Manganese‑molybdenum alloy steel plate engineered for welded boilers and pressure-vessel fabrication. Conforming to ASME SA302 Grade A (A302 A), the plate is supplied as a fully killed steel with enhanced mechanical strength and toughness for high‑temperature, high‑pressure service.
Key mechanical properties
- Minimum yield strength: 310 MPa
- Tensile strength: 515–655 MPa
Standards & compliance
- ASME SA302 Grade A (A302 A)
- Original mill test certificate issued under EN 10204
Quality control & available tests/services
- High-tension (tensile) testing
- Low-temperature impact testing
- Normalizing for plates thicker than 40 mm
- Simulated post-weld heat treatment (PWHT)
- Rolling to NACE MR0175 requirements where required (HIC + SSCC)
- Cutting, shot blasting, painting and welding to end-user specifications
Typical applications
- Industrial and utility boilers
- Pressure vessels and heat-exchangers
- Heavy fabrications where high strength and post-weld performance are required
- Marine and shipbuilding structural components, where alloy performance is needed
Supply options
Plates can be supplied with full traceability documentation (mill test certificate) and processed (cut-to-size, surface preparation, painting or welding) per purchaser requirements. Contact your supplier to confirm available thicknesses, plate sizes and lead times.
