QR offer three type of 300 series stainless steel ball 302 304,316 They are high corrosion resistance feature, good resistance to alcohol, steam, oil, water ect that make them extensively used in a corrosive environment .

 

304 stainless steel ball

 

Characteristics: A typical representative of austenitic steel, generally non-magnetic, it will be magnetic after grinding, but can be demagnetized, HRC ≤ 26. Has good rust and corrosion resistance. Diameter Range: 0.5mm-2.0mm 3) Precision  Grade: G10-G1000  HRC 25-39

 

Application: 304 stainless steel ball is the most widely used steel ball on the market, 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.

 

Comparison: 304HC stainless steel ball is softer and easier to process than 304 stainless steel ball, and 304L stainless steel ball has stronger anti-rust and anti-corrosion performance than the above two. It is easy to be welded and has excellent surface. It is more suitable for industries with high standard of surface requirements.

 

316/316L Stainless steel ball

Characteristics: Austenitic 316 stainless steel ball is the highest grade product in steel ball industry which is most suitable for industries with high anti-corrosion requirements. All properties are better than 304 stainless steel balls. , no magnetic after degaussing, high corrosion resistance, non-corrosive
Hardness 25-39 HRC  Diameter Range : 1mm-180mm   Precision Grade: G40-G1000

 

Application: 316 stainless steel ball is a relatively high-standard product, usually used in special industries such as medical equipment, chemicals, aviation, aerospace: perfume bottles, sprayers, valves, nail polish, body jewelry, mobile phone panels.

 

Comparison: 316L stainless steel balls have  Softer and tougher characteristic , it is usually used for body jewelry.

 

302 stainless steel ball

Characteristics: 302 stainless steel ball belongs to austenitic steel, and is close to 304, but 302 has higher hardness, HRC ≤ 28. Have Good corrosion resistance

 

Application: 302 stainless steel ball is widely used in auto parts, aviation, aerospace, hardware tools, chemical industry. Specific as follows: crafts, bearings, pulleys, medical equipment, columns, electrical appliances and so on.
