CRS is a patented technology by HSE Germany, which is used to manufacture thermo processed bars across the world. The CRS TMT sariya uses a specialised Quenching and Self-Tempering process that applies a two-phase cooling process while manufacturing steel bars.
In the CRSTMT manufacturing process, the bar is exposed to high-pressure water sprays in the rolling mill – this cools the surface and hardens it. In the next phase, the hot core is allowed to cool at ambient temperature on cooling beds. The final result is a steel bar that has an outer structure of tempered martensite and a core of fine-grain ferrite-pearlite.
The manufacturing process gives the resulting CRS TMT bar several advantages over the ordinary sariya -`
- Superior strength – CRS TMT bars get their strength from two main factors – their structure, which has a hard outer core and their ribbed patterns. The cross-ribbed pattern gives them better bonding strength with concrete and keeps the entire structure strong.
- Bendability – due to its malleable inner core, the CRS TMT bars have enhanced bendability. This gives them more flexibility during the construction process, as they can be easily bent to align with the construction and design requirements.
- Earthquake resistant – The highly flexible nature of CRS TMT bars also makes them perfect for construction in earthquake-prone areas. They have higher elongation compared to ordinary sariyas, and this allows the structure to withstand high stress during a seismic event. In Moira Sariya the addition of manganese gives its TMT bars even higher ductility, which can bear large deformations during an earthquake.
- Corrosion-resistant – The CRS TMT process gives the steel bars an advanced corrosion-resistantproperty. Moira Steel takes this a step further by adding copper, nickel, and chrome to the raw material, giving its TMT bars higher resistance to rust. Due to this feature, CRS TMT steel is considered absolutely vital for construction in regions that have high moisture or salinity such as coastal areas.
- Better suited to welding – due to their low carbon equivalent, CRS TMT steel bars have far superior weldability compared to ordinary sariya. This allows them to be easily bent into various shapes, making them perfect for innovative construction purposes.
The unique properties of CRS TMT sariyas make them the default steel choice for building long-lasting structures. Along with all the advantages mentioned above, CRS TMT steel bars are also highly cost-efficient – not only do its better load-bearing capacities ensure that less steel is used during the construction, but its corrosion resistance feature also saves money in the long term on reduced maintenance.
