China A572 grade 65 carbon steel plate sheet stock for sale

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate A572 grade 65 carbon steel plate sheet shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, A572 grade 65 carbon steel plate sheet product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel A572 grade 65 carbon steel plate sheet products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the A572 grade 65 carbon steel plate sheet market and has strong competitiveness.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A572 grade 65 carbon steel plate sheet etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
