Key Features of Satya TMT Bars

In summary, the combination of a hardened surface and a softer core achieved through the two-phase cooling process in Thermex® technology results in TMT bars with superior properties in terms of strength, toughness, ductility, and weldability. These properties make them an excellent choice for use in infrastructure and high-rise residential construction, where structural integrity and reliability are paramount.

Superior Strength

Satya TMT bars are rolled out in modern Rolling Mill equipped with computerized controls. Every critical parameter is continuously monitored to deliver with the best quality having higher stress strain ratio along with same yield strength. The high strength of the bars make them an ideal material to be used with concrete for making structures more robust. The ductility of the TMT bars makes them easier to work with, and pre-welded meshes can be made offsite reducing the overall construction time.

Seismic Activity

Satya TMT bars have the ability to absorb large amount of energy and shock released during earthquakes / seismic activities thus avoiding catastrophe. The high elongation and ductility and can thus be deformed to a much larger extent without breaking. A combination of very specific balance of chemical properties and stringent quenching parameters develops the desired parameters.

Superior Bendability

Ductility determines the capacity of bending. Satya TMT bars are having a tough outer surface with a soft core thus increasing bendability, also making it suitable to adapt to architectural design as desired allows for easy working.

Superior Weldability

Satya TMT bars have do not require pre or post welding treatment asthey have low carbon content and are produced under controlled Thermo Mechanical Treatment .

Superior Bonding

Satya TMT bars have been designed with uniform and precise rib pattern to ensure excellent bond strength between mortar, concrete & reinforcement steel.

Fire Resistance

Satya TMT bars have high thermal stability and can withstand higher temperatures ensuring safety. Due to its high thermal stability, TMT bars can withstand temperatures ranging from 400 to 600 degree Celsius; this ensures the building’s structural integrity even during a fire.

Cost Saving

Due to superior strength & elongation of Satya TMT bars, lesser quantity than ordinary TMT bars are required. This indirectly helps for savings without affecting safety & quality. Apart from reducing the cost of raw material, it also saves cost on transportation and storage. Satya TMT bars are also easier to manage on-site, which leads to a further cost saving due to reduced construction and fabrication time.

M/s HENNINGSDORFER STAHL ENGINEERING GmbH's Thermex® technology for quenching and tempering TMT (Thermo-Mechanically Treated) bars is designed to provide superior uniformity in the properties of these bars, making them ideal for use in infrastructure and high-rise residential constructions. The unique properties of TMT bars produced using Thermex® technology are achieved through a two-phase cooling process that results in a distinct difference between the peripheral layer and the core of the TMT bar.

In the first phase of the cooling process, the TMT bar is subjected to intensive cooling in the Thermex Water Cooling system. This rapid cooling of the surface leads to the formation of a martensite zone in the outer layer of the bar. Martensite is a very hard and strong phase of steel, contributing to the surface's hardness and strength.

The second phase involves a slower cooling process where the core of the TMT bar is cooled over an extended period in the open air. This gradual cooling allows a ferrite-pearlite structure to form in the core of the bar. Ferrite-pearlite is a combination of two microstructures that provide the steel with better bendability while maintaining its strength.

The key benefits of this two-phase cooling process in Thermex® technology are:

Uniformity in Strength: The combination of a hardened surface and a softer core ensures that the TMT bars have uniform strength properties throughout their cross-section. This uniformity is crucial for structural integrity in construction.

Toughness: The martensitic surface provides toughness and resistance to wear and tear, making the TMT bars durable in demanding construction applications.

Ductility: The ferrite-pearlite core contributes to the ductility of the TMT bars, making them more flexible and able to withstand bending without breaking.
