Ductile casting is a kind of workpiece produced after nodular casting. This kind of workpiece has high strength after nodular casting, and its comprehensive degree can even be comparable to that of steel. In the case of complex stress, it can also guarantee strength, toughness and resistance The abrasiveness is very high. In the production of nodular cast iron bushings, the surface iron of the nodular cast iron needs to be removed.

On any surface, free iron will rust and corrode stainless steel. Therefore, it must be cleared. Floating powder can generally be removed with the dust. Some have strong adhesion and must be treated with embedded iron.

In addition to dust, there are many sources of surface iron, including ordinary carbon steel wire brush cleaning and shot blasting with sand, glass beads or other abrasives previously used on ordinary carbon steel, low alloy steel or cast iron parts, or Repair the non-stainless steel products mentioned above near the stainless steel parts and equipment. If the stainless steel is not protected during the cutting or lifting process, the steel wire, the spreader and the iron on the work surface are easy to embed or stain the surface.

Did you understand something? Ductile castings are a very useful product, and we must pay attention to these details during production to ensure quality.
