Product Description

4140 alloy steel round tube

4140  round steel tube or pipes are medium carbon alloy grades  with high tensile strength and toughness after quenching and tempereing, that is also to say q&t 4140 steel tube. It is widely used for various applications that require high tensile strength and toughness. The higherer Cr and Mo content can improve the hardness, ductility and strength after heat treatment such as Quenching and tempering.
