2205 Duplex Stainless Steel Fasteners

Triton Alloys Inc manufactures Duplex 2205 hex bolts, nuts, and screws to your custom specifications, and we guarantee to meet your delivery schedule. The high strength that makes Duplex 2205 useful in many applications unfortunately reduces its machinability. Cutting speeds are approximately 20% slower than for grade 304. The strength of Duplex 2205 also makes bending and forming more difficult; requiring larger capacity equipment than for austenitic stainless steels.

Duplex 2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. The Duplex 2205 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 2205 alloy exceeds those of types 316L and 317L stainless steels. When heat-treated properly, the composition of AL 2205 alloy produces a microstructure that consists of a nearly equal mixture of austenite and ferrite phases.
