S355ML equivalent inpection report

S355ML equivalent, Alloy steel plate can be used for machining machinery and equipment. The requirement of the equipment to the steel plate is very high, so the alloy steel plate is mostly used to manufacture the mechanical equipment. The alloy steel plate can also be used as raw materials for fastening hardware. Nuts and bolts are used in a complex environment, so there must be certain requirements for strength and high temperature resistance. Otherwise, if fracture occurs, it will lead to accidents and cause a series of irreparable consequences.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

Most common S355ML equivalent steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled S355ML equivalent steel plates.

It is a modern high-tech professional enterprise integrating scientific research, S355ML equivalent production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as S355ML equivalent process technology development, technology transfer and related technical consulting and technical services.
