ASTM A714 Grade Ill steel pipe/tube, high-strength low-alloy steels have enhanced resistance to general atmospheric corrosion by weathering as commonly encountered in rural, urban, marine, and industrial environments.

The ASTM A714 steel pipe standard specification includes standard requirements for seamless and welded high-strength low-alloy steel pipes. ASTM A714 steel pipe should be used for pressure piping services and other general purposes. In these cases, saving

40Cr steel pipe is one of the most widely used structural steels. Because of its good mechanical properties, 40Cr steel pipe is widely used in the production of important quenching and tempering mechanical parts, such as gear bushings, connecting rods, sc

42CrMo4 steel pipe is a chromium-molybdenum alloy structural steel with good comprehensive mechanical properties, high hardenability and heat treatment properties. 42CrMo4 steel pipe is mainly used to manufacture forgings with higher strength requirements
