In very high heat transfer rate applications, such as continuous caster mold cooling systems, chromate levels should be maintained at 100-150 ppm maximum. Under these extreme conditions, chromate can accumulate at the grain boundaries on the mold, causing enough insulation to create equipment reliability problems.
pH of the water must be maintained below 9.0.Corrosion rate accelerates at pH levels higher than 9.0 for Cu.
