Home Jindal TMT 500 HD - Features & Advantage

Key Features & Advantage

EASY BENDABLITY
JINDAL TMT 500 HD can be bending into customized shape in spite of having very high strength due to its inherent microstructure with soft ferrite and pearlier core.

HIGH DUCTILE
JINDAL TMT 500 HD has new Power of High Ductility. Jindal bars are crafted under strictly reglated manufacturing process which makes them easily bendable. There is an important connection between concrete and steel. Concrete has great compressive power but relatively low tensile strength and ductility, therefore when it fuses with TMT steel bars; it gives rise to a highly ductile and tensile combination.

EARTHQUAKE RESISTANCE
JINDAL TMT 500 HD is specially designed for seismic zones and has more resistance to earthquake & shock due to combination of higher strength & ductility. Its high UTS/YS ration of 1.15 minimum ensure higher energy absorption capacity

HIGHER STRENGTH
jindal tmt 500hd is toughened high stress and made by High Yield Quenched & self tempered process, Which ensuring grade of 500.

BOND STRENGTH WITH CONCRETE
JINDAL TMT 500 HD is excellent in cyclic loading situation due to uniform & critically designed rib pattern. Rib gives the more solid bonding with concrete.

Easy Weldability
JINDAL TMT 500 HD has excellent weldability due to lower carbon equivalent. It can be easily butt-welded, lap-welded and manual arc welding can also be done quite simply without any pre-heating.

CORROSION RESISTANCE
JINDAL TMT 500 HD has higher corrosion resistance as compared to ordinary rebar’s due to its unique & uniform microstructure and absence of residual stresses.

PRODUCTION AT A GLANCE

1. Process route of Furnace steel making - Ladle Refining Continuous Casting of Billets ensure the right 7 desired quality with minimal tramp elements & Sulphar & Phosphorus content of 0.075 % Max. Cast Billet are hot rolled in Automatic coiling mill, Which ensure uniform dimensions & properties in each bar.

2. Surface finish of each bar is excellent as the mill employs tungsten carbide rolls against conventional rolls. Each bar is thermo mechanically treated. After leaving the last stand of the rolling mill, the bars are quenched (rapid coiling) in water from final rolling temp of about 1050*c. The Quenching is partial, only until outer surface layer has been transformed from austenite to marten site

3. Because of partial quenching, a part of the original heat remains in the core of the steel and on the coiling bed, this migrate towards the surface and result in an automatic self tempering process where the surface layer of marten site is tempered. The resulting tempered-marten site shows improved deformability compared to as quenched marten site.

4. On atmospheric cooling on cooling bed, Austenitic core is transformed into ductile ferrite - pearlier. ¬¬¬The core of the heat treated bars consits of ferrite & pearlier while strong outer layer consits of marten site.
