Boiler and pressure vessel steel grades

High-quality boiler and pressure-vessel steel plates supplied for industrial fabrication, testing and export. Available in a broad range of commonly specified ASTM grades for boilers, pressure vessels, oil tanks, shipbuilding and petrochemical structures. Materials are supplied with mill test documentation and third-party approvals suitable for critical applications.

Key features:

• Wide selection of grades: A202 (A/B), A203 (A/B/D/E/F), A204 (A/B/C), A285 (A/B/C), A299 (A/B), A302 (A/B/C/D), A387 (Grades 5, 11, 12, 22 — Class 1 & 2), A515 (60/65/70), A516 Grade 70, A517 Grade B, A537 (Class 1 & 2) and equivalents. These cover carbon and alloy steels commonly specified for boilers and pressure vessels.
• Dimensions: thickness 6 mm to 150 mm; length 3,000 mm to 15,000 mm; width 1,500 mm to 4,050 mm. Custom cut-to-size options available.
• Heat treatment options: as-rolled, normalized, normalized + tempered (N+T), quenched and tempered (QT) — supplied per grade requirements and customer specification.
• Typical processing services: shot blasting, cutting, welding preparation, drilling, grinding and testing to customer drawings or standards.
• Quality and certification: original mill test certificates to EN 10204 3.1 / 3.2. Supplier holds ISO 9001 and offers approvals/inspection by SGS, BV, ABS where required.
• Minimum order quantity: 5 metric tons. Competitive factory pricing and export packaging for international shipment.

Applications:

• Boiler shells and headers
• Pressure vessels and reactors
• Oil and fuel storage tanks
• Shipbuilding structural plates
• Petrochemical and refinery equipment

Supply notes:

• Material selection and heat treatment should be confirmed against design codes and engineering specifications for pressure-bearing service. Buyers requiring witness testing, additional NDT (UT/RT/MT/PT) or bespoke traceability should specify at enquiry.
