Ceramic material is an inexpensive material, but customers have very high requirements for its surface quality. Various defects such as scratches, pits, sand holes, dark lines, creases, and pollution will inevitably appear in the production process of stainless steel sheets. Therefore, the surface quality, such as scratches, creases, etc., is a high-grade material. It is not allowed, and defects such as pockmarks and sand holes are never allowed in the production of spoons, spoons, forks, because it is difficult to throw them away during polishing. It is necessary to determine Al2o3 Ceramic the quality level of the table according to the degree and frequency of various defects on the surface to determine the product level. Most of the requirements for use are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted. However, other applications are increasingly seeking structural integrity or impermeability. For example, roofs Al2o3 Ceramic and side walls of industrial buildings. In these applications, the owner`s construction cost may be more important than the aesthetics, and the surface may not be very clean. The effect of using ceramics in a dry indoor environment is quite good. However, if you want to maintain its appearance outdoors in the countryside and cities, you need to wash it frequently. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusty. However, to obtain the aesthetic effect in the outdoor environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes. However, 316 stainless steel is best used in severely corrosive industries or marine atmospheres. There are several design criteria that include 304 and 316 stainless steel.
Because "duplex" stainless steel 2205 has integrated good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this steel is also included in the European standards. Product shape, in fact, stainless steel is manufactured in full-standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of thin plates and strip steel, and medium and heavy plates are also used to produce special products, such as the production of hot-rolled structural steel and extruded structural steel. There are also round, oval, square, rectangular and hexagonal welded pipes or seamless steel pipes and other forms of products, including profiles, bars, wires and castings. In order to meet the aesthetic requirements of architects, many different commercial surface finishes have been developed.
Ceramic 3D printing field
Ceramic itself has good corrosion resistance, and stainless steel can still maintain its excellent physical and mechanical properties at high temperatures. It is also widely used in the field of 3D printing.
