A36 s235jr Carbon Steel Plate Sheet
Carbon steel, also called carbon steel, is an iron-carbon alloy with a carbon content ωc less than 2%. Generally, the higher the carbon content in carbon steel, the higher the hardness and the higher the strength, but the lower the plasticity. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus.

Product Description

How many types of carbon steel plates can be divided into?

Carbon steel, also called carbon steel, is an iron-carbon alloy with a carbon content ωc less than 2%. Generally, the higher the carbon content in carbon steel, the higher the hardness and the higher the strength, but the lower the plasticity. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus.

(1) According to the purpose, carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel, and carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel;

(2) According to the smelting method, 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 (ωc≤0.25%), medium carbon steel (ωc=0.25%-0.6%) and high carbon steel (ωc>0.6%);

(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and advanced high-quality steel (lower phosphorus and sulfur content) ) and super high-quality steel. 


Carbon steel classification:

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 steel (mainly the content of impurities sulfur and phosphorus):

Ordinary carbon steel (S≤0.055%, P≤0.045%)

High-quality carbon steel (S≤0.040%, P≤0.040%)

High quality carbon steel (S≤0.030%, P≤0.035%)

3. By use:

Carbon structural steel: mainly used for bridges, ships, building components, machine parts, etc.;

Carbon tool steel: mainly used for tools, molds, measuring tools, etc.; 

Types of steel and their grades:

Ordinary carbon structural steel 

Q195, Q215, Q235
