This New Generation Steel is the go-to choice for large infra projects and engineers alike. As the only new manufacturer from South India with state of the art rolling technology from MWE Germany & patented QST from Thermex , our premium quality & cost effective steel are at par with the best in the country. The letters TMX are used to highlight the use of internationally patented Thermex Technology.
Kamachi TMTTM Re-bars conform to IS 1786:2008. They are available in Fe500, Fe500D , Fe600 grade under regular earth quake resistant & CRS (Corrosion Resistant) varieties. Kamachi TMTTM Re-bars are available in 8 to 56 mm sizes
Definitely not! only 100% automated technology ensures a perfect steel bar before passing through German QST technology. Without a good steel bar, no technology can assure consistent quality. At Kamachi, we invite any and everybody to visit and study the technology and compare with the best !
THERMEX Quenching & Self-Tempering Technology is offered by H&K Rolling Mill Engineers Pvt. Ltd. under exclusive & perpetual rights from M/s Hennigsdorfer Stahl Engineering Gmbh, Germany.
Thermex Re-bars have a tempered martensite periphery with fine grain of ferrite pearlite at the core.
The search for a process better than CTD led to the development of THERMEX Technology - a Quenching & Self Tempering (QST)process; and the first choice worldwide.Benefits of the Thermex Re-bars primarily on account of are
Kamachi TMTTM TMT Re-bars are hot rolled from concast route blooms and pass through one of the most advance rolling technologies imported from The MWE Magdeburger Walzwerk Engineering GmbH. Unique slit technology ensures that minimum of 3 bars of 8mm size are produced at a time. This is possible, only if the blooms are of the finest quality. The two steps involved in manufacturing of Kamachi TMT Re-bars are :
The following points give Kamachi TMT™ Re-bars an advantage over their competitors:
Kamachi TMT bar is the fastest growing TMT bar brand in Southern India with Multiple National Level Quality Awards, Reputed business houses trust, Reputed MES, Metro rail, Engineers India limited approvals.
While every company produces the same quality TMT bars, only Kamachi TMT Re-bars can assure that every single piece produced maintains the same quality. This is ensured by installing the state of the art; DCS and PLC controlled production facilities. Test certificate is provided with every bar which can be cross checked at any government-accredited lab for quality verifications.
Also, Kamachi TMTTM Re-bars are made in South India’s first and only integrated factory dedicated for TMT Re-bar manufacturing only. Right from processing Virgin iron ore from the mines: creating blooms: hot charging and rolling along with the Thermo Mechanical Treatment, it happens in a single quality controlled atmosphere to ensure that every bar bearing the Kamachi Trade mark, matches its claim of unbeatable quality.
For every 1 ton of Fe 500 re-bars, 1.2 MT Fe 415 has to be used, hence,

Every Kamachi TMTTM Re-bars is embossed with “Kamachi 500” along with the size/section and the ISI logo.
The State of the art German Mill Technology ensures unique features to ensure quality consistency in every bar. For perspective, we can produce more than 5 crore TMT bars a year!

|Carbon (C)||Hardness, strength, weldability and brittleness||Higher carbon contributes to the tensile strength of steel, that is, higher load bearing capacity and vice versa. Lower carbon content less than 0.1 percent will reduce the strength. Higher carbon content of 0.3 percent and above makes the steel bar unweldable and brittle|
|Manganese(Mn)||Strength and yield strength||The manganese content in steel is not specified as per IS: 1786. However higher manganese content in steel increases the tensile strength and also the carbon equivalent property.|
|Sulphur (S)||Present as an impurity in steel which increases its brittleness||Presence of sulphur should be limited as per IS:1786. Presence of higher sulphur makes the bar brittle during twisting, as higher sulphur content brings the hot shot problem during rolling.|
|Phosphorus(P)||Present as an impurity in steel which increases strength and brittleness||Higher phosphorus content contributes to the increase in strength and corrosion resistance properties but brings brittleness due to the formation of low euctoid phosphicles in the grain boundary. Also lowers the impact value at sub zero temperature level (transition temperature).|
|Copper (Cu)||Strength and corrosion resistance properties||Being a pearlite stabiliser, it increases the strength and corrosion resistance property|
|Chromium(Cr)||Weldability and corrosion resistance||Present as an impurity from the scrap and influences carbon equivalent; weldability and increases corrosion resistance property|
