Detail Information

Steel Sand Casting Manufacturer from China with Custom and CNC Machining Services.

Cast steel refers to the steel used for the manufacture of steel castings. Cast steel should be used when the strength of the casting is relatively high and the use of cast iron cannot meet the requirements. However, the fluidity of molten steel of cast steel is not as good as that of cast iron, so the thickness of the pouring structure should not be too small and the shape should not be too complicated. When the silicon content is controlled at the upper limit, the fluidity of molten steel can be improved. 

Raw Materials Available for Sand Casting 
  • Casting tool steel. Cast tool steel can be divided into casting tool steel and casting mold steel.
  • Casting special steel. Casting special steel can be divided into cast stainless steel, cast heat-resistant steel, cast wear-resistant steel, cast nickel-based alloy, etc.
  • Cast steel for engineering and structure. Cast steel for engineering and structure can be divided into cast carbon structural steel and cast alloy structural steel.
  • Cast alloy steel. It can be divided into cast low alloy steel, cast medium alloy steel and cast high alloy steel.
  • Gray Cast Iron: GJL-100, GJL-150, GJL-200, GJL-250, GJL-300, GJL-350
