URANUS® 4565 is a 17% Ni, 24% Cr, 4.5% Mo super austenitic stainless steel grade with 0.4 % nitrogen additions, particularly designed for mechanical and high corrosion resistance properties.

The 17% nickel and 0.4 % nitrogen additions make the steel austenitic. The 24% chromium combined with 4.5% molybdenum and 0.4% nitrogen additions improve the behaviour of the steel in many corrosive solutions encountered for example in chemical and petrochemical processes. The alloy behaves particularly well in chloride containing solutions and is well considered for pollution control equipments (scrubbers...)

The alloy is also resistant to seawater and is used in offshore industries.

The austenitic microstructure obtained by nickel and high nitrogen additions explains its high toughness properties, obtained even down to -200°C (-28°F).
