Bridge steel BP300 bulletproof size list 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.
