Heat treatment of S690QL carbon steel plate sheet

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 S690QL 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.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled S690QL carbon steel plate sheet plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive S690QL carbon steel plate sheet industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

S690QL carbon steel plate sheet, Structural steel is a kind of steel which meets the strength of specific specifications. Structural steel can be divided into: alloy structural steel, carbon structural steel, low alloy structural steel, heat-resistant structural steel and so on. According to different uses, structural steel can be divided into construction steel and mechanical steel. Construction steel is used to build boilers, ships, bridges, workshops and other buildings. Mechanical steel is used for manufacturing machinery or mechanical parts. Mechanical steel is often used after carburizing or quenching and tempering.
