THE TECHNOLOGY BEHIND THE TRUSTWORTHY RE-BARS
EMSON QT re-bars are rolled out using one of the most recognized and worldwide trusted TEMPCORE PROCESS.The QT re-bars are quenched to red-hot rolled steel immediately after the last stage of hot rolling. A hard and strong martensitic outer casting is formed, which the internal heat of the bar tempers to some extent, while the centre cools more slowly to form a softer more ductile Ferrite/Pearlite core. This is Quench and Self Tempered (QST) process & is the combination of high strength and ductile core working in conjunction with one another, which provides the mechanical properties as stipulated by ISI and International Standards.
