Tata Tiscon 550D (marketed under the enhanced 550SD - Super Ductile specification) is a high-strength, micro-alloyed reinforcement steel rebar. The 8mm diameter variant is specifically optimized for seismic performance, structural elasticity, and heavy load-bearing distribution.Mechanical SpecificationsYield Strength (YS): Minimum 550 MPa (Typically achieves an actual performance of 570 MPa).Ultimate Tensile Strength (UTS): Minimum 600 MPa (Maintains a highly resilient ultimate threshold).UTS / YS Ratio: Minimum 1.15. This high gap allows the steel to absorb intense seismic energy and stretch under extreme load conditions without brittle failure.Total Elongation: Minimum 16%. This provides exceptional flexibility, which is vital for building in earthquake-prone zones.
