Finished Annealed High Corrosion Resistance
904L (N08904, 1.4539) super austenitic stainless steel contains
14.0-18.0% chromium, 24.0-26.0% nickel and 4.5% molybdenum.904L super austenitic stainless steel is a low carbon, high nickel,
molybdenum austenitic stainless steel, which is a special material
introduced from H·S Company in France.It has good activation-passivation transformation ability and
excellent corrosion resistance. It has good corrosion resistance in
non-oxidizing acids such as sulfuric acid, acetic acid, formic acid
and phosphoric acid. It has good pitting resistance in neutral
medium containing chloride ions, and has good crevice corrosion
resistance and stress corrosion resistance.It is suitable for various concentrations of sulfuric acid below
70℃. It is resistant to acetic acid at any concentration and at any
temperature under atmospheric pressure, and the corrosion
resistance of mixed acid of formic acid and acetic acid is also
very good.
Super Austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu, N08904,
1.4539) is a high alloy austenitic stainless steel with low carbon
content and excellent corrosion resistance in dilute sulfuric acid,
designed for harsh corrosion conditions.Has the high chromium content and plenty of nickel content, the
addition of copper makes it have strong ability to resist acid,
especially for chloride clearance corrosion and stress corrosion
cracking are highly resistant, not easy to appear, erosion and
fracture pitting resistance slightly better than other steel grade,
good machinability and weldability, can be used for pressure
vessels.

Coil Slitting Mill Capability :
Striping processing, commonly known as “slitting “, refers to the
winding of a metal coil by unwinding, slitting, leveling, winding,
and processing into a desired width. Slitting processing is a basic
metal processing technology that combines high-quality equipment
with skilled craftsmanship. it can be obtained with strict
tolerance, perfect surface control , safe packaging as well as fine
transportation.

Stainless Steel Coil Grade 904L UNS N08904 Technical datasheet
Possible alternative grades to grade 904L stainless steels
Grade | Reasons for choosing grade 904L |
316L | A lower cost alternative, but with much lower corrosion resistance. |
6Mo | A higher resistance to pitting and crevice corrosion is needed. |
2205 | A very similar corrosion resistance, with the 2205 having higher
mechanical strength, and at a lower cost to 904L. (2205 not
suitable for temperatures above 300°C.) |
Super duplex | Higher corrosion resistance is needed, together with a higher
strength than 904L |

Heat Treatment
Annealing: The recommended annealing temperatures for 904L wrought
steel is 1095 °C (2000 °F).
Corrosion
Type 304 stainless steel can handle mild foods and vegetables, but
sauces and pickle liquors are more corrosive and can even cause
pitting corrosion on type 316 stainless steel. In order to improve
pitting resistance, high alloy 904L stainless steel (SS904L) should
be considered.
Applications
904L stainless steel (SS904L) is used in petroleum, chemical,
fertilizer, marine development towers, tanks, pipes and tubes and
heat exchangers. Rolex and other watch manufacturers also use it to
make watches.
