Materials lead to different uses of stainless steel ball

Stainless steel ball is a member of the steel ball family, but stainless steel ball also has its own family, stainless steel ball also may continue to distinguish the same, it is because the beginning of the stainless steel ball forging process produced Do you know what types of stainless steel balls are commonly seen nowadays? If you still do not know it, let's take a look at this editor.

440C stainless steel ball

Performance: Hardness of 56-58 degrees, a magnetic, corrosion resistance, wear resistance and toughness of the stainless steel ball massage machine strong toughness: mainly used in bearings, stamping / hydraulic parts, valves, seals, refrigeration equipment, aerospace High-precision mechanical parts, handicrafts, toys.

Applications: 440C stainless steel ball pass often used for precision and stainless steel ball cell phone board rust performance requirements are relatively high sectors: aviation, aerospace, bearings, motors, high precision instruments, valves, oil.

Characteristics: The metallographic structure is classified as martensitic steel. The production process is relatively demanding. There are relatively few domestic enterprises that can produce 440C stainless steel, so the enterprises that produce 440C materials are often honored with the same kind of stainless steel. Heat treatment process is more complicated, easy to crack, and precision nail polish stainless steel ball requirements are relatively high, is the hardest steel ball in a stainless steel ball: HRC ≧ 58. Similar hardness bearing steel ball, but stronger than the former rust and corrosion resistance.

420 stainless steel ball

Performance: hardness 51-52 degrees, a magnetic, a certain degree of corrosion resistance and toughness Use: Suitable for all types of precision machinery, bearings, electrical equipment, transportation tools, household appliances and so on. Multi-purpose system in the manufacture of resistance to the atmosphere, water vapor, water and oxidizing acid corrosion parts.

Characteristics: The representative of martensitic steel, also known as stainless iron, magnetic, better anti-rust performance, high hardness HRC50-55.

Stainless steel ball304 / 304HC

Use: Mainly used in medical equipment, baby bottles

Features: A typical austenitic steel representatives, the general non-magnetic, but after passing through the ball will be magnetic, can be demagnetized, HRC ≤ 26. With excellent anti-rust, anti-corrosion properties.

Stainless steel ball316 / 316L

Performance: hardness ≤ 28 degrees, non-magnetic degaussing, anti-rust ability, non-corrosive

Use: Mainly used in medical equipment, food machinery, cosmetics accessories, body jewelry, instrumentation, etc.

Features: austenitic steel, the current steel ball industry in the most upscale, HRC ≤ 26, the best anti-corrosion requirements of the higher the industry, each performance is better than 304 stainless steel ball comparison: 316L stainless steel ball more With softer and more white, so often used for human jewelry.

302 stainless steel ball

Use areas: 302 stainless steel steel ball commonly used in auto parts, aerospace, aerospace, hardware, chemicals. Details are as follows: crafts, bearings, pulleys, medical equipment, then column, electrical appliances and so on.

Features: 302 stainless steel steel ball classified in austenitic steel, and 304 similar, but a little higher hardness of 302, HRC ≤ 28. With excellent rust and corrosion resistance.

Above different types of stainless steel ball can be used in different industries, everyone in the purchase of stainless steel ball occasion, we must first understand what you want to buy a stainless steel ball industry.
