Alloy 2205 Fasteners

Alloy 2205 is a Duplex stainless with 40-50% austenite and 50-60% ferrite.

It surpasses 317L in crevice corrosion resistance and excels in chloride environments.

Resists hydrogen sulfide and has almost twice the strength of 316L.

Used in pressure vessels, heat exchangers, and scrubbers.

Navratna stocks hex bolts (1/4" to 1") and maintains nuts, washers, rods, and some socket screws.

Stock: Hex bolts, nuts, washers, threaded rods; socket screws (limited).
