EN8M steel (212M36) is a through solidifying carbon manganese free-cutting steel, for the most part provided untreated. En8m steel has great rigidity and is frequently utilized in riggings, shafts, focused on pins, studs, jolts, keys and so forth.
EN8M steel is a free-machining grade and is promptly machinable in any condition. It very well may be further surface-solidified to create segments with improved wear opposition, commonly to 50-55 HRC through acceptance forms.
Closely related grades include EN8DM (212A42)
