    Description

    Cast iron CHH16M2 used: for the manufacture of parts with high resistance to impact-abrasive wear and abrasion in the mills, shot-blasting and shot-blasting chambers (wear-resistant parts of hydraulic machines, which pump abrasive mixture, lining palarivattom, grinding details of coal — and ore-grinding mills, bucket bashmetov, sklesi, heat, is highly resistant blades blast wheel impeller).

    Note

    Chromium wear-resistant alloyed cast iron.
