Casting; Alloy Steel Casting

Casting is an ancient manufacturing technique used for obtaining complex shapes. According to the research of the New World Encyclopedia, casting originated in India and the Middle East, in 3000 B.C.E, At first, this procedure was used for manufacturing tools, weapons, jewelry, ancient art pieces, etc. By the time, this procedure spread worldwide and is now used in different industries for obtaining complex shapes. 

Casting is broadly divided into different categories. Some types of casting are listed below:

  • Sand casting
  • Die casting
  • Silica sol casting
  • Water glass casting
  • Alloy steel casting
  • Carbon steel casting
  • Vacuum die casting
  • Squeezing die casting, and more. 

Out of the various types of castings, the casting which is used for enhancing the mechanical properties is known as alloy steel casting.

Alloy steel casting:

In this type of casting, the metals like chromium, manganese, vanadium, silicon, nickel, and boron are alloyed together in the proportion of 1% to 50% by weight. Alloy steel casting is further divided into two groups.

  1. Low alloy steel casting
  2. High alloy steel casting

The only difference between low alloy steel and high alloy steel is that 8% alloying elements are used in low alloy steel casting, and more than 8% alloying elements are required in high alloy steel casting. Also, stainless steel casting and carbon steel casting together make up the alloy steel casting.

Low steel casting is generally more preferred for improving the tensile strength and yield, whereas high alloy steel casting is used for making such materials that are heat, corrosion, and water-resistant.

The parts that are obtained from different types of casting methods are widely used in different industries like railways, automotive and vehicles, agricultural machinery, valves and pumps, and more.
