The purpose of S355J2W railway steel sheet quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of S355J2W railway steel sheet. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the S355J2W railway steel sheet, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.
We can process the steel materials according to your drawing. Or if you can not make drawing, please send us S355J2W railway steel sheet specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.
