Tuolian Alloy 31 Plate
Alloy 31 (1.4562) in plate form has a smooth, flat surface with uniform thickness. They are available from 3 mm to 50 mm. And it comes with standard widths of 1000 mm or 1219 mm. But, Tuolian can offer custom sizes or thicknesses upon your request.
Heat exchangers, reactors, tanks, piping systems, dairy processing equipment, flue gas desulfurization systems, scrubbers, bleach plant components, digester vessels, black liquor recovery boilers, offshore oil rig platforms, ore extractors, oil and gas pipelines, processing equipment are the common alloy 31 application.
In terms of the production process, the UNS N08031 plate can be formed by hot rolling or cold rolling processes. Plus, it can be further processed to achieve specific surface finishes or tolerances. At Tuolian, we can provide customized solutions to meet your unique requirements.
