Abstract

HCM2S is a high strength ferritic boiler tube alloy with strength at temperature more than 50% that of the commonly used 2.25 Cr alloy. The alloy, with very low carbon, needs no preheat nor post-weld heat treatment. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SA-480. Producer or source: Sumitomo Metal USA Corporation.
