engineering custom Si3N4 SiNx ceramic hat machining parts Reputation depends on quality,  quality comes from Hard! Silicon Nitride Ceramic: Silicon nitride is an extremely thin, strong, dense and stable chromium-rich oxide film (protective film) formed on its surface. Prevent oxygen atoms from continuing to infiltrate and continue to oxidize, and gain resistance to rust. Once there is a certain reason, this kind of film is continuously destroyed, the oxygen atoms in the air or liquid will continuously separate out, forming loose iron oxide, and the metal surface will be continuously rusted. Due to cost considerations, many domestic manufacturers have reduced chromium and nickel in stainless steel, and increased the content of manganese. Experts believe that the reason why stainless steel can be rust-free is because of the presence of chromium and nickel. Lowering the content of these two components will reduce the rust-proof performance. Matters needing attention…
