Main causes of subsurface bubble formation in nm500 wear resistance property

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel NM500 wear resistance property produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

NM500 wear resistance property, Wear-resistant steel plate has good corrosion resistance:The alloy layer of the wear-resistant composite steel plate contains a high percentage of metallic chromium, so it has certain anti-rust and corrosion resistance. It can be used to prevent coal sticking when it is used in coal dropping drums and hoppers.
