C60 | C60E QUALITY CARBON STEEL
C60/C60E carbon steel manufacturers and suppliers,supplied with round rods,square/flat bars,rollers,shafts,blocks and forging pieces.
C60/C60E carbon steel is a medium carbon steel according to EN standard. It has characteristics similar to that of C55 carbon steel which has high hardness and high strength after hardening.
C60/C60E steel is widely used for less exacting springs, shafts, bushings, crankshafts, etc.
