4140 Seamless Steel Round Tubing introduce
4140 Alloy Seamless Round Tubing
AISI 4140 grade steel is a low alloy steel that has chromium, molybdenum and manganese added to its alloy. Compared to 4130 grade steel, 4140 grade steel has a slightly higher carbon content. This versatile alloy gives AISI 4140 pipes good properties. For example, they have good atmospheric corrosion resistance and reasonable strength.
The chemical properties of 4140 grade seamless pipes reflect good comprehensive properties such as toughness, strength, fatigue strength and wear resistance. In order to improve the mechanical properties of the parts, they need to be heat treated. In addition, the alloy has self-scaling properties, which is an important feature of 4140 alloy steel pipes. The anti-scaling property can effectively reduce the cost of processing. AISI 4140 steel pipe is considered a mechanical pipe and is produced by cold working or hot working processes, usually ingot casting or continuous casting as required. After the pipe is hot worked, it can be cold worked and finally oiled before forming. Applying oil to the surface of ASTM A519 4140 grade pipe can effectively prevent dust accumulation.
