively in gears, pinions, springs, shafts, axles, pins, bolts, etc., which require high modulus of resilience.
3 SUP10 steel is also widely used in the manufacturing of valve springs, piston rods, pump parts, and spline shaft.
