High-strength ASTM A299 Grade A carbon steel plate engineered for welded boilers, pressure vessels and other high-pressure, high-temperature applications. Manufactured to the ASTM A299 Grade A specification, these plates deliver the mechanical properties and fracture-toughness required for pressure equipment while offering wide dimensional options and on-demand inspection services.
Key features
- Typical dimensions available: thickness 3–150 mm, width 1,220–4,200 mm, length 5,000–18,000 mm
- Grade behavior: specified minimum yield strength is reduced for plate thicknesses over 1 in (25 mm), per the ASTM A299 specification
- Suitable for fabrication into welded boilers, pressure vessels, tanks and similar pressure-retaining components
Quality assurance & testing (available on request)
- Chemical composition analysis (mill and independent testing)
- Tensile (room-temperature and high-temperature) and additional tension testing
- Charpy V-Notch impact testing for toughness assessment
- Drop-weight testing
- Ultrasonic examination (UT) for internal flaw detection
- Magnetic particle inspection (MPI) for surface and near-surface discontinuities
- Dimensional inspection and certification; mill test reports (MTRs) available
Fabrication & services
- Cut-to-size, sawing and thermal cutting
- Machining and edge preparation to customer specifications
- Supplied with independent, accredited and regularly audited quality control and inspection procedures
- Stock availability and export-ready packaging for bulk orders
Use this material where reliable strength, toughness and consistent chemistry are required for pressure-retaining components. For quotation, lead times, available certifications (MTRs, inspection reports) and custom processing options, request detailed supply terms and test certificates from the seller.
