Overview
P265GH TC2 is a seamless steel pipe material for high-temperature pressure-bearing applications that complies with the European standard EN 10216-2. It is a non-alloy steel specifically designed for boilers, pressure vessels, heat exchangers, and high-temperature piping systems. This material features excellent high-temperature strength, weldability, and heat resistance, making it suitable for industrial environments with high operating temperatures.
Standards and Specifications
Main Standard: EN 10216-2 (equivalent to ISO 9328-2)
Applicable Specifications: PED (Pressure Equipment Directive of the European Union), ASME (partial application)
Test Category: TC2 (Test Category 2), representing more stringent inspection requirements

Requirement 410 – 530 ≥ 265 ≥ 24 -20 (KV ≥ 27J)
Main application fields
P265GH TC2 is mainly used in the manufacturing of equipment under high-temperature and high-pressure conditions, including:
Boilers and pressure vessels (such as power station boilers, industrial boilers)
Petrochemical pipelines (high-temperature oil and gas transportation)
Heat exchangers and steam pipelines
Nuclear power and energy industries (auxiliary system pipelines)
Advantages and Features
High-temperature stability – Can be used for a long time at temperatures below 400°C
Good weldability – Suitable for TIG, MIG, submerged arc welding and other processes
Strict quality control – TC2 grade requires higher non-destructive testing (UT, RT, etc.)
Compliance with international standards – Applicable to the EU and global markets
Relevant comparative materials:
Chinese standard: 12CrMoG (GB 5310)
American standard: SA-106 Gr.B (similar application)
German standard: DIN 17175 (partial overlap)
