A package of 5 3/4 inch (.75") 304 stainless steel balls. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. 304 Sainless steel (also known as A2 stainless steel or 18/8 stainless steel, European norm 1.4301) is the most common stainless steel. The steel contains both chromium (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents. It is an austenite steel. It is not very electrically or thermally conductive, and is non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. It contains 17.5-20% Chromium, 8-11% Nickel, and less than 0.08% Carbon, 2% Manganese, 1% Silicon, 0.045% Phosphorus, and 0.03% Sulfur 304 Stainless Steel has excellent resistance to a wide range of atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. It is considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60°C. 304 stainless steel is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and fabrics.
