Grade Introduction:
EN8M carbon steel (212M36) is a through hardening carbon manganese free-cutting steel, usually supplied untreated. This steel has good tensile strength. So it is often used in gears, shafts, stressed pins, studs, bolts, keys, etc.
 
EN8M carbon steel is a free-machining grade and is readily machinable in any condition. It can be further surface-hardened to produce components with enhanced wear resistance, typically to 50-55 HRC through induction processes. It is a free-cutting version of EN8M carbon steel made for easy machining.
