440C stainless steel ball
Stainless steel ball 440/440C: performance: hardness of 56-58 degrees, magnetic, good corrosion resistance, wear resistance and toughness
Uses: mainly used in bearings, stamping/hydraulic parts, valves, seals refrigeration equipment, aerospace high-precision mechanical parts, handicrafts, toys.
Specification: 0.5mm-Φ100mm
Application areas: 440C stainless steel ball is usually used in industries that require high precision and anti-rust performance: aviation, aerospace, bearings, motors, high-precision instruments, valves, and petroleum.
Characteristics: Metallographic organization belongs to martensitic steel, production process requirements are higher, domestic enterprises can produce stainless steel 440C is relatively small, so enterprises that can produce 440C materials are often dubbed the reputation of special stainless steel. The heat treatment process is more complex, easy to crack, and high precision requirements, is the hardest steel ball in a stainless steel ball: HRC ≧ 58. The hardness is close to the bearing steel ball, but it has stronger anti-rust and anti-corrosion performance than the former.
Comparison: Compared with 440 stainless steel balls, they have stronger anti-rust and anti-corrosion properties, enhanced hardness and improved wear resistance.
420 stainless steel ball
Performance: hardness of 51-52 degrees, magnetic, have a certain corrosion resistance and toughness
Uses: Suitable for all kinds of precision machinery, bearings, electrical equipment, transportation, household appliances, etc. More used in the manufacture of atmospheric, water vapor, water and oxidizing acid corrosion parts.
Specification: Φ2.0-Φ25.4
Application areas: 420 stainless steel balls are usually used in industries that require high precision and anti-rust performance: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, handicrafts, valves, and petroleum.
Characteristics: the representative of martensitic steel, commonly known as stainless iron, magnetic, has good antirust performance, high hardness and HRC50-55.
3. stainless steel ball 304/304HC
Performance: hardness ≦ 28 degrees, non-magnetic after degaussing, anti-rust ability is very strong, salt water immersion for a long time is not easy to rust
Uses: Mainly used in medical equipment, bottles, valves, electronic components, etc.
Specification: Φ1.0-Φ50.8
304 stainless steel ball
Application areas: 304 stainless steel ball is the most widely used steel ball on the market, which 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.
Characteristics: a typical representative of austenitic steel, generally non-magnetic, but after the ball will be magnetic, can be demagnetized, HRC ≤ 26. It has good anti-rust and anti-corrosion performance.
Comparison: 304HC stainless steel ball is softer and easier to process than 304 stainless steel ball, while 304L stainless steel ball has stronger anti-rust and anti-corrosion performance than both of the above, easy to weld, excellent polishing, and more suitable for industries with higher surface requirements.
4. stainless steel ball 316/316L
Performance: Hardness ≦ 28 degrees, non-magnetic after degaussing, strong anti-rust ability, non-corrosive
Uses: Mainly used in medical equipment, food machinery, cosmetics accessories, body accessories, instrumentation, etc
Specification: Φ1.0-Φ38.1
316 stainless steel ball
Application areas: 316 stainless steel ball is a relatively high demand products, usually used in special industries such as medical equipment, chemical, aviation, aerospace: perfume bottles, sprayers, valves, nail polish, body accessories, mobile phone panels.
Features: Austenitic steel, is by far the most high-grade steel ball industry, HRC ≤ 26, the most suitable for anti-corrosion requirements of the industry, the performance is better than 304 stainless steel ball comparison: 316L stainless steel ball is softer and more white, so usually used for human body jewelry. 5. stainless steel ball 201/stainless steel polishing ball
Performance: hardness ≤ 26 degrees, non-magnetic after degaussing
stainless steel ball 201/stainless steel polishing ball
Uses: mainly used in general hardware accessories, household appliances accessories, stamping stainless steel and so on
Specification: Φ1.0-Φ38.1
201 stainless steel ball
Application areas: 201 stainless steel balls are widely used in various hardware industries, handicrafts, plastic products, such as lamps, switches, motorcycle accessories, luggage, bearings, and die-casting parts.
Features: belongs to the nickel-saving steel, austenitic steel, non-magnetic, with low price, excellent performance. Processing, welding, drilling, hardness HRC ≤ 28. (Note: the new new steel ball to remind you, 201 stainless steel ball can not be used for rust, anti-corrosion requirements of the industry such as: sea water or acidic substances).
302 stainless steel ball
Application: 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 instruments, posts, electrical appliances, etc.
Features: 302 stainless steel ball belongs to austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC ≤ 28. Has good rust and corrosion resistance.
