The high-chromium coating (suitable for high-chromium, high-nickel, and carbon steel) features high drying strength. It has no cracking, good adhesion, high high-temperature strength, high shell removal rate, and ensures good casting finish. Thus, the quality of castings is no longer affected by evaporative pattern coatings. Meanwhile, it has excellent high-temperature resistance, which can effectively prevent mold collapse, thereby significantly reducing various casting defects and improving the yield rate.
