  1. The Difference between Cast Iron and Ductile Iron - on Aug. 31, 2012
    Some customers asked us about the difference between cast iron and ductile iron, including their advantages and disadvantages. Herein, we listed their main properties and hope to give you a reference for material selection.
  2. SG Iron Grades - on Aug. 29, 2012
    SG iron is also called as spheroidal graphite cast iron, in USA, they are also called as ductile iron. There are many different sg iron grades in different countries and standards, however, most of grades have similar requirements to the mechanical properties, especially to tensile strength, yield strength and elongation.
  3. Grey Iron Grades - on Aug. 28, 2012
    There are many different grey iron grades in different countries and standards, however, most of grades have same requirements to the mechanical properties, especially to tensile strength.
  4. The prices and production for pedestal, foundation support castings - on Aug. 27, 2012
    Some customers want to use steel boards or cast steels to make metal bases, pedestal and foundation supports. But we prefer to use cast iron materials to produce them. Let us explain the advantages and prices.
