The raw material of the stainless steel ball is stainless steel, the type of stainless steel is different, the performance and application field of the stainless steel ball manufactured are also different. What are the main applications of stainless steel balls made of 400 series stainless steel? Changzhou Feige Steel Ball Manufacturing Co., Ltd. provides you with relevant details about 400 series stainless steel balls.
1. Stainless steel ball 440:
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
Specification: Φ1.0—Φ30
2.440C stainless steel ball
Application areas: 440C stainless steel balls are usually used in industries that require high accuracy and rust resistance: aviation, aerospace, bearings, motors, high-precision instruments, valves, petroleum.
Special characteristics: The metallographic structure is a martensitic steel, and the production process requirements are relatively high. There are few domestic companies that can produce 440C stainless steel. Therefore, companies that can produce 440C materials are often referred to as special stainless steel. The heat treatment process is more complicated, easy to crack, and requires higher 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 rust and corrosion resistance than the former.
Comparison: Compared with the 440 stainless steel ball, it has stronger anti-rust and anti-corrosion performance, the hardness is enhanced, and the wear resistance is also improved.
3. Stainless steel ball 420
Performance: Hardness reaches 51-52 degrees, magnetic, with 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 corrosion by the atmosphere, water vapor, water and oxidizing acids.
Specification: Φ2.0—Φ25.4
420 stainless steel ball application field: 420 stainless steel ball is usually used in industries that require high precision and anti-rust performance: motorcycle accessories, pulleys, stainless steel bearings, plastic bearings, handicrafts, valves, petroleum.
Special characteristics: Representative of martensitic steel, commonly known as stainless iron, magnetic, good rust resistance, high hardness HRC50-55.
