China St37-2 carbon steel plate sheet steel supplier factory

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, St37-2 carbon steel plate sheet.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in St37-2 carbon steel plate sheet steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of St37-2 carbon steel plate sheet steel.

The company currently has a number of extended steel processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment, and can provide customers with diversified products and services. In addition, the company has strong technical force, complete production equipment and advanced production technology. The testing methods are perfect and the St37-2 carbon steel plate sheet product quality is high.
