steel? Here\u2019s the short version first: clean the part, heat it in a carbon- or nitrogen-rich environment at the right temperature and time, quench if the method needs it, then temper. That sequence gives you a very hard, wear\u2011resistant outer layer (the \u201ccase\u201d) while the core stays tough and shock\u2011resistant. That is why case hardened steel is used for gears, camshafts, pins, dies, and small tools that see heavy wear and tear.
