Alloy Steel
1) Carbon Steel (IS 2062):
Ø
In this type of steel,
carbon and manganese are the main strengthening elements.
Ø
The minimum
ultimate tensile strength lies in between 410 to 440 MPa.
Ø
The minimum yield
strength lies in between 230 to 300 MPa.
2) High Strength Carbon Steel:
Ø
It has a high
carbon content and shows reduced ductility, toughness and weldability and increased
the strength.
Ø
Structure such as
transmission lines, microwaves towers, tight members are joined by bolting.
Ø
The minimum
ultimate tensile strength lies between 480 to 550 MPa.
Ø
The minimum yield
strength lies between 350 to 400 MPa.
3) Medium and High Strength
Micro Alloyed Steel (IS 8500):
Ø
It has low carbon
content but achieves high strength due to addition of alloys such as Niobium, Vanadium,
Titanium or Boron.
Ø
The minimum
ultimate tensile strength lies between 440 to 590 MPa.
Ø
The minimum yield
strength lies between 300 to 450 MPa.
4) High Strength Quenched and
Tempered Steel:
Ø
In this type of
this steel, heat treated to develop high strength.
Ø
They are tough and
weldable and require special welding technique.
Ø
The minimum
ultimate tensile strength lies between 700 to 950 MPa.
Ø
The minimum yield
strength lies between 350 to 700 MPa.
5) Weathering Steel:
Ø
It is a low alloy
atmospheric corrosion resistant Steel.
Ø
The minimum
ultimate tensile strength 480 MPa.
Ø
The minimum yield
strength 350 MPa.
6) Stainless Steel:
Ø
It is a low Carbon
Steel.
Ø
The chromium (Cr)
content lies in between 10.5% to 20%.
Ø
The minimum Nickel
(Ni) content of about 0.5%.
7) Fire Resistance Steel:
Ø
It is also called
as Thermo Mechanical Treated (TMT) Steel.
Ø
It performs better
than ordinary Steel under fire.
8) Cast Iron:
Ø
It is the impurest
form of Steel and economical.
9) Wrought Iron Steel:
Ø
It is the purest
form of Steel which have high tensile strength and are uneconomical.
10) Mild Steel:
Ø
The Steel used for
engineering purpose is called as mild steel.
11) Alloy Steel:
Ø
It is a high Carbon
Steel used for making equipment’s.
