Tata Wiron ASTM A416-2010 Grade 1725 Round Strand

Tata Wiron ASTM A416-2010 Grade 1725 Round Strand is manufactured by Tata Wiron (Tata Steel) American-specification work that calls for the 1725 MPa grade, the metric equivalent of ASTM’s traditional Grade 250 designation.

Manufactured to ASTM A416-2010 (Round Strand), this strand delivers four sizes from 9.50 mm to 15.20 mm, minimum breaking loads of 89.0–240.2 kN and yield loads of 80.1–216.2 kN at 1% elongation, manufactured on plants certified to ISO 9001:2008 with in-house relaxation testing on every production lot.

Typical applications for the Tata Wiron ASTM A416-2010 Grade 1725 Round Strand include US-linked infrastructure work in the Middle East and Asia where ASTM A416 governs but the lower Grade 1725 capacity is sufficient for the tendon design.

Behind the Tata Wiron ASTM A416-2010 Grade 1725 Round Strand sits ISO 9001:2008 certified manufacturing at plants NABL-accredited to ISO/IEC 17025, with independent testing at EMPA Switzerland covering cryogenic tensile strength at –165°C, fatigue performance and one-pin bend behaviour before any coil is released for dispatch.

Before stressing, the Tata Wiron ASTM A416-2010 Grade 1725 Round Strand should be handled with care: cut only with an abrasive disc cutter or shear cutter, never with a flame or welding torch, since heat changes the steel’s microstructure and its mechanical properties. Coils should be unloaded with a crane rather than dropped off the vehicle, stored under cover on a raised platform away from direct ground or water contact, and protected with a vapour phase inhibitor if they will sit on site for an extended period before stressing.
