To better understand each type of commonly used stainless steel and its properties, see the following descriptions.

  • 440C Stainless Steel is a high carbon martensitic stainless steel. It has high strength, medium corrosion resistance, good hardness, and wear resistance
  • 304 Stainless Steel is the most widely used stainless steel. It is austenitic stainless steel and has a higher corrosion resistance than ordinary steel.
  • 316L Stainless Steel is also austenitic stainless steel. It offers higher corrosion resistance than 304.
  • 201 Stainless Steel is the least expensive type of stainless steel. It is tough in cold environments but has lower corrosion resistance. It is the preferred choice for applications that require low cost, high durability, and no concern for exposure to corrosive elements.

They worked great for what I was using them for with some projects, but for rebuilding small stainless bearings, I'd probably find different higher quality bearings that are actually 304 stainless. 304 stainless steel isn't magnetic these bearings stick to magnetics pretty well...
