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)

En 353 steel has carbon content of 0.17% and the most common form of steel as it’s provides material properties that are acceptable for many automobile applications such as heavy duty gear, shaft, pinion, cam shafts, gudgeon pins [1,8]. It is neither externally brittle nor ductile due to its lower carbon content and lower hardness. As the carbon content increases, the metal becomes harder and stronger.
