Grey Iron Wear Resistant Castings

Due to the excellent wear resistance and shock absorption properties of grey cast iron, it is suitable for static castings that require low strength but undertake high loads with lower costs. The carbon content of grey cast iron is normally higher, up to 2.5-4%. This property makes the products easier to machine. Grey iron castings are commonly applied in machines, lathes, and auto accessories as lathe stands, lathe beds, bearing support, gear boxes, automobile cylinders, valves, and pumps.

Grey iron castings can be produced according to your blueprints and technical requirements. To increase their hardness, durability, and stability, heat treating is also available upon request.

Why choose us

• Reasonable Chemical Composition
  With the exception of common elements, precious metal is added as an alternative. Equipped with accurate analyzer, we are able to quickly detect and adjust the chemical content as needed to meet custom requirements.
• Advanced Metallurgy Technique
  A medium-frequency induction furnace is used for all castings to prevent any impurities and toxic gases from influencing the purity of molten iron and preventing segregation.
• Strict Temperature Controlling
  The best temperature control criteria has been developed based on our extensive experience, and inspectors carry out a strict quality control of each step to ensure the final quality.
• Advanced Casting Technique
  An advanced EPC casting process ensures the cast products feature fine grains and a dense structure.
• Advanced Heat Treating
  Several heat treating furnaces are responsible for annealing, normalizing and tempering to eliminate internal stress, prevent deformation, and increase product strength.

Zhuangzhi has devoted to custom wear resistant castings for more than 10 years. Currently the yield has reached up to 20,000 tons per year. These products have been widely serving in cement mixer truck, asphalt mixer, asphalt paver, crusher and other industry equipment. Upon your requirements against abrasion, impact, corrosion or heat, specific material will be chose to manufacture your wear resistant castings. And followings are the links to other castings.
