A brief introduction of Steel Making

      In simple words, steels are deformable alloys of iron with carbon and other elements, generally manganese, silicon, sulphur, and phosphorus.

CLASSIFICATION OF STEELS AND STEEL MAKING PROCESSES:
There is no unique universally adopted classification of steels because they have got extreme variation in their properties, as produced by different methods.  They can be classified by following features:
1. APPLICATION : Furnace and Boiler Steels, Steels for railway Transport, Structural Steels, Ball-Bearing, Tool Steels Spring Steels, Transformer steels, Stainless Steels Gun Steels , Tube Steels , Etc.
2. QUALITY: Depending on the difference in allowed concentration  of harmful impurities, i.e. plain, quality and high quality grades.
3. COMPOSITION: Here they are grouped into, carbon steels, low, medium and high alloyed steels.
4. BY THE NATURE OF STEEL SOLIDIFICATION IN MOULDS: Killed, Semi-    Killed and Rimming Steels.
5. BY THE MANUFACTURING PROCESS:
a. BY THE TYPE OF STEEL MAKING PLANT: Converter Steel, Open Hearth Steel, Electric Steel, Electro Slag Remelted Steel, Etc.
b. BY THE TYPE OF PROCESS:  Basic and Acid Open hearth steel, basic and acid electric steel, vacuum degassed steel, steel treated with synthetic slags, inert gas blown steel, etc.
c. By the state of metal: In solid state (ex: sponge iron), in electrolyte state, in powdered state, in pasty state, in molten or cast state.
