304L Stainless Steel Strip Coil

Type 304L (UNS S30403) stainless steel strip coil has an extra-low carbon content and is a variation of Type 304. The low carbon content is necessary for welding applications where avoiding carbide precipitation is key. Additionally, due to the low carbon content, Type 304L has lower mechanical properties than Type 304.

304L SS Strip Coil Applications:

304L stainless steel strip coil is mainly used in welding applications where corrosion resistance is a concern. For example, it is frequently used in automotive fuel lines and other tubing applications.

Magnetic Properties:

304L stainless steel flat rolled coil is generally non-magnetic and becomes slightly magnetic only when cold-worked.

Forming:

Type 304L has good drawability and can be formed into many complex shapes.
