Product Introduction
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.

As an important category of high-performance steel, carbon steel plates have shown diversified application scenarios in energy transformation and industrial upgrading. They are widely used in the construction industry, machinery manufacturing, automobile manufacturing, shipbuilding and rail transportation, bridges, etc.Q195, Q215, Q235 steel has low carbon mass fraction, good welding performance, good plasticity and toughness, and certain strength. It is often rolled into thin plate, steel bar, welded steel pipe, etc. Used in bridges, buildings and other structures and in the manufacture of ordinary rivets, screws, nuts and other parts.
The mass fraction of carbon in Q255 and Q275 steel is slightly higher, the strength is higher, the plasticity and toughness are better, and it can be welded. It is usually rolled into section steel, bar steel and steel plate as structural parts and to manufacture connecting rods, gears and couplings of simple machinery. Sections, pins and other parts.
