HYSD BARS PDF

HYSD BARS PDF

Mild Steel has low carbon content, accordingly, it is more workable & has less yield strength Fy= Mpa, HYSD, stands for high yield strength deformed bars Fy=- . TMT: Thermo Mechanically Treated or TMT bars are high-strength HYSD steel also undergoes heat treatment similar to TMT bars, but the. These are also known as HYSD bars. They have higher percentage of carbon as compared to mild steel. Their strength is higher than that of.

This difference comes from the amount of carbon in the two bars.

TMT bars have less residual stress due to the better yhsd process and have better tensile strength when compared with HYSD bars. Unfortunately, the answer you are trying to submit has already been added. HYSD is used where tensile strength requirements are high.

You are commenting using your Twitter account. In a physically perfect world, HYSD would be the better choice but due to reasons listed below, we can see how TMT bars are a better choice. Due to the amazing flexibility and durability exhibited by TMT bars, they can be used for a wide range of construction works and is basically one of the primary reasons why construction workers rely a lot more on TMT bars as compared to HYSD steel bars.

Please make sure that your answer is written in the same language as the question. Deformed bars have a higher tensile strength than that of MS steel bars and the deformations should be uniformly spaced along the length the bar. When compared with TMT bars, HYSD bars cannot provide flexibility and ductility, thus limiting their use in different types of construction works.

Which drill bit material is required for a slot with 3 inches thick mild steel plate in milling? Next Post Previous Post. Let our CV writing experts help you. Also, due to the superiority in the strength of TMT bars and also because of its higher corrosive resistance, TMT bars are better suited for use in large concrete structures and concrete structures built on the coastlines where high humidity is a major issue.

As TMT bars have a uniform and hardened periphery and a considerably softer core, this kind of bars will have the desired tensile strengths coupled with high elongation and ductility as required in the vars of buildings located in areas with regular seismic activity.

To correct these, HYSD or High yielding strength deformed bars were introduced brs reinforcing heavy structure scale construction.

What is the difference between mild steel and HYSD bars? – Spécialités

This results in harder martensitic outer surface while the inner core cools slowly resulting in ductile inner core. Please make sure that your answer is written in the same language as the question. TMT bars provide a longer life to the structures where they are used.

Compared to mild steel, cast iron has: These are manufactured by a quenching and tempering process which allows the outer surface to cool much faster than inner core and hence making a temperature gradient from bar axis to periphery.

Which of the following material has maximum ductility? Mild steel is made of low carbon and iron, with much more of iron than carbon. Mild steels is best for reinforcing the existing TMT bars, mild steel are weaker, low tensile strength, can easily crack when bent and is generally not used in construction nowadays. Cast iron has good compressive strength but relatively poor tensile strength.
