S355J2 steel plate 09CUPCRNI-B steel supplier rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the 09CUPCRNI-B steel supplier single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the 09CUPCRNI-B steel supplier, stainless steel from corrosion.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the 09CUPCRNI-B steel supplier principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
