Satrang TMT Bar Properties
Finer Grain Structure:
Size reduction from ingots to the bars is done gradually in multiple stages for better and consistent grain structure. Refined and finer grain structure give better metallurgical properties to the bars for longer life.
Customized Product:
Chemical, metallurgical and physical properties as per design requirements of clients are given by Satrang Steels. Additional relevant services are offered as per specific customer requirements.
Bend Properties:
Satrang TMT bars have excellent bend properties due to the unique ductility (elongation values) obtained by employing the EAGLE-TMT/Q&T Technology.
Higher Strength:
Satrang TMT bars have high strength and are available in all the grades. So, now you can have high strength bars and thus can easily cut the overall costs by optimizing consumption.
Corrosion Resistance:
Controlled water-cooling prevents the formation of
coarse carbides, which has been cited as the main cause for the corrosive nature of common bar. Another reason for better corrosion resistance is the absence of surface stresses caused by the cold twisting (and Torsteel) process.
Perfect Roundness:
Satrang TMT bars have high strength and are available in all the grades. So, now you can have high strength bars and thus can easily cut the overall costs by optimizing consumption.
Weldability:
Satrang bars with carbon content less than 0.25% can be used for butt and other weld joints without reduction in strength at the joints.
Fire Resistance:
Unlike Tor steel and CTD Rebars, Satrang bars have high thermal stability. They are a preferred choice in case of elevated temperatures of 400 - 600° C applications (chimney, fires).
Higher Bonding Strength:
Satrang bars with their uniform and precise rib pattern ensure better bonding strength with concrete.This gives higher strength to the structure and hence a longer life.
Precise Gauge Control:
Gauge Control System ensures precise and accurate weight of the bars by controlling gauge of the bars automatically between stringent tolerances.
Formability:
Due to very high elongation values and consistent properties through out the length of bar, Satrang bars have excellent workability and bendability.
Strain Ageing:
Due to unique, scientific manufacturing process and chemical composition, Satrang bars show no tendency of brittleness either during welding or cold deformation of welded joints.
The use of EAGLE-TMT/Q&T (Quenching & Tempering Technology System), has enabled the production of these high strength re-bars.
Directly after the last rolling mill stand, the steel bar surface receives a short intensive water cooling as it passes through the System. The rapid temperature reduction of the bar periphery converts the surface layer of steel bar to a hardened structure.
