Steel and it's properties

1. STEEL

2. • Steel is an alloy of iron and carbon with a small
percentage of other metals such as nickel,
chromium, aluminum and cobalt etc. Steel is a
hard ductile and malleable Solid.
• There are many different types of steel
classified on the basis of the type of metal used
and the percentage content of the metal in the
particular type of steel.

3. Properties of steel
 Weldability
 Corrosion resistance
 Tensile strength
 Toughness
 Yield stress
 Machinability

4. Types of steel
 Carbon steels
 Alloy steels
 Stainless steels
 Tool steels

5. Carbon steel
Carbon steel contains trace amount of alloying elements and account for 90% of
total steel Production.Carbon steels can be Categorized Into three groups
depending on their carbon content:
 Low carbon steels/Mild steels Contains upto
0.3% of carbon
 Medium carbon steels contains upto 0.3-0.6%
Carbon
 High carbon steels contains more than 0.6%
Carbon

6. Alloy steels
 Alloy steel contains alloy elements (e.g. manganese, silicon,
nickel, titanium, copper, chromium and aluminum) In varying
in order to manipulate the steel’s properties, such as It’s
hardenability, corrosion resistance,Strength, formability,
weld ability or ductility.
 Applications include pipelines, auto parts,transformers,
power generators and electric motors.

7. Stainless steel
Stainless steel generally contain between 10-20% Chromium as
The main alloying element and are valued for high corrosion
resistance. With over 11% chromium, steel is about 200 times
More resistant to Corrosion than mild steel.

8. Tool steel
Tool steel contains tungten, molybdenum, cobalt and
Vanadium in varying quantities to increase heat resistance and
durability, making them ideal for Cutting and drilling
equipment.
