05CuPCrNi equivalent grades exported to Malaysia

The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, 05CUPCRNI equivalent grades.

Rizhao Steel 5#ESP Headless Strip Production Line Project is a key construction project in Shandong Province. It is also the fifth domestic ESP production line introduced by Rizhao Steel and the sixth ESP production line in the world. Its thinnest design is 0.5mm, which is at the world's leading level. The more than 20 important nodes set by the entire project have been basically completed, and the equipment has entered the commissioning stage. It is expected to be put into operation at the end of November.

The steel such as 05CUPCRNI equivalent grades 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.
