Application | Seamless steel pipes are made of high-quality carbon steels such as 10#, 20#, 30#, 35#, 45#, low-alloy structural steels such as 16Mn, 5MnV, or composite steels such as 40Cr, 30CrMnSi, 45Mn2, 40MnB, hot-rolled or cold-rolled Made. Seamless pipes made of low carbon steel such as 10# and 20# are mainly used for fluid transportation pipelines, and seamless pipes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Generally, seamless steel pipes must be used for strength and flattening tests. Hot-rolled steel pipes are delivered in hot-rolled state or heat-treated state; cold-rolled steel pipes are delivered in heat-treated state. |
