Let us get a deep knowledge of carbon steel and alloy steel. After that, we will discuss the difference between carbon steel and alloy steel.
What is carbon steel?
Carbon steels are a class of carbon and iron alloys that contain up to around 1% carbon and 1.65% Mn, with components added in precise amounts for deoxidization and residual amounts of other elements. High carbon steel offers much higher tensile strength.
Carbon steel may also refer to steel that is not stainless steel; in this context, carbon steel may include alloy steel. High carbon steel is used in a variety of applications, including milling machines, cutting tools (such as chisels), and high-strength wires. These applications necessitate a finer microstructure, which increases toughness.
● Application of carbon steel:
It is commonly used structurally in buildings and bridges, as well as axles, gears, shafts, rails, pipelines, couplings, automobiles, refrigerators, and washing machines. Because of its higher tensile strength, high carbon steel is used to make cutting tools, blades, punches, die, springs, and high-strength stainless steel wire.
● Types of carbon steel:
● Low carbon/ Mild Carbon
● Medium Carbon
● High Carbon
What is alloy steel?
Alloy steel is a type of steel that has been alloyed with elements such as molybdenum, manganese, nickel, chromium, vanadium, silicon, and boron. These alloying elements are used to improve the strength, hardness, wear resistance, and toughness of the metal. The proportions of alloying elements can range from 1 to 50%.
The standard term for steels with other alloying elements intentionally added in addition to carbon is “alloy steel.” Historically, alloy steels were expensive luxuries, made based on “secret recipes” and forged into tools such as knives and swords. As improved tool steels and newly available stainless steels, modern alloy steels of the machine age were developed.
● Applications of Alloy steel:
Alloys are widely employed in a variety of industries, including aircraft manufacture, military, industrial, medical, and manufacturing. Aluminum, copper, nickel, stainless steel, and titanium alloys are used in a variety of equipment, machinery, vehicles, structures, and industries.
● Types of alloy steel:
The different types of alloy carbon are:
● Low-alloy steel.
● High-strength low alloy (HSLA) steel.
● High-alloy steel.
● Stainless steel.
● Microalloyed steel.
● Advanced high-strength steel (AHSS)
● Maraging steel.
● Tool steel.
How does carbon steel differ from alloy steel?
There are many differences between carbon steel and alloy steel. Let us read about it
● Composition
Alloy steel = Iron + carbon + Alloying element
Carbon steel = Iron + Carbon
● Resistance to Corrosion
Alloy Steel: Alloy steels are resistant to corrosion.
Carbon Steel: Carbon steels are less corrosion resistant.
● Strength
Alloy Steel: Alloy steel has a lower strength than carbon steel.
Carbon Steel: Carbon steel is extremely strong.
● Weldability
Alloy Steel: Alloy steel has high weldability.
Carbon Steel: Carbon steel has low weldability.
● The Melting Point
Alloy steels have extremely high melting points.
Carbon steels have very low melting points.
● Ductility
Alloy Steel: Alloy steel has high ductility.
Carbon Steel: Carbon steel has low ductility.
Other differences are like:
Carbon steel v/s Alloy steel
1. The carbon content of up to 2.1 percent by weight Any additional elements that do not meet the minimum is considered impurities. Alloy steel also contains carbon, but additional alloying elements are employed to further enhance and personalize the metal’s qualities.
2. The more the carbon content, the harder carbon steel can be heat treated, although alloying components, not just carbon, influence heat treating results. Additional factors can influence both the necessary quench rate and the grain structure. Steel’s toughness and tensile strength can be altered through alloying.
Conclusion:
The composition of elements in steel varies depending on the type of steel. Steels are thus classified mostly based on their composition. Steel comes in two varieties: alloy steel and carbon steel. The primary distinction between alloy steel and carbon steel is that alloy steel contains significant amounts of additional elements other than iron and carbon, whereas carbon steel has only trace amounts of other elements other than iron and carbon.
We covered the distinctions between alloy steel and carbon steel in this post to help you comprehend these commonly used terminologies in the manufacturing and machining industries. Alloy and carbon steel will continue to play a critical and dominant role in the future due to their exceptional mechanical qualities.
