What are the ceramic binders?

When the ceramic tape and protective paper are removed, a part of the adhesive will always remain on the surface of the stainless steel. If the adhesive is not hard, it can be removed with an organic flux. However, when exposed to light or air, the adhesive hardens and forms a source of crevice corrosion. Then it needs to be cleaned mechanically with fine abrasives. The effects of these pollutants are similar to the effects of oil and grease. It is recommended to use a clean brush and clean water or alkaline cleaning agent for washing. You can also use high-pressure water or steam to rinse. The stainless steel whose structure is mainly ferrite in use. The chromium content is between 11% and 30%, Machinable Ceramic Bushing and it has a body-centered cubic crystal structure. This kind of steel generally does not contain nickel, and sometimes also contains a small amount of Mo, Ti, Nb and other elements. This kind of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance. It is mostly used to make atmospheric resistance. , Water vapor, water and oxidizing acid corroded parts. This type of steel has disadvantages such as poor plasticity, significantly reduced plasticity and corrosion resistance after welding, which limits its application. The application of out-of-furnace refining Machinable Ceramic Bushing technology (AOD or VOD) can greatly reduce interstitial elements such as carbon and nitrogen, so this type of steel is widely used. Regardless of whether stainless steel plates or heat-resistant steel plates, austenitic steel plates have the best overall performance, with sufficient strength, excellent plasticity and low hardness, which is one of the reasons why they are widely used. Austenitic stainless steel is similar to most other metal materials. Its tensile strength, yield strength and hardness increase with the decrease of temperature; ceramic plasticity decreases with the decrease of temperature. Its tensile strength increases evenly within the temperature range of 15~80°C. More importantly, as the temperature decreases, its impact toughness decreases slowly, and there is no brittle transition temperature. Therefore, stainless steel can maintain sufficient plasticity and toughness at low temperatures. The heat resistance of stainless steel refers to the resistance to oxidation or gas medium corrosion at high temperatures, that is, thermal stability.
