though India has a lot of ores.most of the steel plants have old machinery and technology. most Intergrated plants are more than 40 years old maybe in the future we may upgrade them to more powerful and latest ones

50-60 is fastest allowed its usually around 30-40
Schedule 40 and schedule 80 have the same outside diameter (OD). The wall thickness is greater on schedule 80 than it is on schedule 40. So on schedule 80 the inside diameter (ID) gets smaller.
between 30 and 40 degrees preferably 37 like pipe
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.
