Q415NH steel plate chemical composition

The grade of Q415NH steel consists of the first letters of the Chinese pinyin for "yield strength", "high weather resistance" or "weather resistance", "Q", "NH", the lower limit of yield strength and the quality grade (A, B, C, D, E).

For example: Q415NH

Q - the first letter of the Chinese pinyin for "Qi" in yield strength;

415 - the lower limit of the lower yield strength of steel, in MPa;

NH - the first letters of the Chinese pinyin for "Nai" and "Hou" respectively;

A, B, C, D, E - quality grades.

The design of these chemical compositions and mechanical properties introduced above ensures the excellent performance of Q415NH steel plates in various harsh environments, including high strength, corrosion resistance and good processing performance. Different grades of Q415NH steel plates can be selected according to project requirements in specific applications.

Weathering steel, as we all know, forms a rust protection layer on the surface of the metal matrix by adding a small amount of alloy elements such as Cu, P, Cr, Ni, etc., to improve the atmospheric corrosion resistance of the steel. Q415NH steel is a weldable weathering steel, which is widely used in vehicles, bridges, containers, buildings or other structural parts. Compared with high weathering steel, it has better welding performance.
