Description: URANUS® B25 (UR B25) is a 18% Ni, 20% Cr, 6% Mo superaustenitic stainless steel grade with 0.2 % nitrogen additions, particularly designed to be cost effective. The 18% nickel and 0.7% copper additions combined with the chromium and molybdenum additions improve the behavior of the steel in many corrosive solutions encountered for example in chemical and petrochemical processes or chloride containing solutions. The alloy is also seawater resistant and has extensively been used in offshore industries (It has not to be used in stagnant seawater application with temperatures higher than 30° 86°F). Thanks to the 18% Nickel and the 0.2 Nitrogen additions, the microstructure is austenitic. Information provided by manufacturer. |
