Description
Alloy KHN58V used: for the manufacture of welded structures operating in solutions of nitric acid in the presence ftorinol; pipe joints, fittings etc. with the body of the article with a thickness of up to 25.0 mm in equipment, working with radioactive media.
Note
Corrosion resistant alloy on a Nickel basis.
The alloy is resistant to intergranular corrosion in nitric-fluoride solutions.
