How are Steel Graded and Which Grades the Steel are used for Different Purposes.

Have you ever thought that people use only one type of steel for various purposes? If so, then it is time you should know that steels are graded differently on their purposes and functionality. You can consult the Best Steel distributor Company in Ludhiana. Their expertise in this field will help you find the best steel. 

Four types of steel are available to us based on their functionality. These are carbon, alloy, stainless, and tool steel. People who make L6 Tool Steel Punjab know the type of steel needed to make their tools. These types of steel have their own functions in their purpose. 

Carbon Steel

They only contain trace amounts of elements apart from carbon and steel. It is the most popular group of steel, accounting for 90% of steel production.

Carbon steel has three subgroups, which are:

  1. low carbon/mild steels(up to 0.3 % carbon) 
  2. Medium carbon steels(0.3-0.6% carbon) 
  3. High carbon steels(more than 0.6 % carbon)

This group of steel is cheap to manufacture and is strong enough for large-scale construction.

Alloy Steels

This group of steel consists of elements like nickel, copper, chromium, and Aluminum(sometimes). These elements enhance the steel’s strength, ductility, corrosion resistance, and machinability.

Stainless Steel

These steels contain 10-20% of chromium as their alloying element. Nickel, silicon, manganese, and carbon are also present in this group of steels.

This steel can withstand harsh weather conditions and is capable of resisting corrosion. 304 Stainless Steel is the best example of the material used in electrical materials.

Tool Steel

Tool steels are used to make cutting and drilling equipment. They consist of tungsten, molybdenum, cobalt, and vanadium. These components enhance this steel’s heat resistance and overall durability. 

Steel Grading System

Two types of systems are used to categorize steel based on its components and characteristics. Scientists, engineers, architects, and government departments use these systems to ensure the quality and consistency of steel. These systems are:

  1. ASTM System: This system assigns an alphabet to each metal, according to the overall category, along with numbers sequentially assigned to display the general properties of the metal.
  2. SAE System: This system uses a four-digit number for classification. The first two digits denote the steel type and alloy element concentration. The last two depict the carbon concentration of the metal. 

Steel grading has helped many people in their daily lives. Steels are used for different purposes based on their characteristics. Each characteristic plays an important role in the functionality of the steel for its purposes. 

From cutting, constructing a building, storing food, and scientific purposes, steel has been an essential part of our lives for centuries. Without steel, human lives would not have advanced. It has enhanced our living standards. 

Steel grading is helpful to us in identifying the type of steel we need for our purposes. Hence it is crucial to select the steel based on its grading so that it is suitable for your purpose.
