8 Years Exporter High Precision Seamless Steel Tubes Pipes High Quality Bk/Bks Cold Drawn Seamless Pipe
Short Description:
20CrMnTi alloy steel pipe is usually low carbon steel pipe with a carbon content of 0.17% -0.24%, also known as gear steel, and many parts are made of 20CrMnTi.
Here are three types of 20CrMnTi alloy steel tubes: cold drawn, hot rolled, and cold rolled bright seamless steel tubes, and the process is different for different needs. However, some units use round steel to produce parts without considering the use of steel pipes instead. Replacing 20CrMbTi round steel with 20CrMnTi steel pipe saves both raw materials and man-hours, which reduces costs and increases market competitiveness. 20CrMnTi and 30CrMnSiA seamless pipes are all carburized steel with good performance, high hardenability, after carburizing and quenching, they have a hard and wear-resistant surface and a tough core, with high low-temperature impact toughness, moderate weldability , Machinability is good after normalizing.
