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. The controlled thermo mechanical treatment also results in an 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.
