Re - State-of-the-art facility for supply of HARDNED Bar through Induction Quench & Temper Line from the world-renowned manufacturer - Inductotherm Group.

We at P. SOOD & CO. have always believed in adopting the latest technology for the Heat Treatment of steel bars & wires - 

We offer a comprehensive range of services for the heat treatment of steel bars and wires, including soft annealing (spheroidizing), pickling and phosphating of wire rods, cold drawing of bars and coils, peeling and grinding of bars, as well as induction quenching and tempering.

We have commissioned a 1.6 Ton/hour Quench and Temper Line that accommodates bar sizes ranging from 22 mm to 75 mm in diameter and lengths of up to 6 meters. This facility provides single-bar heat treatment, enabling the highest quality and optimal utilization of material potential. It achieves this through the controlled adjustment of the microstructure and steel properties on a bar-by-bar basis. Our state-of-the-art, fully automated production facility is sourced from the renowned Inductotherm Group.

 This results in uniform mechanical properties throughout the entire bar and batch, meeting the stringent requirements of the automotive industry, oil fields, windmill fasteners, and other steel components that are subjected to high stress.

"induction quench and temper steel" include: induction hardened and tempered steel, induction heat treated steel, quench-tempered steel with induction heating, martensitic hardened steel (with induction), or simply "Q&T steel (induction)" as "Q&T" stands for quench and temper; all referring to the process where steel is heated using induction and then rapidly cooled (quenched) followed by a tempering heat treatment to achieve desired mechanical properties. 

Through hardening is a process used to improve the hardness and tensile strength of a metal alloy. This process involves using a rapid quench technique to change the microstructure of the metal while imparting increased strength. In contrast to case hardening, which strengthens only the outer layer of the material, through hardening strengthens the entire cross-section of the alloy.

Through-hardening steel contains typically 1% carbon and alloying elements for hardenability, exhibiting very high strength but low ductility. Used with martensitic or bainitic hardening.

Steel bars are induction, quench & tempered as per CQI-9 guidelines. 

The dimensions of the heating coils for induction heating are adapted to the bar steel diameter, whereby three different dimensions ranging from 20 to 80 millimeters can be selected. 

This adaptation achieves a high level of efficiency, as the non-contact heating of the steel becomes more effective. 

This increases the energy efficiency and precision of the tempering process, which in turn improves the quality of the steel..

We offer peeled and ground bars as well as the option of cutting off the bar ends and cut-to-length facility.

Understanding Heat Treated Bars: Enhancing Steel Performance

When it comes to optimizing the performance of steel, heat treatment plays a crucial role. Different processes can significantly enhance the machinability, toughness, and strength of various grades of steel. Here’s a closer look at the different types of heat treated bars and their unique benefits.

Heat Treated Bars

1. Quenched and Tempered Bars

Quenched and tempered bars are produced according to specific conditions outlined in various steel standards. This precisely controlled hardening process, combined with strict composition limits, allows for accurate control of hardness post-tempering. The resulting structure of tempered martensite provides these steels with a high level of hardness, making them suitable for demanding applications.

2. Surfaced / Induction Hardened Bars

For steels with a carbon content above 0.30%, induction hardening is employed to achieve a hard, wear-resistant surface while maintaining an unaltered core material. The minimized composition scatter ensures uniform hardness throughout the bar, making it ideal for applications requiring durability and strength.

Conclusion

Heat treated bars are essential in various industrial applications, providing enhanced machinability, toughness, and strength tailored to specific needs. Understanding the different types of heat treatment processes allows manufacturers and engineers to select the right material for their projects, ensuring optimal performance and longevity. Whether it’s for intricate machining or high-stress applications, the right heat treated bar can make all the difference.
