Ductile Iron Wear Resistant Casings

The comprehensive performance of ductile iron is similar to that of steel which is typically used to produce parts that undertake complex stress or require high demands regarding strength, toughness, and wear resistance. Due to the spherical graphite in ductile iron suppressing the tendency toward fracture, ductile cast iron offers better ductility and toughness. Therefore, it provides high strength, plasticity, and wear resistance. Ductile iron castings are widely applied in automobile parts, concrete mixers, asphalt mixers, and other machines. Common parts made from ductile iron include valves, mixing arms, scraper blades, crankshafts, connecting-rods, gears, clutch plates, and hydraulic cylinders.

Zhuangzhi can manufacture various ductile iron castings according to your blueprints and technical requirement. Their reliable wearproof, yield strength and tensile strength can prolong the working lifetime of your machines.

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.
