PLANT LOCATION PROBLEMS * During 1970 government of india decided to expand the steel production under public sector units (psu). Three locations were selected to set up the plant. 1. Vijayanagar steel plant in bellary Karnataka. 2. Salam steel plant in TN. 3. Vizag steel plant in AP. * A panel of eminent personalities was formed to analyze the locations. * The important raw materials for steel are : 1. Iron ore : should contain atleast 60% of iron and <30% of ash

microstructure of hot dip galvanised coatings was investigated in the second part. Both Zr and Mn can inhibit the layer growth of active steels with high Si content. Thus‚ Mn and Zr might be an alternative addition to Ni which can control the excessive reaction of the active steels. Addition of 0.8 wt % Cu significantly increases the coating thickness of the galvanised steel containing

or in multiples. Alloys can be classified into two main categories:Interstitial alloy. It is when smaller elements‚ such as boron‚ carbon‚ nitrogen‚ or silicon‚ fill the spaces or interstice of the main metallic structure or solvent. For example‚ steel is an interstitial alloy in which carbon atoms fill the holes between the crystal structures of iron. Substitutional alloyIt is formed when the solute atoms take up positions of solvent atoms in the crystal lattice. If the two metal atoms are about

invention that benefited business organizations was the Bessemer process. The Bessemer process revolutionized steel making by making it possible to produce large quantities of steel at a low cost. Andrew Carnegie saw the way that the Bessemer process would make producing steel easier‚ and‚ using crafty methods‚ took over the steel industry by using this process. His control of the steel energy was one of the first monopolies and was the first business to use the method of horizontal consolidation

It is the most frequently asked questions. Shortly speaking‚ ferrous metals and alloys contain iron while non-ferrous materials do not. Ferrous metals include mild steel‚ carbon steel‚ stainless steel‚ cast iron‚ and wrought iron. These metals are primarily used for their tensile strength and durability‚ especially mild steel which helps hold up the tallest skyscrapers and the longest bridges in the world. Besides‚ most ferrous metals also have magnetic properties‚ which make them very useful
