Description
Cast iron CHH28D2 used: for the manufacture of parts with high resistance against abrasive wear and galling in the conditions of milling equipment, screens and slezov, sintering machines and sand - blasting chambers and at elevated temperatures (wear-resistant parts of hydraulic machines, which pump abrasive mixture; lining palarivattom, grinding details of coal - and ore-grinding mills, bucket bashmetov, sklesi, heat, highly resistant to blast the blades of the impellers, inserts for reinforcement bars of the secondary cooling zone of continuous casting plants steel mills lining).
Note
Chromium wear-resistant and corrosion-resistant high-alloy cast iron.
