Mainly refers to steel with a carbon mass fraction of less than 2.11% and without intentionally added alloying elements. Sometimes referred to as plain carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to an iron carbon alloy with a carbon content Wc of less than 2.11%. Carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus in addition to carbon.
Edit this paragraph II. Classification
(1) Carbon steel can be divided into three types according to its use: carbon structural steel, carbon tool steel, and free cutting structural steel. Carbon structural steel can also be divided into two types: engineering construction steel and machine manufacturing structural steel; (2) According to smelting methods, it can be divided into open hearth steel and converter steel; (3) According to the deoxidation method, it can be divided into boiling steel (F), killed steel (Z), semi killed steel (b), and special killed steel (TZ); (4) According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%), and high carbon steel (WC>0.6%); (5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (with higher phosphorus and sulfur content), high-quality carbon steel (with lower phosphorus and sulfur content), high-grade high-quality steel (with lower phosphorus and sulfur content), and high-grade high-quality steel. Note: Generally, if carbon content in carbon steel is higher, the hardness and strength will be higher, but the plasticity will be lower.

| Mainly refers to the steel with the mass fraction of carbon less than 2.11% and without deliberately added alloying elements. Sometimes called plain carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to an iron-carbon alloy with a carbon content of Wc less than 2.11%. Carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus besides carbon. | ||||||||
| Properties of carbon steel | 1. After heat treatment, the hardness and wear resistance can be improved. 2. Proper hardness and good machinability during annealing. 3. Its raw materials are very common, so it is easy to find, so the production cost is not high. |

| Classification of carbon steel | 1, according to the purpose can be divided into structure, tools, free-cutting structural steel these three categories. 2. According to the way of tempering, it can be divided into three types: open hearth steel, converter steel and electric furnace steel. According to the way of deoxidation, it can be divided into boiling steel, killed steel, semi-killed steel and special killed steel. 4. According to carbon content, it can be divided into low carbon, medium carbon and high carbon. |

| Common carbon steel | 1. Carbon structural steel Brand name: Q235-A F, which means σs≥235MPa. Note: Q is the quality grade of yield strength A (with ABCD grade 4), and F boiling steel is characterized by low price and excellent technological properties (such as weldability and cold formability). Application: General engineering structures and general mechanical parts. For example, Q235 can be used to make bolts, nuts, pins, hooks and less important mechanical parts, as well as rebar, section steel and steel bars in building structures. |
|||||||
| 2. High quality carbon structural steel Brand: Example 45, 65Mn, 08F Brand Note: It directly indicates the carbon content of metal. Application: Non-alloy steel used to manufacture important mechanical parts is generally used after heat treatment. Common steel grades and uses: 08F, low carbon content, good plasticity and low strength, used for stamping parts such as automobile and instrument housings; 20, good plasticity and weldability, used for parts with low strength requirements and carburized parts, such as hoods, welding containers, small shafts, nuts, washers and carburized gears; 40Mn, with good comprehensive mechanical properties after tempering, is used for mechanical parts with large stress, such as gears, connecting rods, machine tool spindles, etc. 60, 65Mn steel has high strength; Used for manufacturing various springs, motorcycle rims and low-speed wheels. |
||||||||
| 3. Carbon tool steel Brand: For example, T12 steel means carbon tool steel with Wc=1.2%. Brand Note: T plus metal carbon content in thousandths Features: It belongs to eutectoid steel and hypereutectoid steel, with high strength and hardness and good wear resistance. It is suitable for manufacturing all kinds of low-speed cutting tools. Commonly used steel grades and uses: T7, T8: Making parts that bear certain impact and require toughness. Such as sledgehammers, punches, chisels, woodworking tools, scissors T9, T10, T11: Tools that require high hardness and wear resistance with less impact are manufactured. Such as taps, small drills, dies, hand saw blades T12 and T13: making tools that are not impacted. Such as files, scrapers, razors and measuring tools. |
||||||||
| 4. Cast steel Brand: for example, ZG200-400, which means cast steel with σs≥200MPa and σb≥400MPa. Performance: the casting performance is worse than that of cast iron, but the mechanical properties are better than that of cast iron; Application: It is mainly used to manufacture important mechanical parts with complex shapes and high mechanical properties, which are difficult to be formed by forging and other methods in technology, such as gearbox housing of automobiles, couplers and couplings of locomotives and vehicles. |
