What does Fe500 steel mean?
May 05, 2013 5:14PM
Fe stands for Ferrous material ie iron from which the reinforcement steel bars are manufactured.
The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated as Fe415 or Fe500 depending on their Yield Strength. (The numbers 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.)
As per IS : 1786 Yield Stress (also known as 0.2% proof stress) of Fe 500 is 500 N/mm2.
So, Fe500 steel means the reinforcement steel rods (or bars) that can safely withstand an Yield Stress of 500 N/mm2.
