What is P265TR2?
P265TR2 (1.0259) is the fine-grain-practice version of P265TR1, a low-carbon (≤0.20 % C) non-alloy tube steel with improved toughness and weldability at the same strength level: 300 MPa yield, 470 MPa tensile, 25 % elongation and about 130 HB. It is specified for precision seamless and welded tube where verified impact performance at lower temperatures is required, in +N, +AR, +C, +LC, +SR and +A conditions. Like all plain carbon tube steels it needs a coating for corrosion protection; where impact testing is not required, P265TR1 is the cheaper equivalent. P265TR2 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,495°C (2,723 °F). P265TR2 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 25% and the elastic modulus is 210 GPa (30.5 Msi).

Working with P265TR2
Is P265TR2 easy to machine?
Machines like 1018/1020 — use sharp positive-rake tools and generous feed to avoid built-up edge and gummy chips; cold-drawn (+C) condition cuts and chips more cleanly than annealed.
Can P265TR2 be welded?
Excellent weldability with SMAW/GTAW/GMAW/SAW using E7018 or ER70S-6 class filler; CEV ≤ 0.40 means no preheat below ~20 mm, keep interpass moderate to preserve fine-grain toughness.
Can P265TR2 be formed, bent or molded?
Cold bends to about 2–3×D in +N or +A condition and passes the standard flattening/flaring tests; hot form at 850–1000 °C followed by renormalizing to restore TR2 impact values.
