42CrMo alloy Seamless Steel tube is a kind of medium-carbon alloy structural steel pipe with good comprehensive performance and good hardenability. It is often used to manufacture gear, connecting rod, high strength bolt and other important parts in machining process.

42CrMo alloy steel pipe is the material in Chinese standard GB/T 3077, specification of alloy structural steel.

42CrMo alloy steel pipe belongs to ultra-high-strength steel pipe, 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. The steel pipe is also suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.
