SA106B – Seamless Carbon Steel for High-Temperature Service
SA106B is a seamless carbon steel grade widely used in the fabrication of high-temperature and pressure equipment. It is primarily designed for use in boilers, superheaters, and piping systems operating at elevated temperatures in the power generation and petrochemical industries.
Key features of SA106B include good high-temperature strength, excellent thermal conductivity, and reliable weldability. Its carbon composition provides sufficient hardness while maintaining ductility, making it easy to form, bend, and machine. The steel also offers good resistance to scaling and oxidation under continuous high-temperature exposure.
SA106B is typically supplied in seamless tube form, available in various diameters and wall thicknesses, meeting the requirements of ASME and ASTM standards. The steel’s uniform chemical composition and mechanical properties ensure safe and stable operation in demanding applications.
Applications of SA106B steel include high-temperature piping for boilers, superheaters, heat exchangers, and industrial pipelines. Its combination of strength, high-temperature resistance, and ease of fabrication makes it a preferred choice for engineers and fabricators in the power and chemical industries.
