How can we reduce the cost of 16mo3 material equivalent flame cutting

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in 16Mo3 material equivalent etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the 16mo3 material equivalent, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.

The mechanical properties of 16mo3 material equivalent steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel 16mo3 material equivalent to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.

Most common 16mo3 material 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 16mo3 material equivalent steel plates.
