This type of stainless is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Unlike some stainless steel, this 400 series metal has a composition which allows it to be attracted to a magnet.

What can I say, it's a steel ball. It should do exactly what I bought a steel ball to do.

But my intention was to drill and tap it to be a ball end for a RAM mount system.FAIL! The ball is too hard to be drilled. In my lathe, I could hardly make a scratch on the surface. Even flattening a bit with a grinder, the drill bit still couldn't cut into it.So I'm giving the product 5 stars. I'm giving myself 1 star for my failure to machine it. (snicker)

I bought these to weigh down bags in sous vide applications. Stainless steel so I don't have to worry, and they clean up easily afterwards.

People that are buying these for use with cooking/brewing/etc applications and then giving a poor review when they discolor don't understand stainless steel. These are 440, says so in the description, apparently everyone is missing that and just seeing "stainless steel". 440 IS NOT food grade by design, it's only rated for moderate corrosion resistance. If you're looking for food grade you need 304.Educate yourselves.

The perfect solution for keeping food below the water line in Sous Vide cooking. they don't rust or stick to the food. We used 10 balls and that works for steaks, pork tenderloin etc. We started with 5 but needed more for some of the larger meats. 5 more was the answer.
