    Description

    Cast iron CHH16 used: for the manufacture of parts of heat-resistant in air up to 900 °C, wear resistant at normal and elevated temperatures, resistant to inorganic acids high concentration (rebar chemical engineering, furnace fittings, the details of cement kilns).

    Note

    Chromium wear-resistant and heat-resistant high-alloy cast iron.
