Conforming to IS 1786:2008 Grade Fe 415, the Spark TMT Bar Spark Fe 415 TMT Bar - 8 mm is a thermomechanically treated reinforcing bar in 8 mm diameter, supplied in standard 12 m lengths. The QST process imparts a hard tempered outer zone and a ductile core, achieving 415 MPa yield, 485 MPa UTS, and 14.5% elongation for reliable use in general construction, residential slabs, and low-rise structural concrete. The superior weldability, corrosion resistance, and bond characteristics of this TMT bar make it the preferred reinforcing steel for structural concrete across residential, commercial, and infrastructure applications.
