Alloy 825 plate is selected for equipment exposed to aggressive process fluids. Your engineering team can confirm compatibility with the specified operating conditions.
Plate for fabricated process vessels, tanks and associated acid-processing equipment.
Nickel alloy plate for equipment exposed to designated acid-cleaning and regeneration streams.
Plates formed and welded to the specified equipment design and corrosion service.
Plates for components serving sulfuric- and phosphoric-acid process systems.
Corrosion-resistant fabricated parts for selected wet-gas and pollution-control systems.
Plate components for heat-exchange equipment and adjacent process structures.
Specified components for oil and gas equipment subject to appropriate service qualification.
Plate parts for plant maintenance, processing equipment and retrofit projects.
Source plate by heat-treated condition, flat dimensions and drawing requirements. Include the material certificate type and any additional corrosion-service acceptance criteria in your RFQ.
Enter your plate dimensions and quantity to estimate nominal weight using Alloy 825 density of 8.14 g/cm³.
Nominal mass estimate based on 8,140 kg/m³; actual supplied and invoiced weight follows the agreed tolerance and weighing terms.
Theoretical weight helps you prepare a material list and freight estimate. Your final quote can reflect grade, finished dimensions, material condition, documents and shipment terms.
