In this article, Baowu will show you the use of stainless steel balls.
Stainless steel balls are usually steel balls produced by stainless steel forging process. The materials of stainless steel balls commonly used at this stage are 201, 302, 304, 316, 316L, 420, and 440C. The diameter of stainless steel balls generally ranges from 0.5-100mm.
The stainless steel ball has the characteristics of corrosion resistance, but the material of stainless steel is not easy to rust, but not easy to rust. The principle is that by the addition of chromium element, a dense layer of chromium oxide is formed on the surface of the steel, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel, so as to prevent the steel from forming. rust effect.
Stainless steel balls of different materials also have different uses.
440/440C stainless steel balls are mainly used in bearings, stamping/hydraulic parts, valves, seals, refrigeration equipment, aerospace high-precision mechanical parts, handicrafts, and toys.
420 stainless steel balls are mainly used in various types of precision machinery, bearings, electrical equipment, transportation tools, household appliances, etc. It is mostly used to manufacture parts that are resistant to atmospheric, water vapor, water and oxidative acid corrosion.
304 stainless steel ball is the most widely used steel ball on the market. It can be used in medical equipment, chemical industry, aviation, aerospace, plastic hardware: perfume bottles, sprayers, valves, nail polish, motors, switches, electric irons, washing machines, refrigerators, Air conditioners, medicinal materials, auto parts, bearings, instruments, baby bottles.
316 stainless steel ball is a product with high requirements, usually used in special industries such as medical equipment, chemical industry, aviation, aerospace: perfume bottles, sprayers, valves, nail polish, body accessories, mobile phone boards.
201 stainless steel balls are widely used in various hardware industries, handicrafts, plastic products, such as lamps, switches, motorcycle accessories, luggage, bearings, die castings.
302 stainless steel ball is widely used in auto parts, aviation, aerospace, hardware tools, chemical industry. The details are as follows: handicrafts, bearings, pulleys, medical equipment, posts, electrical appliances, etc.
The above is some small knowledge of stainless steel balls and the use of steel balls of different materials. If you want to know more, please feel free to pay attention to Baowu.
