What is the BBN popular 09CuPCrNi-B steel application

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce popular 09CUPCRNI-B steel, hot-rolled seamless steel tube by continuous rolling mill.

popular 09CUPCRNI-B steel, S355J2WP plate is a high phosphorus corrosion resistant structural steel, and P is the chemical element phosphorus. S355J2WP steel enhances the atmospheric corrosion resistance applied at ambient temperature. In order to achieve the corrosion resistance, some specific alloy elements, such as P, Cu, Cr, Ni, Mo, etc., are added to form a protective oxide layer on the metal surface under various climatic conditions.
