The production process and use of A572 Gr50 steel plate

The production process of A572 Gr50 steel plate: electric furnace steelmaking - LF furnace refining - VD furnace vacuum degassing - rolling - flaw detection - normalizing - tempering - steel plate finishing - performance inspection, the company formulates appropriate internal control components and strictly controls the fluctuation range of chemical components , to ensure the stability of the performance of the steel plate.

Strengthen the batching control and smelting operation, effectively control the content of harmful elements such as Sn, Sb, As, Cu, reduce the content of P and S to improve the purity of the steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of the A572 Gr50 steel.

Controlling the temperature rise is adopted to ensure the heating time and temperature, and measures such as controlled rolling are adopted to ensure the inherent quality of the A572 Gr50 steel plate. Strictly control the rolling and heat treatment process, so that the A572 Gr50 steel plate can obtain a reasonable structure and grain size, and ensure that the steel plate has good comprehensive properties.

A572 Gr50 steel plate use:
A572 Gr50 low-alloy high-strength structural steel plates with a thickness of 8-300mm are widely used in engineering structures, such as building steel structures, construction machinery, mining and mountainous machinery, trucks, bridges, pressure vessels, etc. A572 Gr50 steel is perfect for building and construction machinery components that have high requirements for weldability and toughness.
