Materyal ng produkto
Ang Alloy 2205 (UNS S32305/S31803) ay isang 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel na may mataas na general, localized, at stress corrosion resistance properties bilang karagdagan sa mataas na lakas at mahusay na impact toughness.
Ang Alloy 2205 duple steel ay nagbibigay ng pitting at crevice corrosion resistance na higit sa 316L o 317L austenitic stainless steel sa halos lahat ng corrosive media. Mayroon din itong mataas na corrosion at erosion fatigue properties pati na rin ang mas mababang thermal expansion at mas mataas na thermal conductivity kaysa austenitic.
