304L Alloy Description
Alloy 304L is an extra low-carbon variation of 304 making it useable in the “as-welded” condition (without annealing), even in severe corrosive conditions. The alloy has oxidation resistance to a maximum temperature of 1650°F (899°C) continuously without appreciable scaling. The maximum temperature for intermittent exposure is 1500°F (816°C).

304L can be cold rolled to various tempers. Contact Ulbrich Wire Technical Service for additional information
Corrosion Resistance Refer to NACE (National Association of Corrosion Engineers) for recommendations.
Standard Wire Finishes
Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”
Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications
Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products.
Plated: Many plating options are available.
∗Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
Cut to lengths
Cold Forming Alloy 304L is ductile and can be cold worked by stamping, drawing, bending or forming methods.
Heat Treatment Alloy 304L cannot be heat treated for hardness. Hardness can only be achieved by cold working.
Welding Refer to SSINA’s ‘Welding of Stainless Steels and Other Joining Methods’ for best practices.
