Reputation depends on quality,  quality comes from Hard!


Silicon Nitride Ceramic:

Silicon Nitride Ceramics, when molybdenum or molybdenum and nitrogen are present in the steel, the effectiveness of chromium is greatly enhanced, although according to the research, the resistance of molybdenum to pitting corrosion and crevice corrosion is about 3 times that of chromium, and the nitrogen is the same as that of chromium. 30 times, but a lot of research, if there is no chromium or low chromium content in austenitic stainless steel, the pitting corrosion and crevice corrosion resistance of molybdenum and nitrogen will be lost or not significant enough.
The effect of chromium on the stress corrosion resistance of austenitic stainless steel varies with the experimental medium conditions and the actual use environment. In the MgCl2 boiling solution, the effect of chromium is generally harmful, but in the water medium containing Cl- and oxygen, Under high temperature and high pressure water and pitting corrosion as the origin of stress corrosion conditions, increasing the chromium content in steel is beneficial to stress corrosion resistance. At the same time, chromium can also prevent the intergranular type in austenitic stainless steel and alloys that are prone to appear due to the increase in nickel content. The tendency of stress corrosion, the effect of chromium on cracking (NaOH) stress corrosion is also beneficial. In addition to having an important influence on the corrosion resistance of austenitic stainless steel, chromium can also significantly improve the oxidation resistance of silicon nitride ceramics. , Anti-sulfurization and anti-melting salt corrosion performance.
