In practical application, the use of S355J2W weathering steel is still the main trend of railway vehicles. High corrosion resistance, high strength and low cost are the main development direction of S355J2W railway vehicle steel.
1. Development of high corrosion resistant S355J2W weathering steel
The railway vehicles are constantly worn by corrosion of the atmosphere and the dynamic load. The harsh application environment put forward strict corrosion resistance requirements to S355J2W weathering steel. It is the actual demand of railway vehicles to develop S355J2W weatherproof steel with better corrosion resistance.
2. Development of high strength S355J2W weathering steel
The effective measure to reduce the weight of vehicles is to use high strength steel, so as to increase the load. Therefore, the development of high-strength S355J2W weathering steel for railway vehicles is also the main task of researchers, and at the same time, we need to solve the problems of welding, low temperature impact and cold bending.
3. Development of low cost S355J2W weathering steel for railway vehicles
The use of low cost steel is one of the effective ways to reduce the cost of railway operation. The way to do this is to further analyze the mechanism of atmospheric corrosion resistance, and develop low cost S355J2W weathering steel with excellent properties through adjustment of alloy composition and process improvement. This is also the research and development trend of S355J2W weathering steel in the future.
