What is the purpose of alloy steel, and what are its different types?

Question

Accepted Answer

Alloy steel is used for its high strength and durability. It is made by adding other elements to iron.

Alloy steel is made by adding other elements to iron to improve its properties.
It is used for its high strength, durability, and resistance to corrosion.
Some common types of alloy steel include stainless steel, tool steel, and high-strength low-alloy steel.
Stainless steel contains chromium and nickel, making it resistant to rust and corrosion.
Tool steel is used for making tools and has high hardness and wear resistance.
High-strength low-alloy steel is used in construction and has improved strength and toughness compared to regular steel.

Accepted Answer

Alloys of steel material plays a significant role in order to maintain the strength, machinability, formability, weldability. There will be certain chemicals which are composed in specific proportion to make alloy steel. Like carbon is used to improve hardness, because wrought iron will be softer, silicon is used for deoxidation, sulphur and phosphorus is used as an impurities to cope up easy material removal while machining process, manganese, nickel and aluminium are used to increase fracture toughness and yield strength and to decrease solidification cracking, copper and chromium is used as corrosion resistant.
