1.4466 Datasheet
X1CrNiMoN25-22-2
stainless steel; corrosion resistant steel; austenite
Petrochemicals
The material 1.4466 is an austenitic chromium-nickel-molybdenum steel with excellent chemical resistance. Due to its special corrosion resistance in acidic media, this grade is used for the construction of highly stressed equipment that comes into contact with aggressive solutions such as nitric acid or urea.
