20G Boiler Tube

20G steel pipe is GB/5310 national standard steel number (foreign corresponding grade: Germany st45.8, Japan STB42, US SA106B), which is the most commonly used steel for boiler steel pipe. 20G Boiler Tube chemical composition and mechanical properties are basically the same as those of 20 plates. 20G steel has certain normal temperature and medium-high temperature strength, low carbon content, good plasticity and toughness, and good cold-hot forming and welding performance.

Compared with solid steel such as round steel, the 20G steel pipe is lighter in weight when it has the same bending and torsional strength. 20G is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycles, Shelf and steel scaffolding used in construction.
