Material Notes:
Description: URANUS® B26 (UR B26) is a 25% Ni, 20% Cr, 6% Mo superaustenitic stainless steel grade with 0.2 % nitrogen additions, particularly designed for high structural stability and high corrosion resistance properties. The 25% nickel and 1% 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. The alloy behaves particularly well in sulphuric acid solutions and is well adapted for pollution control equipments (scrubbers...) The alloy is also seawater resistant and has extensively been used in offshore industries. The fully austenitic microstructure produced by the 25% nickel addition explains its high toughness at temperatures as low as -200°C (-328°F).Information provided by manufacturer.
