1. Products Details
2205 is a duplex (austenitic-ferritic) stainless steel containing
about 40 - 50% ferrite in the annealed condition. 2205 has been a
practical solution to chloride stress corrosion cracking problems
experienced with 304/304L or 316/316L stainless. The high chromium, molybdenum and nitrogen contents provide
corrosion resistance superior to 316/316L and 317L stainless in
most environments.
2205 is not suggested for operating temperatures up to 600°F.
The design strength of 2205 is significantly higher than 316/316L,
often permitting lighter wall construction.
2205 has good notch impact toughness down to temperatures below -
40°F. 2205 is welded with E2209 or ER2209 fillers.

tanks, piping, and heat exchangers
2). Oil and gas exploration and processing equipment – piping,
tubing, and heat exchangers
3). Marine and other high chloride environments
4). Effluent scrubbing systems
5). Pulp and paper industry – digesters, bleaching equipment, and
stock-handling systems

4. Production Flow about stainless steel sheet
A. Raw materials are sending to hot rolling units for rolling into
different sizes
B. Hot rolled material is annealing in cold; rolled annealing furnace and pickling in acid.
C .All mill rolls are grinded on precision grinding machine with
proper chamfering after first shiftoperation.
D .All sheets are pickled in different tanks and dried on brush
roll machine before dispatched.
E. These sheets are again annealing and are sent to straighten
machine for straightening.
F. Inspections are done at various stages. Keep proper control
overall internal process via rolling,annealin and pickling by our
experienced staff.
5. Packaging of stainless steel sheet
We wrap the stainless steel products with anti-rust paper and steel
rings to prevent damage. Identification labels are tagged
accordingto standard specification or customer's instructions.
Special packing is available as per customer's requirement.
