302 Stainless Steel balls provides extreme toughness and corrosion resistance from oxidizing solutions and many organic compounds in an unhardened state. In its annealed condition it withstands attacks by foodstuffs, dyes, sterilizing solutions and nitric acid. Not recommended for sulfuric or halogen applications. 302 is slightly magnetic.
