500 D is the steel bars used widely for building constructions owing to superior strength, reliable properties like corrosion resistance, higher ductility, age resistance and rust resistance. Such steel bars never age and show high-quality rib patterns. They can be used for a variety of applications.
The great strength and ductility of 500 D
It is best to learn that these bars have high ductility and show a great strength. The bars are fabulous combination of strength and excellent ductility. The UTS/YS ratio of such bars or the tensility to yield strength of such bars is 1.16. This is much greater than what is being recommended by IS 1786:2008.
500 D bars never age
500 D bear a lot many mechanical properties and so the bars never age. The strength and elongation properties do not diminish overtime. So, the strength of the bars remains intact.
500 D is resistant to corrosion
The bars bear unique microstructure and this gives rise to rebar to offer outstanding bendability. Bearing a tough exterior and ductile core, the bars have excellent workability and bendability.
Much better rib pattern
The best part of these bars is that they show parallel, uniform and a much precise rib pattern to pave the way for superior bond strength. They may be used with concrete. Such uniformity in pattern tends to promote a much stronger and uniform bonding along with concrete for the entire structure. The rolls may also be machined to attain a greater uniformity.
500 D has seismic property
UTS/YS ratio and percentage elongation are important properties for rebaring. Since both properties are excellent here, the bars can bear the pressure of earthquake. These bars come with far better resistance for cyclical loading condition and so it is highly recommended for those areas that are earthquake prone.
Much superior weldability
As the carbon content of bars is low, it guarantees amazing weldability. It ensures easier and much faster welding without any need for preheating.
500 D bears a high fatigue strength which is at par with set standards.
