EN 10216-1 P265TR1 Seamless Pipes & Tubes

If you are looking for the higher strength option within EN 10216-1, P265TR1 is the grade to consider. These seamless pipes and tubes use steel number 1.0258 and have a minimum yield strength of 265 MPa, with tensile strength ranging from 410 to 570 MPa. P265TR1 replaced the older DIN 1629 St 44.0 designation, so the grade may also come up on projects based on earlier German specifications. Amardeep Steel supplies EN 10216-1 P265TR1 seamless pipes and tubes with EN 10204 3.1 mill test certificates and full heat traceability. Where impact testing is required, see our EN 10216-1 P265TR2 seamless pipes. For elevated temperature service, see EN 10216-2 P265GH tubes, or browse all carbon steel seamless pipes and tubes.

What Are EN 10216-1 P265TR1 Seamless Pipes & Tubes?

P265TR1 is a non-alloy steel for seamless pressure tubes with properties specified at room temperature. Higher carbon (0.20% maximum) and manganese (1.40% maximum) than P235 lift the yield to 265 MPa, so thinner walls can carry the same pressure. As a TR1 quality, it has no aluminium requirement and no mandatory impact test.

P265TR1 or P265GH?

Both grades have 265 MPa minimum yield, but P265GH is made to EN 10216-2 with yield values specified at elevated temperatures for boilers and pressure vessels. P265TR1 has properties specified at room temperature only. Use P265GH wherever the design temperature is above ambient.

Applications of P265TR1 Seamless Tubes and Pipes 

• Water, air and gas pressure lines
• Compressed air and pneumatic systems
• Mechanical and structural pressure parts
• Higher pressure water and hydraulic lines
• Machine building and replacement of St 44.0 tubes

Testing and Documentation

Every order of P265TR1 seamless tube goes through the checks below at our testing facility or approved third party labs.

• Ladle chemical analysis
• Tensile test
• Flattening or ring expanding test
• Leak tightness test: hydrostatic or electromagnetic
• Visual and dimensional inspection

Mill test certificates are issued to EN 10204 3.1, with 3.2 available on request. You can view our approvals on the certificates page.

Packing and Marking

Each tube is marked with EN 10216-1, P265TR1, size, heat number and manufacturer name. Tubes are varnished or oiled against rust, ends capped on request, and packed in hexagonal bundles with steel strapping. Read more about our packing and despatch process.
