What is the Q460NH steel for railway rolling stock extrusion technology

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural Q460NH steel for railway rolling stock steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

The size, shape, weight and allowable deviation of Q390D, Q390D-Z35 steel plate should comply with the provisions of GB/ T709-2016. The maximum thickness of the steel plate is 135mm. When the Q460NH steel for railway rolling stock, Q390D steel, Q390D-Z35 plate thickness is less than 100 mm, the required performance level in the thickness direction is z25; when the thickness is ≥ 100 mm, the required performance level in the thickness direction is Z35, which shall specifically comply with the provisions of GB/T5313-2010.

Bridge steel Q460NH steel for railway rolling stock is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.

When the stainless steel plate is alloyed with chromium, the type of surface oxide is changed to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the steel surface, so that Q460NH steel for railway rolling stock, stainless steel has a unique surface.
