Description
Cast iron CHH2 used: for the manufacture of parts with high corrosion resistance to the gas, air and alkaline media in terms of friction and wear and heat-resistant in air up to 600 °C (the grate beams and horn for sinter machines, the details of the contact devices of chemical equipment, the grid of tube furnaces of oil refineries, parts for turbochargers, parts steklomassy).
Note
Heat-resistant low-alloy chromium cast iron.
