A387 GR11CL1 and GR11CL2 are chrome-molybdenum alloy steel plates engineered for high-temperature and high-pressure service in boilers and pressure vessels. This grade uses a 2.25% chromium-1% molybdenum composition, conforming to ASTM A387/A387M standards. The material is supplied in industrial thicknesses from 6 mm to 150 mm, with standard sheet dimensions of 1500x6000 mm and 2000x12000 mm, suitable for large-scale fabrication projects.
The alloy composition provides elevated temperature tensile and yield strength, with typical creep resistance exceeding 1% at 500°C for prolonged service. Chrome-moly plates resist hydrogen attack and thermal shock, making them a standard choice for power plant, refinery, and petrochemical infrastructure. The material is normally supplied in the normalised and tempered condition, with ultrasonic testing and charpy V-notch impact tests conducted as standard for Class 1 and Class 2 variants.
Primary buyers include fabrication yards and engineering contractors serving the energy sector, where these plates form critical components for boilers, reactors, and heat exchangers. The product is classified under HS 7225 for export, enabling streamlined customs clearance for international shipments. Buyers typically confirm Incoterms such as FOB Qingdao or CIF destination port, with packaging in steel crates or bundled pallets to prevent transit damage.

Before ordering, verify the plate thickness, sheet dimensions, and heat treatment condition to match your project specifications. Confirm that the supplier can provide mill test certificates and third-party inspection reports for each batch, as these documents are critical for compliance with industry standards such as ASTM A387.
Clarify logistics details, including packaging standards (steel crates or bundled pallets), Incoterms (FOB or CIF), and lead times for bulk orders. Port of loading and destination port should be agreed upon to avoid delays, and ensure the supplier can handle export documentation under HS code 7225 for smooth customs clearance.
Conduct quality checks upon delivery, including visual inspection for surface defects and dimensional verification. Request additional tests such as ultrasonic examination or hardness testing if your application demands stricter tolerances. Ensure all documentation, including material traceability and test results, is provided for audit purposes.
