carbon steel is an iron-carbon alloy containing less than 2.11% carbon and containing a small amount of silicon, manganese, phosphorus, sulfur and other impurity elements. The carbon content of industrial carbon steel is generally 0.05% to 1.35%.
As we know, there are many types of steel, let’s talk about carbon steel today. Can you divide the types of carbon steel? Otai will give you the answer.OTAI Steel specialized in the steel industry for over 20 years. OTAI export tool steel to more than 30 countries includes Europe, North America, South American, Middle East, and Asia. OTAI is stable and reliable tool steel supplier for Fortune 500 companies at home and abroad,
Carbon steel is an iron-carbon alloy containing less than 2.11% carbon and containing a small amount of silicon, manganese, phosphorus, sulfur and other impurity elements. The carbon content of industrial carbon steel is generally 0.05% to 1.35%.
The performance of carbon cable steel is mainly determined by the carbon content. When the carbon content increases, the strength, and hardness of the steel increase, however, the plasticity, toughness and weldability decrease. Compared with other steels, carbon steel has the earliest use, low cost, a wide range of performance, and the largest amount of use. Suitable for water, steam, air, hydrogen, ammonia, nitrogen and petroleum products with a nominal pressure PN≤32.0MPA and a temperature of -30-425 ℃.
Among the various types of steel, carbon structural steel has the highest output, a wide range of uses, and the lowest price. It has appropriate strength, good plasticity, toughness, process performance, and processing performance. , Engineering, grooves, angles, etc.), wire and profiled materials, used to manufacture building engineering structures such as factory buildings, bridges, and ships, generally used directly in the hot rolled state.
Classification of carbon steel
1. According to the mass percentage of carbon:
- Low carbon steel (C: ≤0.25%)
- Medium carbon steel (C: 0.25% ≤C≤0.6%)
- High carbon steel (C:> 0.6%)
2. According to the quality of the steel (mainly the content of impurities sulfur and phosphorus):
Ordinary carbon cable steel (S s0.055%, P≤0.045%)
Advanced quality carbon cable steel (S≤0.040%, P≤0.040%)
High- quality carbon cable steel (S≤0.030%, P≤0.035%)
3 .According to the purpose.
Carbon structural steel:mainly used for bridges, ships, building components, machine parts, etc. Carbon content-generally of less than 0.7%.
Ordinary carbon structural steel is divided into three categories: Class A steel is a steel that guarantees mechanical properties; Class B steel is a steel that guarantees chemical composition; Special steel is Steel that guarantees mechanical properties and chemical composition.
Carbon tool steel: mainly used for cutting tools, molds, measuring tools, etc. This type of steel is generally high carbon steel.
