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:
