FE 450 is a steel grade used in the manufacture of pipes or bars. In the word Fe in the term IS 4923 FE 450 Pipes stands for Iron, whereas the numerical figure 450 suggests the minimum yield stress of these pipes in MPa. Hence the minimum yield stress of these pipes is about 450 Mpa. Pipes of this designation are manufactured using standard IS 4923. This standard is used in the manufacture of hollow IS 4923 FE 450 Carbon Steel Pipe. Generally, these hollow pipes are designed to be applied as structural components in the construction industry.
This particular Indian standard has details such as Manufacturer Name or Logo or Trade-mark mandatorily to be embossed on all hollow Carbon Steel Is 4923 Fe 450 Seamless Tubes produced. Each hollow carbon steel tube needs to have size designation marked over it. With regards to coating, the hollow IS 4923 FE 450 mild steel tube could be finished by either varnishing, painting or even by externally oiling the tube. Or, if required, the Is 4923 Fe 450 Black Erw Pipes could be galvanized as synchronised amidst both the purchaser as well as the manufacturer. In case of galvanizing, the volume of element zinc, that is to be used for coating the IS 4923 FE 450 erw steel tubes needs to be as per the correspondence between both the manufacturer and buyer.
