Product Description

Types of steel bars:

 

(1) Ordinary carbon steel rods: mainly composed of carbon and iron, have high strength and hardness, and are widely used in construction, machinery manufacturing and other fields.

 

(2) Alloy steel rods: By adding other elements such as chromium, nickel, etc. to change its chemical composition and physical properties, it has higher strength and corrosion resistance.

 

(3) Stainless steel rods: Mainly composed of chromium, nickel and other elements, they have good corrosion resistance and are widely used in food processing, medical equipment and other fields.

 

(4) Tool steel bars: After special treatment, they have higher hardness and wear resistance, and are suitable for making industrial tools such as knives and stamping dies.

 

(5) Special steel bars: According to specific uses and requirements, different elements are added, such as high-speed steel, spring steel, etc., to have special physical and chemical properties.

 

Delivery condition:

For hot forged bar, usually the delivery condition is hot forged, annealed rough turned/Black surface.

For hot rolled bar, usually the delivery condition is hot rolled, annealed, Black surface.

For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface

For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
