What is Carbon Steel?

Carbon steel is a type of steel with carbon content from about 0.05% up to 3.8% by weight, typically between 0.12% and 2%. Most steels with more than 2.5% carbon content are made using powder metallurgy. The high carbon content has a significant influence on the characteristics of steel, especially the strength and hardness, which makes high-carbon steel a great material for making knives, swords, and bladed weapons. Carbon steel in the broad sense refers to steel that is not stainless steel, so it may include alloy steels.  

The statement of carbon steel definition from AISI including:
– No minimum content is required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect;
– The specified minimum for copper does not exceed 0.40% or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65 %; silicon 0.60 %; copper 0.60 %.

Types of Carbon Steel 
According to the carbon content, carbon steel can be divided into the following four types: 
1.Low-carbon steel: 0.05 to 0.25% carbon content. Low carbon steels are more common than high carbon due to the lower production costs, greater ductility, and ease of manufacturing. Low carbon steel easy to machine and weld because of the ductility. 
2.Medium-carbon steel: about 0.3 to 0.5% carbon content. Good wear resistance, used for forgings, automotive parts.  
3.High-carbon steel: about 0.6 to 1.0% carbon content. High strength, good abrasion resistance,  used for springs, edged tools, and high-strength wires.
4.Ultra-high-carbon steel: about 1.25 to 2.0% carbon content. Used for special purposes like knives, axles, and punches.
