Material | Features | Application |
304 stainless steel is a typical representative of austenitic steel. It is generally non-magnetic, but it will be magnetic after passing through the photosphere. It can be demagnetized and its hardness is HRC≤26. Has good rust and corrosion resistance. | 304 stainless steel ball is widely used in the market for a wide range of steel balls, can be used in medical equipment, chemical, aviation, aerospace, plastic hardware: perfume bottles, sprayers, valves, nail polish, motors, switches, electric irons, washing machines, refrigerators , air conditioners, medicines, auto parts, bearings, instruments, bottles. | |
316 stainless steel is austenitic steel with HRC≤26, which is more suitable for industries with higher anti-corrosion requirements. All performances are better than 304 stainless steel balls. Both 304 stainless steel and 316 stainless steel are food grade stainless steel. | 316 stainless steel ball is a relatively high demand product, usually used in special industries such as medical equipment, chemical, aviation, aerospace: perfume bottles, sprayers, valves, nail polish, body accessories, mobile phone boards.
| |
It belongs to the section of nickel-plated steel, austenitic steel, non-magnetic, with low price and excellent performance. It can be processed, welded and drilled with hardness HRC≤28. (Note: The new steel ball reminds you that 201 stainless steel ball can not be used in industries with high anti-rust and anti-corrosion requirements such as seawater or acidic substances). |
| |
420 stainless steel balls are commonly used in industries where high precision and rust resistance are required: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, crafts, valves, and petroleum.
| ||
Metallographic organization belongs to martensitic steel, and the production process is relatively high. There are few enterprises that can produce stainless steel 440C in China, so enterprises that can produce 440C materials are often praised as special stainless steel. The heat treatment process is relatively complicated, easy to crack, and has high precision requirements. It is a relatively hard stainless steel ball in the steel ball: HRC≧58. | 440C stainless steel balls are commonly used in industries where high precision and rust resistance are required: aviation, aerospace, bearings, motors, high precision instruments, valves, and petroleum
|
Application Of Steel Balls
Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber,
military, textile industry. Applications in photographic devices, medical instruments, quick couplings, recirculating balls,
ink cartridges, jewels.
