    Nickel-based alloys

    Nickel alloys are normaly considered when Nickel percentage is over 25%. These grades offer a  the highest  degree of corrosion resistance which makes it possible to use them in a wider range of applications

    due to their resistance to various acids (sulphuric acid, hydrochloric acid, phosphoric acid).

    By Standards:

    • ASTM, ASME, DIN, EURONORM, ISO, BS, AFNOR, JIS, GOST

    • Other technical specifications upon request.

    Delivery Condition

    • Annealed and Pickled
