Surface:
Generally can be divided into 304 stainless steel light round (referred to as: 304 light round, 304 light rod, or 304 stainless steel silver bright rod) and 304 stainless steel black round (referred to as: 304 black rod, or 304 stainless steel rod).
304 stainless steel light round, refers to the surface is smooth, after rolling, peeling or cold drawing polishing process processing; Commonly used in various chemical, food, textile and other machinery and equipment and certain decorative purposes. And the so-called 304 stainless steel black round or 304 stainless steel bar (black bar), refers to the surface of black rough, hot rolling, forging or annealing process, do not deal with the surface of the oxide layer of the round steel.

304/304L is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, and to many chemicals and food and beverages. These grades can be specified in the annealed condition where they have very good formability.
304/304L is non-magnetic in the annealed condition but may become slightly magnetic as a result of cold working.
