What Are the Different Types of Steel?
Carbon Steels.
Alloy Steels.
Stainless Steels.
Tool Steels.
What is the most common type of steel?
The 3 Most Commonly used Types of Steel
Tool Steel. As the name suggests, tool steel is often used in the construction of tools. ...
Alloy Steel. Alloy steel is called such because it has small amounts of multiple alloying elements within it. ...
Carbon Steel.
How are the steel classified?
Steel is graded as a way of classification and is often categorized into four groups—Carbon, Alloy, Stainless, and Tool. Carbon Steels only contain trace amounts of elements besides carbon and iron. .Alloy steels contain alloying elements like nickel, copper, chromium, and/or aluminum
What is 350-grade steel?
Grade 350 Mild Steel is a medium strength structural steel plate product with a nominal yield strength of 350 MPa. Typical uses include General Fabrication.
What is the softest metal?
Cesium
Cesium is considered the softest metal, Lead is also considered among the softest metals. Answer 3: Mercury is liquid (molten) at room temperature. Gallium, while solid (if soft) at room temperature, is liquid at body temperature.
What are the examples of alloys?
Alloy. An alloy is a mixture of two or more metals. Some familiar examples of alloys include brass, bronze, pewter, cast and wrought iron, steel, coin metals, and solder (pronounced SOD-der; a substance used to join other metallic surfaces together).
What is the alloying of steel?
Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium, and aluminum. These metals are added to produce specific properties that are not found in regular carbon steel.
What is the 500w TMT bar?
TMT 500W is a reinforcement bar that possesses yield strength of 500 Mega pascals. 'W' means this bar is weldable. TMT means Thermo Mechanically Treated. This is a new generation of high strength steel having superior properties.

Types of steel
1. Classification of Plain carbon steels
1. Low carbon steels (Less than 0.25% carbon)
2. Medium carbon steels (Between 0.25 to 0.60%)
3. High carbon steels (More than 0.60% carbon)
2. Low carbon steels
1. Low carbon steels are relatively soft and weak.
2. They cannot be hardened appreciably by heat
treatment but it can be strengthening by cold
work.
3. They posses good formability and weldability.
Recrystalisation Temperature: The lowest level of heat at which the distorted grain structure of a metal is replaced by a strain-
free grain structure.
3. Application of Low carbon steels
Automobile body parts
Structural Applications (I – Beams, channel and angle iron
8. High carbon steels
1. They are the least ductile (more brittle)
of the carbon steels.
2. They have more wear resistant
3. They are capable of holding a sharp
cutting edge (It is the important property
of making tools)
11. Alloy Steels
Any steel other than carbon steel is called alloy steels.
Alloying elements : chromium, nickel, molybdenum,
vanadium, tungsten, cobalt, boron, copper and others.
12. Classification of Alloy steels
1. Low alloy steels (Having 3 to 4% alloying element)
2. High alloy steels (Having more than 5% alloying element)
13. Low alloy steels
They have similar microstructure
and require similar heat treatments to
that of the plain carbon steels.
14. Classification of Low Alloy steels
1. AISI(American Iron and Steel Institute) steels
2. HSLA(High – strength Low- Alloy) steels
15. AISI(American Iron and Steel Institute) steels
These steels are generally used in machine construction.
It is also referred as constructional steels or structural steels.
They have less than about 5% total addition of elements such as
Cr, Ni, Cu, Mn, Mo, V, etc.
The major interest in this AISI steels group is hardebability
16. HSLA(High – strength Low- Alloy) steels
It is also referred as micro alloyed steels.
They have addition of elements such as Al, Nb(Niobium) and V
either singly or in combination.
17. High alloy steels
They have different microstructure and require heat
treatments than that of the plain carbon steels.
Classification of High Alloy steels
1. Tool and die steels
2. Stainless steels
