20# Seamless Steel Pipe
GNEE is the main supplier of 20# alloy pipes, and we provide high-quality steel pipes to customers around the world according to their needs.
The chemical composition of 20# seamless alloy pipe contains 0.1%-0.25% carbon. Adding the main alloying elements manganese and silicon will significantly improve its corrosion resistance. The characteristic strength of 20# seamless pipe is slightly higher than that of 15# steel, with little quenching and no temper brittleness.
20# seamless steel pipes are divided into different varieties due to their different uses, including seamless steel pipes for structures, seamless steel pipes for fluid transportation, seamless steel pipes for low and medium pressure boilers, high-pressure boiler pipes and petroleum cracking pipes, etc.
