Welding technology of S550Q steel

The ASTM A213 T9 alloy tubing heat exchange finned tube is the most used heat exchanger tube in the heat exchange of gas and liquid. It is to add fin to the common base tube to enhance heating, so as to achieve the fast heat transfer of heat exchanger through heat exchange finned tube. According to the type of materials S550Q steel , it is divided into single-metal finned tube and bimetal finned tube.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials S550Q steel used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to S550Q steel full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our S550Q steel steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.

The automobile steel coil and sheets are one of our main steel materials exported to the overseas. For any questions about automobile steel, for example, JIS G3113 SAPH440 S550Q steel chemical & mechanical composition, S355MC material specification, S700MC material properties, QSTE 380 TM equivalent, please contact us freely. Our sales person and technician will give you professional answers. And welcome to consult us about automobile steel price.
