BSS Spring Steel supplies medium carbon steel in grades: EN9, EN45.

Medium carbon steel contains carbon from 0.30% to 0.60%. It’s stronger and more durable than low-carbon steel but still offers at least some ductility. Main properties of medium carbon steel are low hardenability, medium strength, ductility, and toughness.

This steel can be heat treated and quenched to further adjust the microstructure and mechanical properties.

Many automotive parts are made of medium-carbon steel. Popular applications include making shafts, axles, gears, crankshafts, couplings, forgings, rails, railway wheels, and rail axles.
