According to the chemical composition, stainless steel bearings can be classified into AISI 304, AISI 316L AISI 440C, etc. different grades. They have different characteristics and applications.
Let's introduce the detailed difference below!
AISI 304 is an austenitic stainless steel. The main components of AISI 304 are iron, chromium (18-20%), nickel (about 8-10.5%), a small amount of carbon (usually ≤0.08%), and manganese, phosphorus, silicon, etc. elements.
AISI 316L mainly consists of iron, chromium (16-18%), nickel (10-14%), molybdenum (2-3%), lower carbon (less than 0.03%), and phosphorus, manganese, silicon, etc. elements. It is also an austenitic stainless steel.
AISI 440C is a martensitic high-carbon stainless steel, mainly composed of iron, chromium (16-18%), carbon (0.95-1.2%), a little nickel, and silicon, phosphorus, manganese, etc. elements.
Corrosion resistance: AISI 304 has good corrosion resistance. This type of stainless steel material is suitable for humid environments. However, It isn't suit for use in such as seawater or salty air, etc. chloride environments.
Moderate strength: AISI 304 has moderate strength and good mechanical properties. Thereby they are suitable for light load applications.
Processability: AISI 304 is easy to process and weld.
Corrosion resistance: AISI 316L has stronger corrosion resistance compared with AISI 304. Especially in such as seawater or chemical processing etc. chloride environments.
Strength: The strength of AISI 316L is similar to 304, but 316L has better resistance to high temperatures and pressures due to the presence of molybdenum.
Low carbon content: AISI 316L suits for welding applications, because it reduces carbide precipitation during welding.
Hardness and strength: AISI 440C is one of the hardest stainless steels. It has very high hardness and strength.
Corrosion resistance: AISI 440C has slightly lower corrosion resistance compared with 304 and 316L. However, it still has certain corrosion resistance in the hardened state.
Wear resistance: 440C stainless steel exhibits good wear resistance due to its high hardness and strength. This makes it suitable for high-load and wear environments
AISI 304 material is often used for bearings that do not require extremely high strength or wear resistance due to it has corrosion resistance, affordability, and balanced strength. So the 304 stainless steel bearings are usually used in those applications including mildly corrosive environments such as kitchen equipment, food processing, chemical processing, construction, and so on.
AISI 316L material is often used in more corrosive environments such as chemical, marine, medical equipment, etc. Because it enhances corrosion resistance in chloride-rich environments.
AISI 440C is often used in such as aerospace, automobiles, etc. high-precision, heavy-load, and high-wear environments. Because it has slightly poor corrosion resistance, high hardness and strength, etc. advantages.
AISI 304: AISI 304 is widely used, it can be used in general corrosion-resistant environments, moderate strength, and economical.
AISI 316L: AISI 316L has better corrosion resistance, especially suitable for more demanding chemical and marine environments.
AISI 440C: AISI 440C has outstanding hardness and wear resistance, but relatively weak corrosion resistance. It is suitable for high-load and high-precision occasions.
