First introduce the Q235NHA weathering steel plate grade introduction Q235NHA steel plate Chinese reading: Q two three five weathering A, it is also known as: atmospheric corrosion resistance hot rolling steel, also known as corten steel, corrosion-resistant steel, is between ordinary steel and stainless steel Low alloy steel. It belongs to one of the horizontal steel grades in the world of super steel technology.
Q235NHA steel has only a trace amount of weathering steel compared with stainless steel, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. The total amount of alloying elements is only a few percent, not like stainless steel. Ten percent, so the price is lower.
The application of Q235NHA weathering steel plate, high-performance weathering steel and fire-resistant steel can reduce the maintenance cost of steel structure, and provide new solutions to solve the fire and corrosion problem of exposed unshielded steel structure, such as high-voltage electric tower.
The manufacturing and installation process of fire-resistant weathering steel is basically the same as that of conventional steel, and the design method is the same as that of ordinary steel structure, but more test verification is needed. High-strength weathering steel has been promoted and applied in bridge engineering. It is necessary to study design theory and fire-resistant weathering steel can also be applied to floor-supporting panels.
