SA106B is the steel used for boiler steel pipes. It is an American standard and implements the standard ASME SA106M.
SA106B is often used to manufacture various boiler pipe fittings with high pressure, high temperature and high strength requirements, such as steam pipes, superheaters, headers, etc.
What is 106 Class B material?
ASTM A106 Gr B seamless pipe, ASTM A106 Gr B pipe, ASTM A106 GR. Grade B carbon steel seamless pipe is a common specification for seamless carbon steel pipes used in high temperatures. ASTM A106 Grade B is a low carbon steel pipe material commonly used in industrial plants, power plants, power plants, refineries and chemical plants.
