What is "QST" steel bars?
QST, or Quenched and Self-Tempered steel bars, represent a significant advancement in construction materials. These bars are engineered through a unique process that involves rapid quenching (cooling) followed by self-tempering. This method results in a steel bar with a hard outer surface and a softer, more ductile core, offering a combination of strength and flexibility that is highly desirable in construction.
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.

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.
