Q245R Q345R Pressure Vessel Carbon Steel Plate Hot Rolled 6mm-200mm for Boiler Tank and Heat Exchanger Manufacturing
Q245R / Q345R Pressure Vessel Carbon Steel Plate — Boiler & Tank Grade
Our Q245R and Q345R pressure vessel quality carbon steel plates are manufactured to GB 713 (equivalent to ASME SA516 Gr60/70 and EN P265GH/P355GH) with 100% ultrasonic testing to ensure internal soundness. These plates are specifically engineered for pressure-containing equipment operating at elevated temperatures with guaranteed mechanical properties up to 400°C. Excellent weldability, superior notch toughness, and certified compliance make this the trusted material for Middle Eastern petrochemical storage tanks and reactors, Southeast Asian power plant boilers, and African industrial processing vessels.
Key Features
- 100% Ultrasonic Testing: Every plate undergoes full UT inspection to EN 10160 S2E3 or ASTM A578 Level C, guaranteeing freedom from laminations and internal defects critical for pressure integrity
- Guaranteed Elevated Temperature Properties: Tensile and yield strength tested and certified at design temperatures up to 400°C, essential for hot-wall vessel design calculations
- Superior Notch Toughness: Fine-grain killed steel with Charpy V-notch impact values guaranteed at 0°C (Q245R) or -20°C (Q345R), preventing brittle fracture in pressurized service
- Excellent Weldability: Controlled carbon equivalent and low sulfur/phosphorus content ensure sound weld joints with standard filler metals and procedures
- PED 2014/68/EU Compliant: Meets European Pressure Equipment Directive requirements for CE-marked pressure vessels exported to the EU market
