What is Alloy steel 42Crmo AISI 4140?
It belongs to ultra-high-strength steel, with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low-temperature impact toughness. It is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness
