General purpose medium carbon steel delivered in as rolled condition. It can be further heat treated to achieve specific mechanical properties. The 0.45% carbon content is not favorable for welding. However, it can be weld with appropriate pre and post weld heat treatment. Surface hardness of 57~62 HRC can be achieved with cast hardening to a depth of approximately 1mm. Used for most transmission and motor parts of medium strength. Case hardened parts such as camshafts, gears, rocking levers etc. Simple hand tools and various types of fasteners and fixtures, machinery parts and components with medium stress.
Hot rolled or forged +Rough machined (black surface after Q/T)+ Turned (optional)

A medium carbon steel is used when greater strength and hardness is desired than in the “as rolled” condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned ground and polished.
Component parts for vehicles, shafts, bushings, crankshafts, connecting rods and parts for the machine building industry and steel for axes, knives, hammers etc.
