High Precision ASTM AISI 4130 4135 4140 4145h Seamless Round Steel Pipe Tube

Product Description

Product Description
Carbon steel pipes are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country's steel pipe industry.
General carbon steel pipe: It is made of 10, 20, 30, 35, 45 and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold-rolled. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transportation pipelines. 45, 40Cr and other medium carbon steel seamless pipes are used to manufacture mechanical parts, such as the stressed parts of automobiles and tractors. Generally, carbon steel pipes are used to ensure the strength and flattening test. Hot-rolled steel pipes are delivered in a hot-rolled state or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state.

Applications The application of carbon steel pipe is more and more extensive, and the domestic carbon steel pipe is growing at a rate of 10% every year, and it also has a great development prospect in petroleum, urea and other industries. The outstanding performance of carbon steel pipe is high yield strength and stress corrosion resistance, good weldability, and less susceptibility to cold cracking and hot cracking. By 2010, the unreasonable layout of the carbon steel pipe industry has been improved; the biggest advantage of carbon steel pipe rods is that they can be recycled 100%, which is in line with the national strategy of environmental protection, energy saving and resource saving
