About welding of S620QL EN 10025-6 high strength steel

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product S620QL EN 10025-6 high strength steel structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel S620QL EN 10025-6 high strength steel supplier in the world.

Carbon steel SA516Gr70 corresponding material is SA516 Gr485 steel. SA516 Gr485 is called according to the min. tensile strength 485MPa. Our company can supply S620QL EN 10025-6 high strength steel, ASME SA516Gr70 carbon steel plate and sheet with thickness ranging from 5mm to 150mm. SA516Gr70 steel plate for pressure vessels and boiler is delivered in hot rolling, controlled rolling, normalizing, while plate thickness greater than 40mm must be normalizing.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. S620QL EN 10025-6 high strength steel, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

In order to improve the S620QL EN 10025-6 high strength steel corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main S620QL EN 10025-6 high strength steel coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking S620QL EN 10025-6 high strength steel sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
