The eight major types of steel include stainless steel, bearing steel, hot working steel, alloy structural steel, carbon bonded steel, cold working steel, high performance steel, and plastic mold steel

The main reason is that the content of various elements in steel varies, resulting in different properties of steel and more suitable uses in use.

China's steel consumption is mainly concentrated in eight major industries: construction, machinery, automobiles, home appliances, shipbuilding, petrochemical, container, and railway.

Steel (steel), an alloy of iron and carbon, with a carbon concentration below 2%. After heating treatment, there will be significant changes in properties. Steel containing only carbon is called carbon steel, or ordinary steel, which broadly includes alloys containing other elements. Other common steels include:

Adding chromium and nickel to stainless steel results in a rust resistant oxide film on its surface

Synthetic steel

Alloy steel - The addition of other metals such as chromium, nickel, tungsten, vanadium, etc. to steel gives it several new characteristics. Due to the incorporation of various alloying elements, alloy steel can have different characteristics such as rust prevention, corrosion resistance, heat resistance, wear resistance, shock resistance, and fatigue resistance.

Galvanized steel

Hard steel

Mild steel - also known as low-carbon steel, with a carbon content ranging from 0.10% to 0.30%. Mild steel is easy to accept various processing such as forging, welding, and cutting, and is commonly used in the manufacturing of chains, rivets, bolts, shafts, etc.
