Silicon Nitride Ceramics:

Silicon Nitride Ceramic Bar is the most important alloying element in austenitic stainless steel. The rust resistance and corrosion resistance of austenitic stainless steel are mainly due to the fact that chromium promotes the passivation of steel and keeps the steel Stable passive results. ○1 The influence of chromium on the structure: in austenitic stainless steel, chromium is an element that strongly forms and stabilizes ferrite, reducing the austenite zone. As the content of steel increases, ferrite may appear in austenitic stainless steel ( δ) Organization. Research shows that in chromium-nickel austenitic stainless steel, when the carbon content is 0.1% and the chromium content is 18%, in order to obtain a stable single austenitic structure, the minimum nickel content is required, about 8% In this regard, the commonly used 18Cr-8Ni type chromium-nickel austenitic stainless steel is the most suitable one containing chromium and nickel. In austenitic stainless steels, as the chromium content increases, the tendency to form some intermetallic phases (such as δ phase) increases. When the steel contains molybdenum, the chromium content will increase and χ will be formed equal, as before As mentioned, the precipitation of σ and χ phases not only significantly reduces the plasticity and toughness of steel, but also reduces the corrosion resistance of steel under some conditions. The increase of chromium content in austenitic stainless steel can make the martensite conversion temperature (Ms ) Decrease, thereby improving the stability of the austenite matrix. Therefore, high chromium (for example, more than 20%) austenitic stainless steel is difficult to obtain martensitic structure even after cold working and low temperature treatment.
