What are the advantages and disadvantages of carbon steel materials?
merit
1. High strength: Carbon steel has high strength and can be used to withstand large loads and forces.
2. Low manufacturing cost: Compared to other alloy steel materials, carbon steel is less expensive to manufacture because its main components are carbon and iron, and it is more widely available and readily available.
3. Good machinability: Carbon steel is easy to process and form, and parts of different shapes and sizes can be manufactured through cold working, hot working, etc.
4. Strong weldability: Carbon steel has good welding performance and is suitable for various welding methods, such as arc welding, gas shielded welding, etc.
5. High corrosion resistance: Carbon steel can improve its corrosion resistance through surface treatment (such as plating, coating) and is suitable for some general corrosive environments.

shortcoming
1. Easy to rust: Carbon steel is prone to rust in a wet, oxygen-present environment, and anti-corrosion measures need to be taken to protect its surface.
2. Low wear resistance: Compared to some alloy steels, carbon steel has low wear resistance and is susceptible to wear and tear.
3. Low High Temperature Resistance: Carbon steel has limited high temperature resistance, and embrittlement and failure may occur when the temperature exceeds its thermal stability.
4. High-carbon steel is easy to carbonize: Under high temperature conditions, high-carbon steel may undergo carbonization, resulting in a decrease in the strength and toughness of the material.
5. Not suitable for extreme environments: Carbon steel may corrode and fail in some extreme environments, such as strong acid, strong alkali, high concentration of salt water, etc.

What is carbon steel?
Steel, as we all know, is a general term for iron-carbon alloys. Carbon steel (referred to as carbon steel) is an iron-carbon alloy with a carbon content of less than 2.11%, and its chemical composition, in addition to iron and carbon, there are also a limited amount of impurities such as silicon, manganese, phosphorus, sulfur, etc., and there will be no other alloying elements.
The output of carbon steel accounts for about 80% of the total steel output, and is widely used in construction, bridges, mention, vehicles, ships, machinery manufacturing, industry, petrochemical, marine development and other fields.

What is alloy steel?
Alloy steel is a steel that adds one or more other alloying elements to the carbon steel in order to increase a specific performance of the steel, such as chromium, nickel, tungsten, titanium, vanadium, manganese, copper, aluminum, molybdenum, etc. These chemical elements are added in different proportions/combinations to give the material different effects, such as increasing hardness, improving corrosion resistance, enhancing strength, improving formability, changing weldability, etc.
The output of alloy steel accounts for about 20% of the total steel output, and is widely used in various fields such as machinery manufacturing, petrochemical industry, construction, daily chemicals, medical equipment, synthetic fibers, and transportation.
