Casting as an alternative to fabrication in corrosive environments
Described by the customer as a “fabrication nightmare” the mating components in pulp dewatering systems present a difficult manufacturing challenge. The grids operate in a pulp and paper environment that demands the corrosion-resistant qualities of nickel-based alloys like those in the Monel®family. These alloys provide superior corrosion resistance, but with their strength comes hardness that makes further processing and machining more difficult than many other alloys. Customers rely on MetalTek’s ability to provide components very close to the required net shape in these demanding alloy grades. By casting in the grates and fins, MetalTek’s customers avoid fabrication welds, and a tightly controlled manufacturing process solves a mating part challenge as well.
