High-strength molybdenum-alloy steel plates manufactured to ASTM A204 Grade C requirements. These plates are specified for welded boiler and pressure-vessel applications where elevated temperature strength is required. Grade C offers the highest strength (and comparatively lower ductility) among the A204 grades and is supplied in the as-fabricated condition unless further heat treatment is specified.
Key specifications
- Standard: ASTM A204, Grade C
- Material type: Molybdenum-alloy steel, intended for welded boilers and pressure equipment
- Thickness (range): 3 mm to 300 mm (typical supply range; confirm availability per order)
- Widths (typical): 1500 mm, 2000 mm, 2500 mm, 3000 mm
- Lengths (typical): 6000 mm, 12000 mm
- Supply form: Plates / sheets, hot-rolled (specify coil or cut plates at time of order)
Typical applications
- Welded boilers and pressure vessels
- Heat exchangers and high-temperature pressure parts
- Petrochemical and power-generation equipment
Quality, testing and supply options
- Supplied to ASTM A204 Grade C chemical and mechanical requirements
- Mill test certificates (MTR/MTC) and material traceability available on request
- Plates can be supplied cut-to-size, edge-prepared, and packaged for export
Handling and fabrication notes
- Grade C is a higher-strength, lower-ductility alloy compared with other A204 grades; follow appropriate fabrication and welding procedures for alloy steels
- Preheat and welding consumable selection should follow applicable codes and project specifications
Ordering information
Please specify required thickness, width, length, surface finish, required certificates (MTC, PMI, NDT) and any special processing (cutting, edge prep, heat treatment) when requesting a quotation. Lead times and minimum order quantities depend on plate size and processing requirements.
