A106 Gr. B carbon steel pipe
gnee is a major supplier of seamless steel pipes, we provide high quality pipes to customers all over the world according to their needs.
A106 GR. B steel pipe is a seamless carbon steel pipe used in high temperature environments. Its carbon content is 0.3%, its manganese content is 0.29-1.06%, its minimum yield strength is 240 MPa, and its minimum tensile strength is 415 MPa. A106 GR. Class B seamless pipe is best suited for applications that transport hot gases and fluids at high temperatures and withstand large amounts of pressure while being economical and long-term wear-resistant.
Additionally the A106 GR. B The cold drawing finishing process of high-temperature pipes must be solid solution annealed in accordance with the heat treatment chapter to restore ferrite. A106 Grade B low carbon steel pipe, commonly used in industries such as oil and gas refineries and petrochemical plants.
