AST YST 240 Light Duty 65 NB MS Round Pipe - (3.2 x 76.2 mm) - 6 mtr Length is a Light Duty ERW mild steel round pipe manufactured from YST 240 steel fully conforming to IS 1239:2004 (Mild Steel Tubes, Tubulars, and Other Wrought Steel Fittings), delivering a minimum yield strength of 240 MPa and tensile strength of 360 MPa for medium-duty structural, industrial, and mechanical piping. The 3.2 mm wall × 76.2 mm OD (65 NB) cross-section in 6 m standard lengths features optimised wall thickness delivering cost-effective performance for low-pressure and light structural use, ensuring reliable dimensional accuracy and consistent mechanical performance across plumbing, structural, and general engineering installations. Produced by AST PIPES, each IS-certified tube carries full batch traceability and is designed for direct use in welded, threaded, and flanged connection systems.
