8% TOR and 12% TMT
TMT stands for Thermo Mechanically Treated steel. Thermo mechanically treated steel known as TMT steel can be described as a new-generation-high-strength steel having superior properties such as weldability, strength, ductility and bendability meeting highest quality standards at international level.
TMT means Thermo mechanically treated steel its a new-generation-high-strength steel having superior properties such as weldability, strength, ductility and bendability meeting highest quality standards at international level..thanks Aarif

Thermo Mechanically Treated (TMT) bars have revolutionised the industry with its superior quality as against the cold twisting process to manufacture the traditional reinforcement bars. The special heat treatment process ensures greater strength, excellent ductility, enhanced bendability and much superior weldability. CHEMICAL PROPERTIES : Grade C%Max* S%Max P%Max Mn%Min Si%Max Fe-415 0.30 .055 .055 .55 .35 The most commonly used steel bar for concrete reinforcement is TOR steel. The other names of TOR steel are CTD bar, deformed steel bar, twisted steel bar, HSD bar, CWD bar etc. These TOR steel bars can be used for general concrete reinforcement in buildings, roads, bridges etc. These steel bars process a combination of strength and ductility that is far in excess of minimum limits specified in standard IS:1786. ::TOR steel bars are certified to IS:1786 in dimensional tolerances. However in the size range of 8/12 mm where tolerance are of great concern, much closer tolerance that the specification is maintained. HYSD High Yield Strength Deformed (steel) .It is reinfrocement steel.
10 mm steel tmt of 100m weighs 62 kg and 8 mm tmt steel of 100 m weighs 39 kg
One type of steel is worked when cold, and the other is treated when hot.TOR steel is technically a brand name for reinforcing steel from Toristeg Steel of Luxembourg.TOR has become a verbal shortcut for any type of CTD (Cold Twisted Deformed) steel. It is one form of HYSD (High Yield Strength Deformed) steel.TMT steel bar is a newer variety of steel for construction purposes. For many years TOR Steel has been used for concrete reinforcement. Thermo Mechanically Treated bars (TMT bars) give you several advantages over the other types of steel:Twisting operation is not involved in the production of the TMT steel bar,so no residual stresses involved in that , which in turn increases the corrosion resistance.Rust and Corrosion Resistance :The main reason for failure in any reinforcement concrete structure is due to corrosion of TOR Steel in the concrete, where this steel corrodes in existence of chloride ions. TMT Bars, due to its Thermo- mechanical treatment are very highly rust and corrosion resistant and is best suited in the humid and coastal states like West Bengal and Orissa.Uses:TMT Bars are much superior to conventional TOR Steel by virtue of their various engineering properties and can be used for Residential Buildings, Bridges, Drums, Industrial Establishment and all types of concrete reinforcement purposes.TMT Bars:Grade - Fe 415IS: 1786Note:The project designers use thermo mechanically treated bars (TMT) in place of torsteel and even in TMT, the choice is increasingly focused on that with higher tensile strength ( Fe-500 in lieu of Fe-415) and high corrosion resistant TMT (HCRM) which is specially meant for use in coastal areas.

TMT 500 and TMT 500D bars are both types of Thermo-Mechanically Treated (TMT) steel bars with high tensile strength, commonly used in construction projects. However, there are differences between the two in terms of their manufacturing process and properties: 1. Manufacturing Process: TMT 500: TMT 500 bars undergo a standard thermo-mechanical treatment process involving controlled heating and rapid quenching, followed by self-tempering to achieve the desired mechanical properties. This process imparts the bars with high tensile strength and ductility. TMT 500D: TMT 500D bars undergo an additional process known as Direct Quenching and Tempering (DQT), which involves a more controlled quenching process followed by subsequent tempering. This additional step enhances the ductility and weldability of the bars while maintaining their high tensile strength. 2. Properties: TMT 500: TMT 500 bars typically have a minimum yield strength of 500 megapascals (MPa) and offer excellent tensile strength and ductility. They are suitable for a wide range of construction applications, including residential buildings, bridges, and commercial structures. TMT 500D: TMT 500D bars also have a minimum yield strength of 500 MPa but exhibit improved ductility and weldability compared to TMT 500 bars due to the additional DQT process. This makes them particularly suitable for structures requiring higher levels of seismic resistance and for applications where welding is necessary, such as in pre-fabricated structures or reinforcement in concrete. 3. Applications: Both TMT 500 and TMT 500D bars find applications in various construction projects where high-strength reinforcement is required. However, TMT 500D bars are preferred in projects where enhanced ductility, weldability, and seismic performance are critical, such as in high-rise buildings, bridges in seismic zones, and industrial structures subject to dynamic loads. In summary, while both TMT 500 and TMT 500D bars offer high tensile strength, the additional DQT process in TMT 500D bars results in improved ductility and weldability, making them suitable for specific applications where these properties are essential. Builders and engineers should carefully consider the requirements of their construction projects and select the appropriate type of TMT bars based on structural design, environmental conditions, and performance criteria.
