In hot rolling mills the steel bar is passed through a high pressure water quenching system whereby only the peripheral temperature is drastically reduced while the core remains largely unaffected. On leaving the specially designed quenching system, the core heat tempers the peripheral martensite that was formed during quenching. This results in a rebar with a soft core and a uniform hardened tempered martensite periphery - a rebar with high yield strength but with extremely good ductility. Such rebars are ideal for use in high hazard seismic areas.
These bars are produced in bar rolling mills by use of the globally proven and accepted THERMEX Quenching System and Technology of M/s HSE Germany.
In the Indian Region comprising India, Nepal, Bhutan, Bangladesh, Myanmar, Pakistan and Sri Lanka, M/s H&K Rolling Mill Engineers Pvt. Ltd., Mumbai (H&K India) have been given perpetual exclusive rights by HSE Germany to Licence, sell, market, install and commission the unique THERMEX Quenching Systems. As on 1 April 2013, H&K India has received orders for nearly 200 Thermex Systems to be set up in rolling mills - of which about 29 were under excecution. The installed capacity of Thermex QST rebars in India alone is over 14 million tonnes (65% market share). Each Thermex Licensee in Indian Region is subject to strict quarterly audit. Qualified QST engineers visit each Licensee to ensure that the rebar properties are as per the strict standards laid down by HSE Germany and H&K India besides meeting the Standrards of the country.
The Thermex 500 QST rebar meets most global standards and codes and is widely accepted by leading users of rebars because of the uniform properties obtained from the various Thermex Licensees.
In India, the registered trade mark/name THERMEX is owned by H&K India as per permission given by HSE Germany.
Unfortunately, in India, these QST rebars are incorrectly referred to as 'TMT' bars. 'TMT' is an acronym for Thermo-Mechanically Treatment even though no mechanical treatment is involved in the process. This has lead to a number of improper 'TMT' rebars being sold in India with non-uniform tempered martensite periphery at the rebar cross-section - encouraged by this non-uniformity "not being a ground for rejection" as per latest rebar code IS:1786-2008!

What is "QST" steel bars?
Quenching and Self-Tempering (QST) Process Quenching:Immediately after the hot rolling process, the steel bars are rapidly cooled using water sprays. This rapid cooling, or quenching, hardens the outer layer of the bar, forming a martensitic rim while the core remains hot and austenitic. **Characteristics of QST Steel Bars:-** High Strength: These steel bars have high yield strength and tensile strength, making them ideal for use in high-stress applications. Ductility: Despite their high strength, bars maintain good ductility, allowing them to absorb energy and withstand seismic forces. Corrosion Resistance: The quenching process enhances the corrosion resistance , increasing their durability in harsh environments. Weldability: They have good weldability, which is essential for various construction practices. Source:-Steeloncall.
What is TMX steel bars?
TMX steel is a high quality QST bar. Thermex technology is used for this. Thermex bars, unlike CTD bars, have a proven record resisting loss of strength at high temperatures as experienced during fires. Quenched & Self Tempered (QST) steel, can be described as a new-generation-high-strength steel having superior properties such as weldability, strength, ductility and tensile strength, which meets the highest international quality standards. Both Thermex and TMX are trademarks owned by H&K Rolling Mill Engineers Pvt. Ltd. in India.
What is QST rebar?
QST rebars:The acronym 'QST' stands for 'Quenched & Self Tempered' reinforcement steel bars.

What does a rabbi read?
When a rabbi is reading for recreation, he may read Time, Field and Stream, The Wall Street Journal, Scientific American, QST, "Moby Dick", Der Spiegel etc. When he is reading to develop and enhance the scope and timeliness of his professional knowledge, a rabbi may read the Torah, other parts of Tanakh, the Talmud, or any of the thousands of published ancient or contemporary works of analysis or commentary on them.

Today was pay-day at the shop. It could not have come at a better time, as I was flat broke. I was paid my usual $243 after deductions. On my way home, I stopped at the big Green Wall pharmacy and monomart for supplies. Two prescriptions were ready, and as long as I was there anyway, I picked up toothpaste, a notepad, a 30-foot extension cord, and this month's issues of QST, Scientific American, and Patriot Gunslinger. I paid cash at the checkout because Aruna was working the register and I love watching her try to make change. The total with tax came to $44. How much money did I have in my pocket when I got home ?
