The high chromium, molybdenum, and nitrogen contents of alloy Uranus B25 (also referred to as UR B25) and its pitting resistance equivalent number (PREN) of >=42 explain why the grade is very resistant to localized corrosion even in acidified oxidizing environments. The alloy has also been used for seawater applications. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-907. Producer or source: Industeel USA, LLC.
