摘要

A new steel for boiler piping and tubing application with remarkably improved tensile properties at elevated temperature was developed while maintaining the properties of ferritic alloy steels, including high thermal conductivity, low thermal expansion, and good weldability. By enabling the use of thinner/lighter weight pipes, this new product offers important advantages to the customer, as it contributes significantly to cost reduction and improved freedom in equipment design. Today, when the world's attention is drawn to global environmental problems, higher efficiency in thermal power plants, which are large consumers of fossil energy, and effective use of natural energy, are important challenges. To ensure that JFE Steel's piping and tubing for boiler applications, beginning with this pipe, continue to contribute to environmental improvement from the material side, in the future, JFE will promote the development of products with a wide range of unique and original features.
