The document outlines the properties and classifications of various engineering materials, particularly focusing on different types of steel and their applications. It discusses material properties such as elasticity, ductility, and hardness, as well as the implications of carbon content in steel. Additionally, it highlights the use and versatility of alloys, carbides, and ceramics in engineering applications.

BASIS :

9. Applications: Used for making bolts and chains, crane hooks, railway
coupling, pipes and pipes fitting plates sheets bars etc.

10. Applications: wire rods, thin sheets, solid drawn tubes, nails, pipes, screws, washers,
boiler plates etc
0.15% to 0.25% carbon content

11. Applications: used for large parts, forging and automotive
components
0.3% to 0.7% carbon

12. Applications: used for springs, high-strength wires, Cutting tools, etc
0.7% to 1.5% carbon

13. Better Surface Finish

14. Done by heating the rod till red hot

15. Alloy steel is steel that is alloyed with a variety
of elements in total amounts between 1.0% and 50% by weight to
improve its mechanical properties.

16. Alloy Steel > Tool Steel

17. Alloy Steel > Tool Steel > High Speed Steel

18. Alloy Steel > Stainless Steel

19. Carbide is a compound composed of carbon and a
less electronegative element
e.g. alkali metals, alkaline earths , Silicon, Aluminum

20. A ceramic is an inorganic, non-metallic solid prepared by the action
of heat and subsequent cooling
e.g. Oxides (alumina, beryllia), Non-oxides (carbide, boride, nitride, silicide),
Combinations of oxides and non-oxides.

21. ■ We discussed various properties of materials.
■ We knew how engineer differ from others.
■ We gained knowledge about various
engineering materials and their types.
■ We discussed about use of materials in real
world.
