1/8 nm400 steel specifications 4x8 factory near me
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the NM400 steel specifications plate should be derusted before cutting.
The purpose of complete annealing of NM400 steel specifications, wear-resistant plate is to improve the bad structure, such as coarse grain, widmanstatten structure (coarse ferrite with directional growth along with coarse grain) or banded structure caused by high temperature during hot forging, hot rolling, welding or casting of steel plate, so as to refine grain, improve mechanical properties, and reduce stress and hardness.
