DYTRON TMT steel bars are manufactured by hot rolling through Quenching & Self Tempering (QST) process and not by cold twisting. DYTRON QST CRS is made using a specific combination of corrosion-resistant elements like Cu, P and Cr. The combination gives the bars a homogeneous microstructure of corrosion-resistant elements keeping the core and surface free from any torsional stress and thus slowing down the corrosion process. The best advantage of using DYTRON QST CRS is that there is no need for additional care to be taken during handling, fabrication and transporting. Chemical Properties Chart
