Quenching and Self Tempering (QST) imparts a composite micro structure ranging from a strong, tough, tempered martensite in the surface layer to a refined, tough, ductile ferrite-pearlite in the core with a intermediate structure in between. Superior rib design for excellent bonding with cement. Mean Projected Area much more than the specified values of the IS1786 standard.

Advantages ..of TMT (QST) Rebars of VSP Combination of high strength and high ductility VIZAG TMT bars have rare combination of high strength with excellent ductility. The tensile to yield strength ratios are always greater than 1.12. In normal bars, the increase in the yield strength of the bars is accompanied by the loss of percent elongation. But in the case of VIZAG TMT bars this loss is negligible and the percent elongation values are much higher than normally specified in various International Standards. In Fe 500D grade rebars the UTS/YS ratio values are maintained always at more than 1.15. Resistance to ageing 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 usefulness of these bars. Superior corrosion resistance The absence of Eutectoid Carbides and pearlite colonies in VIZAG TMT , absence of stresses because of tempering, presence of martensitic layer at the outside surface and formation of adherent scale film due to water quenching during rolling are the reasons for better corrosion resistance properties of these reinforcement bars.

Excellent bendability and workability The tough outer skin and the ductile core of the VIZAG TMT bars result in excellent bendability. This coupled with a high resistance to low temperature brittle fracture, allows these bars to be bent, without fear of failure around small diameter mandrels. In the reverse bend test, these bars also show good results. In the construction site, situation arises where bars bent are left for a period in the bent condition and then reverse bent. During period between the first bend and the reverse bend the bars may strain age. The loss of ductility due to strain ageing and due to 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 withstood successfully the bending, straightening and rebending tests after ageing. The bend tests carried out at VSP have shown that these bars could be bent even around smallest dia mandrel without causing any cracking

The only plant to adapt this technology (QST) for production of rebars from the design stage. Hence, the total extent of the superior technology could be harnessed. 120 metres length of the cooling bed available for self tempering which no other mill in India can match is the testimony for this.

Unmatched Strength

The Steel making and Rolling process perfected by Sumangala over decades ensures a uniformity and consistency of strength in every TMT bar.

Superior Workability

By optimizing the manufacturing process and ensuring the right chemistry, Sumangala Steel ensures that the bars are Bendable, Bondable, and Weldable.

Enhanced Ductility

TMT bars in concrete are not only about strength but about resilience as well. It’s not just about how hard it is, it’s about how hard a hit it can take and still bounce back. The superior ductility of Sumangala TMT bars ensures flexibility and enduring reliability.

Immutable Corrosion Resistance

Our secondary steel making process augments our TMT Bars with Copper, Chromium & Nickel, providing an added layer of corrosion resistance over virgin steel bars. This is vitally important in coastal regions with salinity.

Value for Weight

Close control of sectional tolerance of every TMT bar ensures that no more or no less than the necessary amount of steel is used.

Customized Lengths

TMT bars are usually manufactured in standard lengths of 40 feet (12.2 mtrs) and sold as both, straight and bent. Our modern mill has the ability to offer customized lengths as well.
