GOST 8732-78 Seamless hot-deformed low carbon A106 A36 Q345 ST52 12Mn 16Mn 42CrMn welded carbon steel pipes round tubing
Structural steel plate:
It is mainly used for the production of steel structures, bridges, ships and vehicles.
Weathering steel plate:
The addition of special elements (P, Cu, C, etc.) has good corrosion resistance and atmospheric corrosion resistance, and is used in the production of containers, special vehicles, and also for building structures.
Hot rolled special steel plate:
Carbon steel, alloy steel and tool steel for general mechanical structure are used in the production of various mechanical parts after heat treatment engineering.
Steel plate for steel tube:
It has good processing performance and compressive strength, and can be used to produce high pressure gas pressure vessels with contents less than 500L filled with LPG, acetylene and various gases.
Carbon Steel Welded Pipes / Tubes
The properties of carbon steel are high hardness, strength, wear resistance and anti-corrosion.
Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel's hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength, and it is less expensive than other steels.
