Manufacturing stainless steel strip is a multi-step process. First, the raw materials are melted together in an electric furnace for 8 to 12 hours, until they reach their recrystallization temperature. The molten steel is then cast into semi-finished forms called blooms, billets, slabs, rods and tube rounds. The unfinished shapes then undergo a forming process such as cold rolling, in order to become stainless steel strip.

The cold rolling process is not done at temperatures that are generally considered cold, but at temperatures that are below the recrystallization temperature of the metal. During the cold rolling process, stainless steel strip is pulled between rollers in order to be compressed and squeezed into the desired shape, which for strip is very thin with a length that is many times its width.

Heat-treatable stainless steel can also be hot rolled, which is generally the same process except the process is done at temperatures that are above the recrystallization temperature of the metal. The most common grades used to form stainless steel bars include 304 and 316. The 300 series are types of austenitic stainless steel, meaning that they are useful in mild, harsh and corrosive environments as well as being non-magnetic.
