Per DIN 2391 and BIS IS 3601, the bands below are indicative precision tube prices for orders placed in May 2026, covering DIN 2391 (cold-drawn seamless) and IS 4923 (square/rectangular hollow sections). Precision tubes are cold-drawn from hot-rolled mother tubes to achieve tight OD/ID tolerances, smooth surface finish, and exact straightness — essential for hydraulic cylinders, instrumentation, and automotive applications.
All prices are per kilogram (₹/kg), ex-warehouse Kanpur, exclusive of GST (18%). For a firm delivered quote, submit your RFQ.

What Drives Precision Tube Pricing
Cold-Drawing Premium
Precision tubes undergo a secondary cold-drawing process after hot-rolling. This additional step (drawing through a die with or without a mandrel) is what delivers the tight OD tolerance (±0.1 mm) and smooth finish (Ra ≤ 1.6 µm). The extra processing adds 25–40% to the cost of a comparable seamless tube.
DIN 2391 vs IS 4923
DIN 2391 specifies cold-drawn seamless round tubes for hydraulic and pneumatic power systems. IS 4923 covers hollow sections (square, rectangular, circular) for structural and general engineering. DIN 2391 commands a significant premium due to tighter tolerances and the cold-drawn process.
Size & Wall Thickness
Smaller ODs (below 20 mm) carry higher per-kg costs because the drawing process becomes more labor-intensive and yields fewer meters per draw pass. Thicker walls use more steel but the per-kg price remains similar.
