Silicon Nitride Ceramic:
Silicon Nitride Ceramics, materials that do not contain titanium and niobium, have a tendency to intergranular corrosion. Adding titanium and niobium, together with stabilization treatment, can reduce intergranular corrosion. A high-alloy steel that can resist corrosion in the air or in chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as plating, and exerts the inherent surface properties of stainless steel. It is used in many applications. A kind of steel, usually called stainless steel. High-alloy steels such as 13 chrome steel and 18-8 chrome-nickel steel represent performance. From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen from the intrusion of the steel and acts as a corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium. For applications where welding is required, the lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may lead to intergranular corrosion of stainless steel in certain environments. The production of silicon nitride is often carried out in dusty sites, and there are often many dusts in the air, which are constantly falling on the surface of the equipment. They can be removed with water or alkaline solution. However, adhesion of dirt requires high-pressure water or steam to clean up. Silicon Nitride Ceramic Ring, materials that do not contain titanium and niobium, have a tendency to intergranular corrosion.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
