Difference Between AISI 440 and AISI 304:
AISI 440 and AISI 304 are two common materials for stainless steel bearings.
AISI 440 hardness can reach 58 after vacuum quenching decarburization treatment, suitable for use in weak acid-base and high-load environments.
Because of its high carbon content and magnetism, its corrosion resistance is not as good as AISI 304.
To sum up, bearings of AISI 440 can reach 1500RPM, hardness is 52-58HRC.
AISI 304 material contains large nickel content and low carbon content, therefore AISI 304 material is soft and has a hardness of about 25.
AISI 304 material bearings are not suitable for high-load rotation and are suitable for use in strong acid and alkali environments.
To sum up, bearings of AISI 304 is soft and non-magnetic, with Strong acid and alkali resistance and low revolving seed and low precision.
