SA106B is a steel for boiler steel pipe, SA106B is an American grade, and China calls it 20G steel pipe. zhidao
SA106GrB steel pipe is mainly used to manufacture high-pressure and higher-parameter boiler pipe fittings, low-temperature section superheaters, reheaters, economizers, and water-cooled walls; Economizer pipes, etc., large-diameter pipes are used for steam pipes and headers with wall temperature ≤450 ° C (economizer, water-cooled wall, low-temperature superheater and reheater header), medium temperature ≤450 ° C, pipeline accessories, etc.
