Pulp and Paper Industry

In the pulp and paper industry, 304 or 304L stainless steel clad plates bonded with Q245R or Q345R are commonly used in black liquor evaporators, washing towers, bleaching vessels, and chemical recovery equipment. These materials provide sufficient corrosion resistance to alkali solutions and sulfide-rich media, while offering excellent weldability and mechanical strength. Clad plates extend the service life of pressure vessels and reduce overall maintenance costs in harsh wet and alkaline conditions.
