AISI 304/304L Stainless steel capillary coiled tubing  AISI 304 stainless steel coil is an all-purpose product with excellent resistance and it is suitable for a wide variety of applications that require good formability and weldability. Sheye Metal stocks 304 coils in 0.3mm to 16mm thickness and 2B finish, BA finish, No.4 finish are always available. Beside the three kinds of surfaces, 304 stainless steel coil can be delivered with a variety of surface finishes. Grade 304 stainless contains both Cr (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents. This type of coils is an typically austenitic stainless steel, belongs to the standard Cr-Ni stainless steel family. They are typically used for household and consumer goods, kitchen equipment, indoor and outdoor cladding, handrails, and window frames, food and beverage industry equipment, storage tanks.
