Cast iron

Sherardizing is extremely suitable for the protection of castings and ironwork made from special alloys. Diffusion galvanizing is used to apply a controlled and uniformly thick coating. Sherardizing makes it impossible for the zinc coating to expand uncontrollably (Sandelin effect).

The gradual warming of products during the sherardizing process does not add internal stresses to the base material. This is important in the case of heavy castings with different wall thicknesses.

Sherardizing produces a uniform coating on the entire product surface. Sherardizing excludes the risk of ungalvanized areas in shrink cavities, as can happen in the case of hot-dip and electrolytic galvanizing.

Sherardized castings of different compositions varying in weight from a couple of grams to more than 100 kg per item are frequently used in various industries.
