SA573 grade 70 carbon steel plate sheet cutting service provider

Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. SA573 grade 70 carbon steel plate sheet, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

The main difference between SA573 grade 70 carbon steel plate sheet, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in SA573 grade 70 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 SA573 grade 70 carbon steel plate sheet steel.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the SA573 grade 70 carbon steel plate sheet steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
