What are the advantages of Stainless Steel Inner Balls made of other materials?

Stainless steel inner beads contain a high content of chromium, usually above 12.5%, which enables stainless steel to form a dense chromium oxide layer on the surface. This oxide film effectively blocks the contact between steel and air, preventing oxygen, moisture and chemicals in the air from corroding the steel. In contrast, ordinary steel such as carbon steel balls are prone to rust and corrosion in humid or corrosive environments, resulting in a shortened service life. Stainless steel inner beads can maintain a longer service life in these harsh environments, reducing the cost of repair and replacement due to corrosion.
Stainless steel materials themselves have high strength and hardness, which enables stainless steel inner beads to maintain good shape and performance when subjected to impact and wear. Although bearing steel balls perform well in hardness and wear resistance, stainless steel inner beads are better in rust and corrosion resistance.
The surface of stainless steel inner beads is usually specially treated with polishing, sandblasting, etc. These treatment processes can make the surface smoother and flatter and reduce the friction coefficient. The smooth surface reduces friction and wear during use, thereby improving the durability of the inner beads. In addition, some stainless steel inner beads also use advanced technologies such as chemical plating and physical vapor deposition to further improve their surface hardness and wear resistance.
Some stainless steel inner beads are non-magnetic or extremely low in magnetism after demagnetization, which makes them suitable for occasions with strict requirements on magnetism, such as electronic equipment, nuclear magnetic resonance imaging, etc. The corrosion resistance, wear resistance, and non-magnetic properties of stainless steel inner beads enable them to be used in a variety of machinery and equipment, including aerospace, bearings, motors, high-precision instruments, valves, petroleum and other fields.
Stainless steel inner beads are available in a variety of materials, such as 304, 316, 316L, 420, 440C, etc. Each material has its unique properties and applicable occasions. 304 stainless steel has good rust resistance and is suitable for general corrosive environments. 316 stainless steel has stronger rust resistance and is suitable for harsher environments such as seawater and chemical industry. 440C stainless steel has high hardness and good wear resistance, and is suitable for occasions with high requirements for precision and rust resistance. Users can choose the appropriate stainless steel material according to the specific use environment and requirements to meet different performance requirements.
