Engineering Materials

Since the earliest days of the evolution of mankind, the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials, fashioned in many different ways, to satisfy our requirements for housing, heating, furniture, clothes, transportation, entertainment, medical care, defense and all the other trappings of a modern, civilised society.

Most materials doesn’t exist in its pure shape , it is always exist as a ores During the present century the scope of metallurgical science has expanded enormously, so that the subject can now be studied under the following headings :

  1. a) Physical metallurgy
  2. b) Extraction metallurgy
  3. c) Process metallurgy

In the recent years studying the metallurgy science gave to humanity an ever growing range of useful alloys. Whilst many of these alloys are put to purposes of destruction, we must not forget that others have contributed to the material progress of mankind and to his domestic comfort.

This understanding of the materials resources and nature enable the engineers to select the most appropriate materials and to use them with greatest efficiency in minimum quantities whilst causing minimum pollution in their extraction, refinement and manufacture.

Difference between 304 and 316 stainless steel
Both are non-magnetic, austenitic, and non-hardenable through heat treatment. Each of these stainless steel grades will resists corrosion, are quite durable, and are easily formed and fabricated.

Ferrous metals and alloys
Ferrous metals – plain carbon steels
Ferrous metals are based on the metallic element iron (Latin ferrum =iron).

British standards relating to ferrous metals
It is still widely used but should not be quoted when specifying wrought steels for new designs and products

Ferrous metals- alloying elements
Alloy steels are carbon steels containing less than 1% carbon but to which other metals have been added in sufficient quantities to alter the properties of the steel significantly. The more important alloying elements are as follows –

Some typical steels & their applications
Plain carbon steels, Low-alloy constructional steels, Alloy tool and die steels, Stainless and heat-resisting steels

Flake (grey), cast irons; Grey cast irons; Malleable cast irons
Cast iron is the name given to those ferrous metals containing more than 1.7% carbon.

Spheroidal graphite cast irons & Alloy cast irons

Spheroidal graphite cast iron is also known as nodular cast iron, ductile cast iron, highdutycast iron, etc

Non-ferrous metals and alloy 
Non-ferrous metals and alloys
Non-ferrous metals are all the known metals other than iron
