Jindal Panther TMT Rebars are manufactured from virgin iron ore through a unique iron making, steel making & rolling process, which makes them stronger, safer and more ductile than any other TMT rebars, thus ensuring superior and consistent quality for each
length of the bar. The advanced HYQST /QST used in manufacturing results in strong and tough Martensite on the surface layer of the bar, an intermediate layer of Martensite and Bainite, and the core attains a soft Ferrite and Pearlite microstructure for a unique combination of strength and ductility.
Low levels of carbon ensure easier and faster welding without preheating. This means stronger and safer weld joints & reduction in wastage during welding at site.
Jindal Panther TMT Rebars have precise, uniform and parallel rib pattern engraved through computer controlled notch making machines, resulting in excellent bond strength with concrete. Parallel ribs on Jindal Panther TMT Rebars are produced by a high
-speed finishing block called NTM (No Twist Mill) which is an ultra-heavy-duty block using Tungsten Carbide rings that impart close dimensional tolerance with superior surface finish.
Jindal Panther TMT Rebars have been proven to have higher resistance to cyclic loading conditions and are recommended in the earthquake prone areas due to their superior seismic resistant properties. Jindal Panther TMT Rebars meet international specifications
for the UTS/YS ratio thereby providing them with high strength and high ductility. High UTS/YS ratio and more percentage elongation signify that the steel is capable to strain harder, in the event of an earthquake.
Due to the highly controlled process that ensures a microstructure with a soft (Ferrite and Pearlite) core. Jindal Panther TMT Rebars have excellent bendability (in spite of their high strength) facilitating easy bending, making work easier and faster at the construction sites.
Steel in concrete is usually in a non-corroding, passive condition. However, when corrosive elements like chloride from the sea water, soil salinity or carbon, nitrogen oxide from atmospheric pollution enters concrete, they disrupt the passive layer protecting the steel, causing rust and leading to a
loss of bond between the steel and the concrete. The parallel rib pattern in Jindal Panther TMT Rebars created in the final finishing stand eliminates the chance of torsion residual stress. This coupled with low carbon content leads to superior corrosion resistant properties as compared to the ordinary rebars.
The quenching and the self-tempering treatment at a temperature of approximately 650°C results in a consistent and thick layer of tempered Martensitic-ring on the outer surface of the rebar imparting higher capacity to retain strength at elevated temperatures.
