The steel such as hot rolled 09CuPTiRE-B delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
Meaning of S355J2W: S is structural steel, 355 means the yield strength of 355MPa, J2 requires -20℃ impact, and the letter W indicates that the S355J2W steel has the ability to resist atmospheric corrosion. hot rolled 09CuPTiRE-B, S355J2W is a fine-grained steel, which is widely used for welding, bolting and riveting parts of high-speed rail bogies.
