42CrMo Hot Rolled Alloy Seamless Steel Pipe

Short Description:

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.

42CrMo seamless steel pipes are widely used in the petroleum, aerospace, chemical, power, boilers, military industries and other industries.


we can cut the 42CrMo seamless steel pipe into the length you demand, and can make the surface to be bright by milling and grinding at the Lathe, and can grind the outer diameter and wall thickness to be the dimension you demand.If the sizes are not available from the standard common stock sizes, and the quantity are not enough for the new production, then we need process the stock larger seamless pipes into the sizes you need. And we also can make steel pipes deep processing.
