What is Steel ?
Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to iron. What is mixture of steel
What is Chemical structure of steel
What are the use of steel in mechanical engineering
Stainless steel is typically used in applications where the risk of corrosion is a major concern and not permissible. Areas of use for stainless steel include:
Food processing equipment
Pharmaceutical manufacturing equipment
Aerospace engine components
Kitchen appliances
Certain types of fasteners Uses of Steels
Some vital utilization of steels are given below:
Steel is environment-friendly & sustainable. It posses great durability.
Compared to other materials, steel requires a low amount of energy to produce lightweight steel construction.
Steel is the world’s most recycled material which can be recycled very easily. Its unique magnetic properties make it an easy material to recover from stream to be recycled.
Steel can be designed into various forms. It gives better shape and edge than iron which is used to make weapons.
Engineering steels are used for general engineering and manufacturing sectors.
Steel is highly used in the automobile industry. Different types of steels are used in a car body, doors, engine, suspension, and interior. The average 50% of a car is made of steel.
Steel reduces CO2 emissions.
All types of energy sectors demand steel for infrastructure and resource extraction.
Stainless steels are used to produce offshore platforms and pipelines.
Steels are used for packaging and protecting goods from water, air and light exposure.
Most of the household appliances like fridge, TV, oven, sinks, etc are made of steel.
Steels are used for producing industrial goodies like farm vehicles and machines.
Stainless steel is used as a cutlery material.
Because of its easily welding capability and attractive finishing, steel has become a prominent feature in modern architecture.
Stainless steel gives a hygienic environment. That’s why it is used for surgical implants.
Steel has a wider range of temperature which is used to make large sheets.
Renewable energy resources like solar, hydro and wind power use the stainless steel components.
Mild steel is used for building construction. It is also a highly favored building frame material

Why steel used ?
Steel is the most important engineering and construction material in the world. It is used in every aspect of our lives; In cars and construction products, refrigerators and washing machines, cargo ships and surgical scalpels. It can be repeated over and over again without damaging the property.
How is steel made today?
Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace.
How do you describe a steel?
A generally hard, strong, durable, malleable alloy of iron and carbon, usually containing between 0.2 and 1.5 percent carbon, often with other constituents such as manganese, chromium, nickel, molybdenum, copper, tungsten, cobalt, or silicon.
What is the most common type of steel?
Low carbon steel.
Low carbon steel or mild carbon steel or plain carbon steel refers to carbon steels that have up to 0.30% carbon content.
How can you tell the grade of steel? How do you create steel?
What are properties of steel?
Steel has a number of properties, including: hardness, toughness, tensile strength, yield strength, elongation, fatigue strength, corrosion, plasticity, malleability and creep.
What is Steel ? definition of steel?
1. Based on carbon content:
Low carbon steels
Medium carbon steels
High carbon steels
Low carbon steels:
Composition: 0% to 0.25%.
Microstructure: mainly α - ferrite and a small amount of pearls.
Properties: Excellent flexibility and rigidity. Good machinery and weldability, high formality, rigidity, high durability etc.
For example, mild steel.
Advantages: Lowest cost to produce.
Disadvantages: Martensite is difficult to produce due to its extremely low carbon content.
Applications: Automobile body components, structural shapes, pipes, sheets etc.
Medium carbon steels:
Composition: 0.25% to 0.55% C.
Microstructure: α - Ferrite and pearlite.
Properties: Stronger than less - carbon steel but less hard than that.
Advantages: Best range for adding alloying elements.
Applications: Railway wheels and tracks, gears etc.
High carbon steels:
Composition: 0.55% to 2.1% c
Microstructure: Fe3C, Pearlite (C> 0.8%), - Ferrite and Pearlite (C <0.8%).
Properties: Hardness, strong and minimal flexibility compared to low carbon steels.
Advantages: Making tool steels.
Applications: Knife, hack saw blade, chisel, hammer, drill, die, machine tool cutter, punch etc.
2. Based on the method of making steels:
Based on the method of manufacture of steels, they are classified as Bessemer steel method and electric arc furnace method, the explanation of which is given below.
Basemer steel method:
The principle of the Bessemer converter is to remove impurities from the iron by oxidation and to blow air through the molten iron.
The furnace is made of steel with fire bricks to resist heat.
Impure manganese (MN) and silicon (C) are converted into their respective oxides and they can be extracted.
Electric arc furnace method:
This is a very hot confined region, where heat is generated using electrodes to melt certain substances like steel (scrap) without changing the electrochemical properties of the (metal).
The electric arc generated between the electrode and the metal is used to melt the metal (scrap).

3. Based on the properties of some other types of steels:
Shock-resistant steels
High strength steels
Instrument steels
Spring steels
Heat resistant steels
Shock-resistant steels:
These steels can withstand fatigue loads and shock loads.
High strength steels:
Applied where low weight and high strength are required.
Tool steels:
They are mainly used in their hot or cold conditions for cutting, forming and forging tools and dies.
Spring steels:
Used to make coils and leaf springs.
Heat resistant steels:
These steels can resist corrosion, oxidation and creep at high working temperatures.
4. Based on the effect of alloying components on steel:
Cobalt / Molybdenum:
It has high service temperature or high temperature stability.
Chromium:
It improves rust resistance and abrasion resistance.
Vanadium:
It represents high temperature, hardness and strength.
Aluminum:
It improves fracture toughness and acts as a deoxidant.
Phosphorus:
It increases strength, stiffness and improves machinery.
Sulfur:
It improves machinability.
Silicone:
It shows high hardness.
Magnesium:
It is rough and improves efficiency.
Manganese:
Insert resistance and hardness is high.
Applications of steel:
Due to the high tensile strength of steel, they were used here:
Construction of buildings
Infrastructure
Tools
Ships
Vehicle
Machinery and equipment
Weapons
Machine steel
Spring steel
Boiler steel
Structural steel
Tool steel etc.
