SA572 grade 65 carbon steel plate sheet biggest 6 mills South Africa

The difference between alloy steel plate and carbon steel has the following points. First, the hardenability of carbon steel is low, and the maximum diameter of water quenching of carbon steel is only 10 mm to 20 mm; second, the strength of carbon steel is only 235 MPa, while that of alloy steel is more than 360 MPa. Third, carbon steel has poor tempering stability. In order to ensure high strength, low tempering is used for carbon steel during quenching and tempering treatment, so the toughness of the carbon steel is insufficient. Fourth, the corrosion resistance, low heat resistance, and wear resistance of carbon steel cannot be compared with alloy steel, SA572 grade 65 carbon steel plate sheet.

Heat treatment is a very important process to improve the performance of SA572 grade 65 carbon steel plate sheet etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with SA572 grade 65 carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
