What is the material of seamless pipe 20G?

20G seamless pipe consists of carbon (0. 17 ~ 0.24)%, silicon (0. 17 ~ 0.37)%, manganese (0.35 ~ 0.65)%, phosphorus (≤0.040)% and sulfur (≤ 0.040).

20G seamless pipe has a hollow cross-section, and is widely used as a pipeline for oil, natural gas, gas, water and some solid substances. Compared with solid steel such as round steel, steel pipe is lighter in weight under the same bending and torsion strength, and it is an economic section steel, which is widely used to manufacture structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle racks, steel scaffolding for construction, etc.
