HSE Germany pioneered and introduced Thermex\u00ae<\/sup> in 1969. \u00a0Today, this unique Quenching and Self-tempering (QST) process that enables rolling mills to produce low-cost, high strength deformed bars has been installed worldwide, across Asia, Australasia, Europe, Africa and the Americas.<\/p>\n

Thermex\u00ae <\/sup>rebars meet all the mandatories of civil construction – yield strength, toughness, ductility, weldability and excellent bend properties. This has made it the ideal choice among civil engineers for the construction of apartments, high-rise buildings, hospitals, stadiums and auditoriums, as well as for infrastructure projects like dams, ports and bridges, particularly in earthquake-prone areas.<\/p>\n

The Thermex\u00ae Process<\/h2>\n

The proprietary Thermex\u00ae process consists of two major steps:<\/p>\n

1. Quenching<\/strong> –\u00a0A short, but very precise in-line cooling of the rolled bar. This treatment results in a hardened periphery without any major effect on the core.<\/p>\n

2.Tempering<\/strong> \u2013 As the bars are allowed to cool naturally on leaving the quenching pipes, a thermal exchange (THERMEX) occurs between the hot inner core and the quenched martensite surface.<\/p>\n

The resultant bar structure is a distinct tempered martensite at periphery and a fine-grained ferrite-pearlite structure in the central zone.<\/p>\n

Thermex\u00ae in India<\/h2>\n

The main reason why this patented, German technology was introduced in India was because a large part of India falls within seismic zones 3, 4 and 5. In fact, some of India\u2019s largest cities are built on fault lines.<\/p>\n

In addition, the properties of a Thermex\u00ae 500 grade rebar meets international standards and exceeds those defined in the Indian Standard (IS).<\/h6>\n

HSE Germany has granted H&K Rolling Mill Engineers the exclusive right to market and install Thermex \u00ae Systems and grant Thermex \u00ae license rights to rolling mills in the Indian subcontinent. In the 30 years of their association, H&K India have already executed over 370 projects for Thermex \u00ae Systems orders across the length and breadth of the country.<\/p>\n

Today, approximately 60% of steel rebars produced in India are Thermex \u00ae rebars.\u00a0In fact, <\/strong>it has become common practice in the country for government departments, leading construction firms, municipal corporations and reputed builders to specify Thermex\u00ae by name in their tenders.<\/p>\n
