The main components of ASTM A213 304 stainless steel coil include carbon, manganese, silicon, chromium and nickel.
In terms of manufacturing process, 304 stainless steel coil is mainly manufactured by cold drawing and hot rolling. The cold drawing process can improve the dimensional accuracy and surface quality of the pipe, while the hot rolling process is suitable for manufacturing large-diameter and thick-walled pipes.
The application fields are wide, including chemical, petroleum, pharmaceutical, aerospace and other fields. In the chemical industry, 304 stainless steel coil is used to transport various dilute acids, concentrated acids, hydrochloric acid, sodium hydroxide and other media; in the petrochemical industry, it is used to transport high-temperature and high-pressure oil and natural gas; in the pharmaceutical field, it is used to transport various liquid medicines and perform filtering operations; in aerospace, it is used to manufacture aircraft engine exhaust pipes and hydraulic pipelines, etc.
