Rashtriya Ispat Nigam Limited, the corporate unit of Vizag Steel Supplierin Delhi is a Navaratna PSE under the Ministry of Steel. Visakhapatnam Steel Plant is reverently called Vizag Steel. It is the first edge-based Integrated Steel Plant in the country and is known for its quality products satisfying our clients. Vizag steel is the foremost brand in the infrastructure industry and it caters to the demands of multiple Industrial sectors. Vizag steel plant is the prime Steel factory to be authorized ISO 9001:2008 (currently 2k15)), ISO 14001:2004 (currently2k15), OHSAS 18001:2007 and ISO/IEC 27001:2013 Standards. Vizag Steel plant is also the first PSE to be validated ISO 50001:2011 - Energy Management Systems and has attained the CMMI Level 3 Certification for s/w advancement.
Quenching and Self Tempering (QST) imparts a combined microstructure ranging from a well-built, solid, tempered martensite in the covering layer to a refined, tough, ductile ferrite-pearlite in the core with an intervening portion in between. Exceptional rib contours for extraordinary adhesion with concrete. Central Projected regions are extensively more than the specified qualities of the IS1786 criterion.
VIZAG TMT bars have a distinctive blend of strength and ductility. It offers high tensile strength and flexibility to meet higher strength ratios that are always greater than 1.12. In normal bars, the increase in the yield strength of the bars is accompanied by the loss of per cent elongation. But in the case of VIZAG TMT bars, this loss is negligible and the per cent elongation values are comparatively higher than normally specified percentages in various International Standards. In Fe 500D grade rebars the UTS/YS ratio values are sustained at more than 1.15.
The tests carried out on the VIZAG TMT bars, indicate that no significant change of strength as a function of time occurs which could affect the uncompromising quality of these bars.
There is no existence of Eutectoid Carbides and pearlite colonies in Vizag TMT bars, and it is also free stresses because of tempering, presence of martensitic layer at the outer surface and formation of adherent scale film due to water quenching during rolling are the reasons for high corrosion resistance properties of Vizag reinforcement bars.
The tough outer layer and the ductile core of the VIZAG TMT bars results in excellent bendability. This coupled with high resistance to low-temperature brittle fracture, allows these bars to be bent, and are unbreakable around small diameter mandrels. In the reverse bend test, these bars also show extraordinary results. In the construction site, the situation arises where bars bent is left for a period in the best condition and then reverse bent. During the period between the first bend and the reverse bend, the bars may strain age. The loss of ductility due to strain ageing and strain imposed from the first bend may cause failure during rebending operations if the bars are not sufficiently ductile. Test results have shown that VIZAG TMT bars have defined bendability, endurance and rebending properties after ageing.
