    Description

    Alloy 06KHN28MT used: for the manufacture of welded structures and components operating in sulfuric acid of low concentration (20%) at temperatures up to 60 °C and under the action of hot phosphoric acid; welded structures and components operating in environments less aggressive than for steel grade 06HN28MDT.

    Note

    Alloy for corrosion-resistant iron-based.
    The alloy has a satisfactory resistance to intergranular corrosion.
