Try to use EN 10025 S420M steel plates high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the EN 10025 S420M steel plates temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong.

ANDRITZ GROUP is the world's leading industrial group, with 29500 employees and more than 280 branches in more than 40 countries. We have cooperated with their Mexico company for many years about S355J2+N steel plates and cutting sectors. The S355J2+N steel plates EN 10025 S420M steel plates need to cut according to the drawing by standard tolerance, UT, MT and dimension request. The final application of the S355J2+N steel plates and cutting sectors are for assembling hydraulic machine.

Since the beginning of this year, the global EN 10025 S420M steel plates steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global EN 10025 S420M steel plates steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
