Letters. The probable reason for using those particular ones is that Fe is the chemical symbol for iron.
The unit weight of Fe 500 grade steel is approximately 7.85 kg/m^3, while the unit weight of Fe 450 grade steel is also approximately 7.85 kg/m^3.
The chemical formula of steel wool is Fe, which represents the element iron. Steel wool is composed mainly of iron, with small amounts of other elements depending on the specific type or grade of steel.
JFE stands for J= Japan Fe= chemical symbol for iron
The principal element in steel is IRON(Fe). A small but varying percentager of carbon alloyed to iron, gives steel.
One example of an alloy with carbon and iron is steel. Steel is a versatile and widely used alloy that contains varying amounts of carbon and iron, which can be adjusted to achieve different properties such as strength, hardness, and ductility.
what is the full form of hscrm
In the context of TMT (Thermo-Mechanically Treated) bars, "Fe" stands for iron, which is the primary component of the bars. The grade designation, such as Fe415, Fe500, or Fe600, indicates the yield strength of the steel in megapascals (MPa). For example, Fe500 means the steel has a yield strength of 500 MPa. Higher grades indicate stronger steel, suitable for various construction applications.
The abbreviationFe 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.

The answer depends on what causes the elongation: a stretching force (tension) or thermal expansion.
The abbreviation 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 in grades of Fe250, Fe415 or Fe500 depending on their Yield Strength.(The numbers 215, 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.)Fe415 indicates that the Yield Strength (tensile strength when it is subjected to elongation) of steel is 415 N/mm2.

They each refer to different grades of steel.The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated into grades 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.Differences between 'Fe415 steel' and 'Fe500 steel':Fe415 has a minimum Yield Strength of 415 N/sq.mm and Fe500 has a minimum Yield Strength as 500 N/sq.mm.The minimum Ultimate Tensile Strength (UTS) of is 485 N/mm2 and that of Fe500 is 545 N/mm2.The minimum Percentage Elongation for Fe415 is 14.5 and that of Fe500 is 12.
The grade of steel is same for both it is 500N/mm2, but FE500D is more ductile than the FE500. This enables the fe500D to withstand the sudden load adsorption capacity, which is encountered during earthquakes, cyclones, Tsunamies etc providing higher safety. This shall be mainly used in the high seismic prone zones. Nothing to do with the concrete and cement mixture. About the cost I don't have much idea.
