42CrMo 42CrMo4 AISI 4142 Carbon Steel Tube Pipe Seamless/Welded
42CrMo steel belongs to ultra-high strength steel, with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and resistance to multiple impact after quenching and tempering, and good impact toughness at low temperature. 42CrMo steel is suitable for manufacturing large and medium-sized plastic moulds which require certain strength and toughness.
