Answer / m.ranjith kumar

It is the tensile strength of steel when it subjected to
elongation.

For Fe415,
The tensile Strength will be 415N/mm2.

For Fe500,
The tensile Strength will be 500N/mm2.

Answer / paresh

its the yield stress...

Answer / babu lal nayak

The abbreviation Fe stands for Ferrous material ie iron from which the reinforcement steel bars are manufactured.
The number 415 indicates that the Yield Strength (tensile strength when it is subjected to elongation) of steel is 415 N/mm2.

The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated in grades of Fe250, Fe415 or Fe500 depending on their Yield Strength. (The numbers 250, 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.)
