2205 duplex kila kila

ʻO ka haku mele: 22% chromium, 5% nickel, 3% molybdenum, a me 0.18% nitrogen. Mechanical waiwai: Tensile ikaika: 620MPa, Hua ikaika: 450MPa, Elongation: 25%.

Kū'ē kū'ē: He kū'ē kū'ē maikaʻi loa ia a he kūpono ia no nāʻano media corrosive, e like me ka waikawa, ka alkali, ka paʻakai, a me nā mea'ē aʻe.

ʻano:

Palekana oxidation: 310S ke kila kila maikaʻi ka pale ʻana i ka oxidation a hiki ke mālama i ke kūpaʻa i nā wahi wela kiʻekiʻe.

ʻO ke kūpaʻa ʻino: Ma muli o kona kiʻekiʻe o ka chromium a me ka nickel content, 310S stainless steel he kūpaʻa kūpaʻa maikaʻi a kūpono ia no nā ʻano ʻano corrosive.

Kiʻekiʻe paakiki martensitic kuhiliʻole kila hana hoʻoheheʻe paipu ua nui hoʻohana 'ia no ka ikaika kiʻekiʻe a me ka paakiki noi, a koi i kekahi corrosion kū'ē. Ua kapa ʻia ʻo Martensitic stainless steel no kona paʻakikī kiʻekiʻe a me ka ikaika ma hope o ka mālama ʻana i ka wela, a kūpono ia no ka hana ʻana i nā mea ʻokiʻoki, nā punawai, nā bearings, nā valves, nā kino pump a me nā ʻāpana ʻē aʻe.

ʻO 904L ke kila kila he kila kila nui austenitic me ke kūpaʻa corrosion kiʻekiʻe loa, ʻoi aku ka nui o nā wahi i loaʻa nā chlorides.

C276/S32760 (Hastellloy C-276)

ʻO ka haku mele: C276 alloy ka nui o ka nickel (ma kahi o 59%), a me ka molybdenum, chromium, tungsten a me nā mea ʻē aʻe. Hōʻike pinepine ʻia kona ʻano kemika e like me 00Cr15Ni60Mo16W4.

Hastelloy GH3044

ʻO ka hui kemika: ʻO GH3044 kahi hopena paʻa paʻa nickel-chromium i hoʻoikaika ʻia i ka superalloy, nona ka chromium kiʻekiʻe a me ka tungsten content, a me kahi liʻiliʻi o ka molybdenum, hao, alumini a me nā mea ʻē aʻe.

ʻO ka hui kemika: ʻO Incoloy 800 he nickel-iron-chromium alloy i loaʻa i kahi kiʻekiʻe o ka nickel (e pili ana i 30-35%), chromium (e pili ana i 19-23%) a me ka hao (e pili ana i 39-45%).

ʻO ka haku mele: NO6600 he nickel-chromium-iron-based solid solution reinforced alloy i loaʻa ka nickel, chromium, hao a me nā mea ʻē aʻe. Hiki i nā mea kiko'ī ke komo i ka nickel (e pili ana i ka palena), chromium (e pili ana i 19-23%), hao (ma kahi o 5-10%), a me kahi mea liʻiliʻi o ka carbon, manganese, silicon, etc.

ʻO TP316L ʻO ke kila kila kila he ʻano mea kila kuhili ʻole austenitic, aia ia i ka moʻo 316, kahi i hōʻike ʻia ai ka "L" i ke kalapona haʻahaʻa (Low Carbon). He kūpono loa kēia mea no ka hoʻohana ʻana i nā kūlana e koi ʻia ai ka wili ma muli o kāna mau waiwai wili maikaʻi a me ke kūpaʻa corrosion. Hoʻohana nui ʻia ʻo TP316L Stainless steel welded pipe i ka ʻoihana kemika, ka ʻaila, ka hana meaʻai, ka lāʻau lapaʻau, ka hana pepa, ka ʻenehana moana a me nā ʻoihana ʻē aʻe.

ʻO TP316Ti Stainless steel welded pipe he mea austenitic stainless steel, nona ka 316 series, aia ka titanium ma ke ʻano he mea hoʻokū. He mea kūpono loa kēia mea no ka hoʻohana ʻana i nā kaiapuni kiʻekiʻe a me nā corrosive, e like me ke kemika, ka ʻaila, ka hoʻoili ʻana i ka meaʻai, ka lāʻau lapaʻau, a me nā ʻoihana ʻē aʻe. TP316Ti ʻO ka titanium stabilization o ke kila kila welded paipu e kōkua i ka pale ʻana i ka intercrystalline corrosion, ʻo ia ke kumu o ka pilina ikaika o ka titanium a me ke kalapona, a me ka hui pū ʻana me ke kalapona e hana i ka titanium carbide paʻa, i mea e pale ai i ke kūkulu ʻia ʻana o ka chromium carbide ma ka palena o ka palaoa a pale i ka pale ʻana o ka mea.

ʻO 15X25T he kila kila, "15" kahi kalapona ma kahi o 0.15%, "X" e hōʻike ana i ka ʻike o nā mea hoʻohuihui, a ʻo "25 T" e hōʻike ana he 25% o nā mea hoʻohuihui. Ma ke kūlana Lūkini, pili kēia ʻano kila i ka ʻāpana o ke kila structural alloy a hoʻohana maʻamau ʻia e hana i nā ʻāpana mechanical e kū i nā ukana kiʻekiʻe a me nā hopena.

Anti-intercrystalline corrosion: Ma muli o ka hoʻohui ʻana o ka titanium, hiki i ka TP 321 stainless steel welded pipe ke pale aku i ka corrosion intercrystalline, ma muli o ka pili ikaika o ka titanium a me ke kalapona, i hui pū ʻia me ke kalapona e hana i kahi carbide titanium paʻa, pēlā e pale ai i ka hoʻokumu ʻia ʻana o ka chromium carbide, a me ka pale ʻana i ka mea aniani.
