What is HYSD bar?

HYSD: When expanded, HYSD stands for High Yielding Strength Deformed Steel; and is also their main characteristic. It is a form of HYSD steel, where the steel bars, after undergoing the mandatory heat treatment process, are cold twisted and deformed.

Why HYSD bars are used?

HYSD Bars (High Yield Strength Bars) The yield strength of these bars is high. These types of bars are used for lightweight structures as well as heavy loaded structures. So, the durability of the structure increases. The carbon content in HYSD bars is more so the strength is more but the ductility is less.

What is the difference between mild steel and HYSD bars?

Though mild steel contains very little carbon, it is ductile and weldable but having low strength. Also, mild steel is highly prone to corrosion. High yield strength deformed bars (HYSD) are manufactured under heat treatment followed by either heat rolled or cold twisted for shaping.

Why HYSD bars are preferred over mild steel bars?

HYSD bars are preferred as reinforcement in R.C.C. over plain mild steel bars, due to following reasons : Higher Strength : HYSD bars have yield strength, higher than that of plain mild steel bars. Better Bond : The HYSD bars have better bond with concrete due to corrugations or ribs on the surface of the bars.

Why are hysd bars better than mild steel?

HYSD Stands for ‘ High Yielding Strength Deformed’. It is a high strength construction steel that owes its superior strength ( than mild steel) to the mechanical twisting of cold bar which forms spiral ribs. However cold twisting process results into a product with high residual stress, deformation and surface defects.

What do you call high yield strength deformed bars?

High Yield Strength Deformed Bars. 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 mild steel. These bars are available as two types: Hot rolled high yield strength bars.
