304 stainless steel bearings are a common type of stainless steel bearing. They have better corrosion resistance than 440C stainless steel bearings, but they are cheaper than 316 stainless steel bearings.
The current chemical equation for 304 stainless steel is Cr19Ni10, which contains 19% chromium and 8-10% nickel. The older equation was Cr18Ni9.
304 stainless steel is one of most widely used nickel-chrome stainless steels. It has good corrosion and heat resistance, low temperature strength, and good mechanical properties. However, in heavily polluted industrial air, this metal requires regular cleaning maintenance in order to avoid corrosion. This metal is used in food processing, storage, transportation, plate heat exchangers, corrugated pipes, home appliances, building materials, chemicals, etc. because of its excellent processing performance and weldability. 304 stainless steel is food-grade stainless steel that is recognized by many countries.
