Basic Information

Definition of stainless steel: steel that contains more than 12.5% ​​chromium and has high resistance to corrosion by chemical substances (acid, alkali, salt).

Principle: Stainless steel does not rust, but is not easy to rust. The principle is that by the addition of chromium elements, a dense chromium oxide layer is formed on the surface of the steel, which can effectively block the re-contact of the steel and the air, so that the oxygen in the air cannot enter the steel, thereby preventing the production of the steel. The effect of rust.

 

Classification

 

440C stainless steel ball

Performance: Hardness reaches 56-58 degrees, magnetic, good corrosion resistance, strong wear resistance and toughness

Uses: Mainly used in bearings, stamping/hydraulic parts, valves, seals, refrigeration equipment, aerospace high-precision mechanical parts, handicrafts, toys.

Application areas: 440C stainless steel balls are usually used in industries that require high precision and anti-rust performance: aviation, aerospace, bearings, motors, high-precision instruments, valves, and petroleum.

Characteristics: The metallographic structure belongs to martensitic steel, and the production process requirements are high. There are relatively few domestic companies that can produce stainless steel 440C, so companies that can produce 440C materials are often named as special stainless steel. The heat treatment process is more complicated, easy to crack, and requires high precision. It is the hardest stainless steel ball among steel balls: 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 ball, it has stronger anti-rust and anti-corrosion performance, the hardness is increased, and the wear resistance is also improved.

Folding 420 stainless steel ball

Performance: Hardness reaches 51-52 degrees, is magnetic, has certain corrosion resistance and toughness

Uses: Suitable for all kinds 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 oxidizing acid corrosion.

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, is magnetic, has good rust resistance, and has a high hardness of HRC50-55.

304 stainless steel ball

Performance: Hardness ≦ 28 degrees, non-magnetic after demagnetization, very strong rust resistance, not easy to rust after being soaked in salt water for a long time

Uses: Mainly used in medical equipment, baby bottles, valves, electronic components, etc.

Application area: 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.

Characteristics: A typical representative of austenitic steel, generally non-magnetic, but after passing through the photosphere, it will become magnetized and can be demagnetized, HRC≤26. Has good anti-rust and anti-corrosion properties.

Comparison: 304HC stainless steel balls are softer and easier to process than 304 stainless steel balls, while 304L stainless steel balls have stronger rust and corrosion resistance than the above two, easy to weld, excellent polishing, and more suitable for industries with higher surface requirements.

Folding 316 stainless steel ball

Performance: Hardness ≦ 28 degrees, non-magnetic after demagnetization, strong rust resistance, non-corrosive

Uses: Mainly used in medical equipment, food machinery, cosmetic accessories, human body accessories, instrumentation, etc.

Application areas: 316 stainless steel ball is a relatively demanding product, usually used in special industries such as medical equipment, chemical industry, aviation, aerospace: perfume bottles, sprayers, valves, nail polish, human accessories, mobile phone panels.

Features: Austenitic steel is by far the most high-end steel ball industry, HRC≤26, most suitable for industries with high anti-corrosion requirements, all properties are better than 304 stainless steel balls Comparison: 316L stainless steel balls have better It is softer and tougher and white, so it is usually used for human body accessories.

Folding 201 stainless steel ball

Performance: Hardness ≤ 26 degrees, non-magnetic after demagnetization

Uses: Mainly used in general hardware accessories, household appliances accessories, stamping stainless steel, etc.

Application areas: 201 stainless steel balls are widely used in various hardware industries, handicrafts, and plastic products, such as lamps, switches, motorcycle accessories, luggage, bearings, and die-casting parts.

Characteristics: It belongs to nickel-saving steel, austenitic steel, non-magnetic, low price and excellent performance. Can be processed, welded, drilled, hardness HRC≤28.

Folding 302 stainless steel ball

Application areas: 302 stainless steel balls are widely used in auto parts, aviation, aerospace, hardware tools, and chemicals. The details are as follows: handicrafts, bearings, pulleys, medical equipment, posts, electrical appliances, etc.

Characteristics: 302 stainless steel ball belongs to austenitic steel, which is closer to 304, but the hardness of 302 is higher, HRC≤28. Has good rust and corrosion resistance.
