What are the common uses of SA573 grade 70 carbon steel plate sheet

Over the years, the company has established a standard of SA573 grade 70 carbon steel plate sheet steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to SA573 grade 70 carbon steel plate sheet quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel SA573 grade 70 carbon steel plate sheet can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.

SA573 grade 70 carbon steel plate sheet, Alloy plate is a steel plate with multiple uses because it has the following characteristics. First, better abrasion resistance. Alloy plate is more wear-resistant than ordinary steel plate. It does not scratch or wear, and has applications such as floor steel plate laying, steel plate wall and so on. Second, the alloy plate has higher strength. Third, the alloy plate is more resistant to high and low temperatures. Fourth, the alloy plate has outstanding corrosion resistance. As the steel laid on the ground, it must have good corrosion resistance. Because it will suffer from wind and rain for a long time, it must be very resistant, otherwise it will be damaged once it is corroded.

The microstructure of the quenched and tempered alloy steel, SA573 grade 70 carbon steel plate sheet after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
