Basic knowledge of nm300 steel equivalent grades

nm300 steel equivalent grades, Wear-resistant steel plate not only has excellent mechanical properties, simple cutting and welding property, but also easy maintenance. Therefore, its application is very wide. The application of wear-resistant steel plates in thermal power plants is mainly reflected in the cylinder liner of the coal mill, the burner nozzle, the liner of the coal crusher, the guide vane of the separator, and the ash conduit, etc., The wear-resistant steel plates used in these parts only need to select steel plates with relatively general functions and thickness.

We have a large number of nm300 steel equivalent grades 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 nm300 steel equivalent grades required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, nm300 steel equivalent grades is of high quality? First of all, check whether there are cracks on the surface of the nm300 steel equivalent grades plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as nm300 steel equivalent grades. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
