What Is Wrought Iron
Wrought iron is the purest iron with very low carbon content with respect to cast iron. It contains 99.5% iron but may contain upto 99.9% iron. The carbon content is about 0.02%. It is soft,…
Plastics | Engineering Materials
The plastics are synthetic materials which are moulded into shape under pressure with or without the application of heat. These can also be cast, rolled, extruded, laminated and machined. Following…
What is Metallography
What is Metallography? The study of internal structure of a metal or alloy, in relation to its physical and mechanical properties, under a microscope is called metallography. When the structure…
What is free cutting steel

Stainless Steel | Engineering Materials
Stainless Steel is defined as that steel which when correctly heat treated and finished, resists oxidation and corrosive attack from most-corrosive media. The different types of stainless steels are as…
Allotropic Forms of Pure Iron
Allotropic Forms of Pure Iron - we know that pure substances may exist in more than one crystalline form. Each such crystalline form is stable over more or less well…
Metals for Nuclear Energy

High Temperature Alloys
What are high temperature alloys? The high temperature alloys are those alloys which can withstand temperature in excess of 1100 degree celcius. These alloys are used in components of nuclear plants,…
Cast iron and its types
The cast iron is obtained by remelting pig iron with coke and lime stone in a furnace known as cupola. It is primarily an alloy of iron and carbon. The carbon contents…
