Oman S690QL australian equivalent Hot Rolled Plate Stock

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 australian equivalent 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.

Since its establishment, the company has adhered to the business philosophy of "integrity management, reputation first, mutual benefit", and adheres to the training principles of integrity, innovation and pioneering for its employees. It has long been dedicated to S690QL australian equivalent steel structure, shipbuilding, boiler vessel manufacturing, machinery manufacturing.

Mechanical properties of S420NL-Z35 steel plate: yield strength≥235Mpa, tensile strength 360-510Mpa, elongation≥26%. The properties of S690QL australian equivalent, S420NL-Z35 steel plate determine its application. S420NL-Z35 steel plate has high strength and good welding performance, which is commonly used in the manufacturing of mining machinery, engineering machinery, coal mine hydraulic support and other equipment and structural parts.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between S690QL australian equivalent, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
