Jindal 500D

Jindal

Overview

When it comes to talking about steel, JINDAL is an undoubted leader! It is a name that needs no introduction! The company made its foray into the business of manufacturing and trading steel pipes in a village in Haryana in 1952. Soon after, it started manufacturing steel pipes, sockets, and bends in West Bengal and within a decade had multiple units throughout India manufacturing various Steel Products. Bhuleshwar Steel is associated with Jindal as an ‘Authorized Conversion Agent’.

Features

Each of the JINDAL 500D bars are specifically designed keeping in mind the requirements of strength. Every 500 TMT is loaded with the following advantages:

  • It is Earthquake Resistant because the Tempered Martensite ring imparts strength to the structure whereas Martensite + Ferrite band gives the ‘Sping effect’ which tends to restore the original shape when the applied stresses are removed.
  • A unique combination of Carbon & Manganese maintaining the right C. E. and absence of any torsional residual stresses in the bar Delays Rusting.
  • It has more Strength to sustain Fire, it would not distort up to temp. of 500-600 Cº
  • JINDAL TMT Bars bond strongly with cement than other reinforcement bars as it has a unique rib pattern in terms of greater rib depth and closer rib spacing, which ensures excellent bonding with concrete in a reinforced structure.
  • A high yield strength of 450 N/mm2 as compared to ordinary TMT bars which have 418 N/mm2.
  • High Bendability and Ductility.

MANUFACTURING PROCESS

Thermo-Mechanical Treatment (TMT) is a metallurgical process that integrates work hardening and heat-treatment into a single process. Fully automatic PLC based machines maintain the temperature during the rolling process. After the last rolling stand, the billet moves through a quench box. The quenching converts the billet’s surface layer to Martensite and causes it to shrink. The shrinkage pressurizes the core, Helping to form the correct crystal structures. The care remains hot and Austenitic. A microprocessor controls the water ow to the quench box, to manage the temperature difference through the cross-section of the bars. The correct temperature difference assures that all processes occur and bars have the necessary mechanical properties. The bar leaves the quench box with a temperature gradient through its cross section. As the bar cools, heat ows from the bar’s centre to its surface so that the bar’s heat and pressure correctly tempers an intermediate ring of Martensite and Bainite. Finally, the slow cooling after quenching automatically tempers the austenitic core to Ferrite and Pearlite on the cooling bed. These bars therefore exhibit a variation in microstructure in their cross section, having strong, tough, tempered Martensite in the surface layer of the bar, an intermediate layer of Martensite and Bainite and a rened, tough and ductile Ferrite and Pearlite care.

When the cut end of TMT Bars is etched with Nital (Mixture of Nitric acid & Methanol), three distinct rings appear. 1. Tempered outer of Martensite. 2. A semi-tempered ring of Martensite & Bainite and 3. A mild circular ring of Pearlite & Ferrite This is the desired micro-stricture for a Quality Construction Rebar.
