A514 grade Q structural steel,The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.
The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition A514 grade Q structural steel is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).
DIN 17102 TStE355 is mainly used for grain structure steel and normal rolling steel. Tste355 steel plate is a kind of grain structure steel. It is a standard rolled steel plate / sheet specially manufactured for different types of welding structures. It is made of basic materials, with high temperature resistance and low temperature resistance. Product A514 grade Q structural steel is suitable for pressure boiler, mobile and vertical storage tank, high pressure pipeline, bridge, mast, cable, etc.A514 grade Q structural steel
We have a large number of steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.A514 grade Q structural steel
