30CrMoA Round Bar Description

30CrMoA alloy round steel material complies with the national standard GB/T3077 and has excellent mechanical properties and corrosion resistance. The main components of 30CrMoA steel round bar include chromium, molybdenum and various other alloying elements, which give it high strength, high toughness, and good processing properties. In many engineering fields, 30crmoA alloy round steel is widely used in the manufacture of heavy structural components, shaft parts, and important components. 30CrMoA alloy structural steel is mainly used in structures such as ships, vehicles, aircrafts, missiles, weapons, railways, bridges, pressure vessels, machine tools, etc.

30CrMoA round bar has good wear resistance and can be used for a long time in friction and wear environments without being easily damaged. 30CrMoA has good welding performance and can be used to manufacture welding structural parts and high pressure conduits in the chemical industry. 30CrMoA alloy steel bar is used to manufacture fasteners that work below 450°C, as well as flanges and nuts that are subjected to high pressure below 500°C. 30CrMoA alloy steel round bar is particularly suitable for manufacturing conduits that work at 300 atmospheres and below 400°C.
