Ka 2205 oka a (UNS S32305 / S31803) mea heʻelua papa kuhiliʻole kila oia hoi o ka 22% chromium, 3% molybdenum a me 5-6% nikala-naikokene oka a pau. Ua loaʻa kiʻekiʻe ikaika, maikai hopena toughness a me ka maikai nohona ma, a kūloko ia'ku i ka ikaika ka popopo.
Ke hoʻohālikelike me 316L a me 317L austenitic kuhiliʻole steels, 2205 oka a he oi ka popopo ia'ku, a crack e kū'ē'ē mai. Ua loaʻa kiʻekiʻe ka popopo ia'ku a me kona thermal? Anoe? Kaʻi lau waiwai mea haʻahaʻa ma mua ia o ka austenite. More moe.
Ke hoʻohālikelike me austenitic kuhiliʻole kila, ka mea, i ka compressive ikaika palua. Ke hoʻohālikelike me 316L a me 317L, i ke akamai ke ho'ēmi i kona kaumaha, a me ka waiwai e lilo aku i lalo.
Ka makamake nui hōʻuluʻulu manaʻo:
2205ʻelua papa kuhiliʻole Steel 2205 oka mea heʻelua papa kuhiliʻole kila oia hoi o ka 22% chromium, 3% molybdenum a me 5-6% nikala-naikokene oka a pau. Ua loaʻa kiʻekiʻe ikaika, maikai hopena toughness a me ka maikai a me ka nohona ma
hualoaʻa ia'ku e stress ka popopo.
Ke hoʻohālikelike me 316L a me 317L austenitic kuhiliʻole kila, 2205 oka a he kūlana hana i loko o ka pale aku plaque a me ka naele ka popopo. Ua loaʻa kiʻekiʻe ka popopo ia'ku a me kona thermal? Anoe? Kaʻi lau waiwai mea haʻahaʻa ma mua ia o ka austenite. More moe.
Ke hoʻohālikelike me austenitic kuhiliʻole kila, ka mea, i ka compressive ikaika palua. Ke hoʻohālikelike me 316L a me 317L, i ke akamai ke emi ke kaumaha, a no ia mea, ua kuu iho la i ka waiwai e lilo aku. Keia oka mea pakahi aku la ia e pono no ka hoʻohana 'ana i ka mahana huahelu o -50 ° F / +600 ° F, a ua hiki ke hoʻohana no ka haahaa mahana ma lalo loa kapu (oi loa aku hoi no ka welded hale).
Palapala noi kahua:
1.Pressure moku, kiʻekiʻe puʻe pūnaewele poʻina nalu, kiʻekiʻe puʻe pipelines, wela poe kuai moni (Nine Inch aaioee hana).
2.Oil a me ka kinoea pipelines, wela poe kuai pono.
3. Sewage lapaau nenoaiu.
4.Pulp a me ka pepa hana classifiers, ke loloʻa pono, pūnaewele aaioee nenoai.
5.Rotary mau pua, kaomi palapala, kōmi 'ana, impellers, etc. ma kiʻekiʻe-ikaika, ka popopo-hoʻopale hana kūpono.

Ka popopo ia'ku:
1.General ka popopo aie i kona chromium kiekie ae
Molybdenum a me ka naikokene maʻiʻo, 2205 ka ka popopo ia'ku mea i oi ke 316L a 317L ma ka hapanui hana kūpono
2. Local ka popopo e kū'ē'ē mai
Ka maʻiʻo o ka chromium, molybdenum a me ka naikokene i ka 2205ʻo ia ka mea i aloha hoʻopale i ka lepo a me ka naele ka popopo ma corrosive a me kaʻakika pāʻoihana.
Ka popopo hālawa 4 mpy (0.1 mm o / MH) i loko o kekahi sulfuricʻakika pāʻoihana i loaʻa ka 2000 ppm o koloriside
3. ka hoʻonaʻauao ka popopo e kū'ē'ē mai
Keʻelua papa microstructure o kuhiliʻole kila kōkua e hoʻomāhuahua kona ia'ku e stress naele ka popopo.
Koloriside stress ka popopo hiki ana ma ke alo o kekahi mahana, malihini, i oxygen a me chlorides. No ka mea, i kēia mau rula i ole e pono no ka hooponopono ana. I ka hoʻohana 'ana o 304L, 316L a me 317L ua kaupalena ia ma keia manao.
5.Fatigue ikaika ka popopo
Ke kiʻekiʻe ka ikaika a me ka popopo ia'ku o ka 2205 oka a haawi ia i ke kiʻekiʻe ia'ku i ka popopo a me ka luhi. ʻAno nui hoʻohana i ka hana kūpono me ka ikaika corrosiveness.
Ka pilikia ana wela o ka'aʻaiawāʻana i loko o 1M NaCl i ana ka hoʻohana 'ana i ka AvestaPolarit etched halepaahao.
Noho pilikia ana wela o ka māwae, ka popopo i ka 10% FeCl3 · 6H2O
