TATA TISCON is a premium rebar brand from Tata Steel, the largest steel company in the Indian private sector and sixth largest in the world. It holds laurel of being the first Thermo Mechanically Treated (TMT) rebar in the country. Even since its inception in the year 2000, Tata TISCON has been shaping up the chaotic market of rebar commodity in India with its numerous initiatives. TISCON is new generation high strength ribbed reinforcement bar, the only rebar in India that has acquired the ‘Superbrand’ status. The new grade of 500D is different from ordinary bars in the method of manufacturing and consequently, in its combination of properties. As part of chemistry, any rebar necessarily contains two harmful impurities, Sulphur (S) and Phosphorus (P) in varying levels, which reduce the strength of steel in extreme hot and cold conditions. In Tiscon 500D, the combined level of Sulphur and Phosphorus is restricted to a maximum of 0.075% in 500D.
A cutting-edge product from Tata Tiscon, Plasma Rebar is the only rebar brand in India manufactured using patented EPT - Electrolytic Plasma Technology. Plasma rebars are coated with zinc and treated with an additional surface passivation for higher resistance to corrosion in atmospheric environment and cement-concrete medium. The product has good coating consistency, superior corrosion performance and suitability to Indian construction market.
The salt spray test is a standardized and popular corrosion test method as per ASTM B117-11, used to check corrosion resistance surface coatings. Salt spray testing is an accelerated corrosion test that produces a corrosive attack to coated samples in order to evaluate (mostly comparatively) the suitability of the coating for use as a protective finish. The appearance of corrosion (rust or other oxides) is evaluated after a pre-determined period of time. Test duration depends on the corrosion resistance of the coating; generally, the more corrosion resistant the coating is, the longer the period of testing before the appearance of corrosion/ rust.
