CORROSION RESISTANCE STEEL
The controlled thermo mechanical treatment also results in a uniform and thick tempered martensitic rim, completely free from internal stress. This martensitic rim improves the corrosion resistance as well as fatigue strength of the AF Star / MS Life TMT Re-bars when compared to other TMT Re-bars.
AF Star / MS Life CRS TMT Re-bars have been tested in rigorous corrosion media and evaluated for various corrosion resistance properties as per ASTM standards viz. Alternate immersion test, salt spray test, atmosphere exposure test, sulphur Di Oxide test and Potentiodynamic test.
As per the different types of corrosion test AF Star / MS Life CRS TMT Rebars more corrosion resistant than normal TMT Rebars available in the market.
