Product Name: Chrome Steel Balls Model NO.: ANY Colour: Black Classification: Catalyst Other Names: Inert Ball Purity: 20-30% Material: Ceramic Trademark: OEM Transport Package: Caton Wodden Box Pallet or by Costomers Request Specification: Any Origin: Zhejiang HS Code: 69091900 Product Description He advantages of ceramic ball are the following: 1, high hardness. Ordinary Gcr15 bearing steel vickers hardness is 800 hv, and zirconia ceramic ball hardness is 1700 hv. 2, high wear resistance. In my company product processing technology, for example, ordinary steel ball grinding (allowance a mm) need about two to four hours, and silicon nitride balls processing need at least 150-200 hours. 3, corrosion resistance. The stability of the ceramic material is the best, especially silicon nitride balls, almost does not react with any material, widely used in petroleum, chemical, food and so on need contact with strong strong oxidant and reducing agent industry. 4, high temperature resistant. Ceramic ball in the sintering process go through thousands of degrees of high temperature and pressure, the internal molecular structure is very stable, arrangement is very compact, this makes the thermal expansion coefficient is low, the temperature changes in the structure size almost has no effect. Ceramic ball working temperature can reach 1200 degrees Celsius or higher, and the influence of low temperature is very small, so is widely used in aerospace field. 5, light weight. The weight of the ceramic ball only 50% to 60% of ordinary steel ball, promising in the field of bearings and space. 6, self lubrication. Ceramic ball itself has good self-lubrication property, high machining accuracy. Level can reach the G5, G10, ceramic ball abrasion resistance and stable structure, is not easy to deformation, so it can be processed and applied to a lot of special industries. 7, insulation. Ceramic has good insulating effect. Why choice XINZHOU? 1. Quality, loyalty and service is our faith! Deemed continuous improvement as our permanent pursuits. 2.
