Duplex Stainless Steel 2205 Castings

2205 duplex zitsulo zosapanga dzimbiri ndi duplex zitsulo zosapanga dzimbiri zopangidwa ndi 21% chromium, 2.5% molybdenum ndi 4.5% nickel-nitrogen alloy. Mitundu ya ferrite ndi austenite iliyonse imakhala pafupifupi 50%. Lili ndi mphamvu zambiri, kulimba kwabwino komanso kulimba mtima kwapadziko lonse komanso kukana kupsinjika kwapanyumba. Mphamvu zokolola za 2205 duplex zosapanga dzimbiri ndizowirikiza kawirichitsulo chosapanga dzimbiri cha austenitic. Izi zimathandiza opanga kuchepetsa kulemera popanga zinthu, zomwe zimapangitsa kuti alloy iyi ikhale yotsika mtengo kuposa 316 ndi 317L. Aloyiyi ndi yoyenera kwambiri kutentha kwa -50°F/+600°F. Pazogwiritsa ntchito mopitilira kutentha uku, alloy iyi imathanso kuganiziridwa, koma pali zoletsa zina, makamaka zikagwiritsidwa ntchito pamipangidwe yowotcherera.

Magiredi Ofanana:
2205 duplex zitsulo, UNS S32205, NAS 329J3L, F51, W.-Nr. 1.4462, 00Cr22Ni5Mo3N

Miyezo Yoyang'anira:
ASTM A240/ASME SA-240, ASTM A276, ASTM A182/ASME SA-182, ASTM A312/ASMES A312

Katundu Wathupi:

• Kulemera kwake: 7.98 g/cm3
• Malo osungunuka: 1300 - 1390 ℃

Njira Yochizira Kutentha:
Gwirani kutentha kwapakati pa 1000 - 1050 ℃ kwa maola 1-2, kuzizira kwa mpweya kapena kuziziritsa kwamadzi.

Katundu Wamakina:

• Kuthamanga Kwambiri: σb≥795Mpa
• Kuchuluka Kwambiri: σb≥550Mpa
• Elongation: δ≥15%
• Kulimba ≤310 (HB)

Kukaniza kwa Corrosion ndi Kugwiritsa Ntchito Malo:
Poyerekeza ndi 316L ndi 317L austenitic chitsulo chosapanga dzimbiri, 2205 duplex chitsulo chosapanga dzimbiri chili ndi ntchito yabwino kwambiri yolimbana ndi dzimbiri komanso kuphulika kwa minga. Ili ndi kukana kwambiri kwa dzimbiri. Poyerekeza ndi austenitic, ake The coefficient of thermal expansion ndi otsika ndipo matenthedwe conductivity ndi apamwamba. Poyerekeza ndi chitsulo chosapanga dzimbiri cha austenitic, chitsulo chosapanga dzimbiri cha duplex 2205 alloy chimakhala ndi mphamvu zopondereza kawiri. Poyerekeza ndi 316L ndi 317L, wopanga akhoza kuchepetsa kulemera kwake. Aloyi 2205 makamaka oyenera kutentha osiyanasiyana -50°F/+600°F. Pansi pa zoletsa zokhwima (makamaka zomangidwa ndi welded), zitha kugwiritsidwanso ntchito pa kutentha kochepa.

Mapulogalamu a 2205 DSS Castings:

• Zida zamakampani amafuta ndi gasi;
• Mapulatifomu akunyanja, zosinthira kutentha, zida zapansi pamadzi, zida zozimitsa moto;
• Chemical processing makampani, ziwiya ndi makampani mapaipi;
• Kuchotsa mchere, zida zothamanga kwambiri za RO ndi mapaipi apamadzi apamadzi;
• Makampani opanga mphamvu monga magetsi desulfurization ndi denitration FGD system, mafakitale scrubbing system, mayamwidwe nsanja;
• Ziwalo zamakina (zamphamvu kwambiri, zolimbana ndi dzimbiri, zosavala)
