Description

Q460C seamless steel pipe is a steel pipe made of Q460C steel with an outer diameter of 325 mm and a wall thickness of 35 mm. This seamless steel pipe is made of high-quality raw materials and precision processed through multiple processes. It has excellent physical properties and corrosion resistance and is widely used in petroleum, chemical industry, electric power, construction and other fields.
Q460C low alloy steel pipe contains appropriate amounts of carbon, manganese, silicon, phosphorus, sulfur and other elements. It has high strength and toughness, and also has good welding performance and corrosion resistance. This kind of steel has undergone multiple heat treatment processes during the manufacturing process, giving it excellent comprehensive properties and is widely used in bridges, ships, vehicles, construction and other fields.
Q460C seamless structural steel pipe refers to a steel pipe made by seamless rotary cutting or hot extrusion process. Compared with welded steel pipes, it has higher compressive strength and corrosion resistance. Seamless steel pipes have high precision in outer diameter and wall thickness, and good internal surface smoothness, which can ensure the fluid flow and sealing of the pipeline system.
