What is P265TR1?
P265TR1 (1.0258) is a non-alloy low-carbon steel (≤0.20 % C) from the EN pressure- and precision-tube family, supplied as-rolled, normalized (+N), cold-drawn (+C), stress-relieved (+SR), annealed (+A) or lightly cold-worked (+LC). Engineers choose it over P235TR2 when a higher strength level is needed in seamless and welded precision tube, with typical values of 300 MPa yield, 470 MPa tensile, 26 % elongation and about 130 HB. It has no inherent corrosion resistance and is limited to roughly 300 °C service; where verified low-temperature impact properties are required, specify P265TR2 instead. P265TR1 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,460°C (2,660 °F). P265TR1 has a yield strength of 300 MPa (43.5 ksi) and a tensile strength of 470 MPa (68.2 ksi) — weaker than 86% of steel grades. Elongation at break is 26% and the elastic modulus is 210 GPa (30.5 Msi).

Working with P265TR1
Is P265TR1 easy to machine?
Free machining at HSS/carbide speeds but gummy in the annealed state — use positive rake, sharp edges and good chip breakers; cold-drawn (+C) condition gives the best surface finish.
Can P265TR1 be welded?
Excellent weldability by all common processes (GTAW/GMAW/SAW/HFI) with CEV ≈ 0.35–0.40; no preheat for wall thicknesses below ~25 mm, use low-hydrogen consumables (e.g. G3Si1 / E7018).
Can P265TR1 be formed, bent or molded?
Cold bends to about 2–3×D in +N/+A condition; use +SR or +A for flaring, expanding and tight bends, and normalize after heavy cold work if pressure service is required.
