Bridge steel A514 grade P high strength steel plate 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.
Thin steel 5mm to 10mm A514 grade P high strength steel plate stock list 5*2550*9200, 5.5*2500*10000, 5*2670*8500, 7*2260*8600, 6*2510*10400, 5*1860*12000, 8*2000*10000, 7*2000*8000, 8*2350*8600, 10*2500*8500, 8*2540*8200, 9*2500*9500, 10*2510*10600, 8*2400*6000, 10*2550*8500, 10*2800*6300, 10*1600*12000, 10*2000*6500, 10*2650*8300, 10*2800*6150, 10*2000*8600, 10*2150*5500.
The hot rolling method is to heat the A514 grade P high strength steel plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A514 grade P high strength steel plate rolling process is usually called semi-finished product production, also called blank production.
With high-quality A514 grade P high strength steel plate steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our A514 grade P high strength steel plate steel market and improved the control of steel plate production quality.
