Surface heat treatment methods for EN 10025 S420ML steel plates

Try to use EN 10025 S420ML 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 S420ML steel plates temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced EN 10025 S420ML steel plates technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel EN 10025 S420ML steel plates production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical EN 10025 S420ML steel plates personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and EN 10025 S420ML steel plates after-sales service of the project.
