rength that makes 2205TM useful in many
applications unfortunately reduces its machinability. Cutting
speeds are approximately 20% slower than for grade 304. The
strength of Duplex 2205TM also makes bending and
forming more difficult; requiring larger capacity equipment than
for austenitic stainless steels. Atlanta Rod has the capacity
and equipment to handle all of your Duplex 2205TM
projects.
2205TM
is the most widely used duplex (ferritic/austenitic) stainless
steel grade. The Duplex
2205TM
alloy is a nitrogen-enhanced duplex stainless steel alloy. The
nitrogen serves to significantly improve the corrosion
resistance of the alloy; especially in the welded condition.
The typical high Cr, Mo and Ni contents of AL 2205 alloy give it
a high PREN (Pitting Resistance Equivalent) of 35.8, further
enhancing its corrosion resistance. The PREN of AL 2205TM
alloy exceeds those of types 316L and 317L stainless steels.
When heat-treated properly, the composition of AL 2205TM
alloy produces a microstructure that consists of a nearly equal
mixture of austenite and ferrite phases.
The microstructure and composition of the AL 2205TM
alloy provides corrosion resistance to many environments that is
superior to Types 316 or 317, and a minimum yield strength that
is more than double that of conventional austenitic stainless
steels. The microstructure and phase balance of AL 2205TM
alloy have been designed to facilitate the production of pipe
and tube products. All AL 2205TM
alloys are metallographically examined to ensure that the
as-shipped product is essentially free from the presence of
detrimental precipitate phases such as sigma.
