What is High-Grade special steel?

Steel is basically a combination of iron and carbon manufactured to meet various specifications and requirements in terms of hardness, toughness, wear resistance, heat resistance, machinability, etc. To achieve these characteristics, steel manufacturers use various elements to be mixed into steel (alloy steel).

High-Grade special steel or "special steel", this term refers to steel made by adding various elements to steel such as chromium, manganese, molybdenum, nickel, tungsten, vanadium, magnesium, phosphorus, silicon, sulfur, etc, so that it has a certain chemical composition according to its application. To perform the addition of these elements required a special process, in order to have special properties and meet special needs.

As we know that steel products that are related to us every day also go through various stages. So, what is the classification of special steel?

This time we will discuss high-grade steel products marketed by Bhinneka Bajanas

1. High quality Carbon Steel

As the name implies, this steel contains mostly carbon and iron. This type of steel is relatively inexpensive and easy to produce. Carbon Steels have three main subgroups divided according to the amount of carbon in the metal they contain:

a. Low Carbon Steel/Mild Steel (up to 0.3% carbon)

b. Medium Carbon Steel (0.3–0.6% carbon)

c. High Carbon Steel (more than 0.6%). carbon)

2. Alloy Steel

In contrast to carbon steels, alloy steels are made by adding additional alloying elements such as nickel, copper, chromium, and/or aluminum. This element increases strength, wear resistance, and corrosion resistance.

3. Tool Steel

Tool steels are specialized to excel in tooling, cutting and drilling, hence high hardness is needed to accommodate these requirements. The advantages of this steel are obtained from the elements of tungsten, molybdenum, cobalt, and vanadium contained in it, thereby increasing heat resistance and overall durability.
