SUS304L | Austenitic Stainless Steel

Overview & Features

SUS304L is the extra low carbon of typical austenitic stainless steel SUS304.
It has a lower carbon content than SUS304 and has particularly excellent intergranular corrosion resistance. It is also suitable for deep drawing due to its low hardness in the annealed finish and low work hardening.
*The "L" in SUS304L stands for low carbon.

Mechanical Properties

The table below shows approximate values of mechanical properties for annealed/2B finish and full hardened finish.
We can manufacture products in the desired hardness (finish) between annealed finish and full hardened finish, but some finishes may not be available depending on the plate thickness, so please contact us first. *For ultra-thin foil, soft materials such as annealed or 2B finish may not be applicable due to concerns about defects (folding, wrinkling, etc.).

Ultrafine Grain Stainless Steel
nanoSUS™

nanoSUS™ a stainless steel in which the crystal grain size of the material is refined to about 1μm. The control of microstructure contributes to improving various properties such as strength, fatigue properties, and workability."
