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 415
IS: 1786
Note:
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.
Mild steel bars are used for stress of reinforced cement concrete beams and concrete. The tor steel are used as lugs and ribs and are to minimize slippage.
Diffrence between tmt bars & round bar
Mild steel bars are used in RCC .
TOR Steel bars are used in steel structures.
it has more tensile stress than the mild steel bars..

TOR Steel: Twisted Ore Reinforced Steel
TOR is a Brand Name originally marketed by TORISTEG STEEL CORPORATION of Luxembourg, Germany.
Let us consider a tor steel of diameter 'd' mm and length 1 m d mm=d*10^-6 m Area of cross section,A=(3.14*d^2*10^-6)/4 Volume of steel bar of length 1 m=((3.14*d^2*10^-6)/4)*1 m Sp.Weight of steel=7850 kg/m3 so,Weight of tor steel=((3.14*d^2*10^-6)/4)*7850 Kg Hence 162 is nothing but a constant used for calculating weight of all type of tor steel and it is found out from; (4*10^6)/(3.14*7850)=162

Specifics of their alloys, they'll have different proportions of carbon, iron, chrome etc. These changes will make the one known as steel a little stronger and harder to machine than the one called mild steel.

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.
