Plain carbon steel for mechanical engineering and automotive components.
It is usually supplied untreated but can be supplied to order in the normalized or finally heat treated (quenched and tempered to "Q" or "R" properties), which is adequate for a wide range of applications.
It is a very popular grade of through-hardening medium carbon steel, which is readily machinable in any condition. It is suitable for the manufacture of parts such as general-purpose axles and shafts, gears, bolts and studs. It can be further surface-hardened typically to 50-55 HRC by induction processes, producing components with enhanced wear resistance.
In its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties.
