Aluia 28he kila kila austenitic multi-purpose kiʻekiʻe no ka lawelawe ʻana i nā kūlana corrosive. Hōʻike ʻia ka papa e:
- Kiʻekiʻe loa i ka corrosion kūʻē i nā ʻakika ikaika
- ʻO ke kūpaʻa maikaʻi loa i ke koʻikoʻi corrosion cracking (SCC) a me ka intergranular corrosion ma nā ʻano kaiapuni
- Kūleʻa kiʻekiʻe i ka lua a me ka crevice corrosion
- Maikaʻi weldability

Ma muli o kāna mau waiwai corrosion koʻikoʻi, hiki ke hoʻohana ʻia ʻo Sanicro® 28 i nā ʻano like ʻole. Aia ma lalo iho nei kekahi mau la'ana o ka ho'ohana 'ana no ia mea i kūpono loa.
ʻakika Phosphoric
I kēia lā,Alloy 28 a i ʻoleʻO Sanicro 28 ka mea metala i hoʻohana nui ʻia no nā paipu evaporator i ka hana ʻana i ka waikawa phosphoric ma ke ʻano "mā". Ua lawelawe ʻia kekahi mau ʻāpana ma mua o 10 mau makahiki. ʻO nā mea hoʻololi wela graphite, i hoʻololi ʻia e Sanicro 28, ua loaʻa pinepine nā pilikia me nā paipu haki a me ka nalowale o ka hana.
ʻakika sulfuric
Alloy 28 a i ʻoleHe mea kūpono ʻo Sanicro 28 no nā paipu a me nā mea hoʻololi wela, ʻoi aku ka nui ma waena o 40 a me 70% o ka waikawa deaerated a ma luna o 85%.Alloy 28 a i ʻoleUa like like ko Sanicro 28 me ka Alloy C i loko o ka waika concentrated (98% H2SO4).
ʻAila a me ke kinoea
Alloy 28 a i ʻoleHoʻohana ʻia ʻo Sanicro 28 no ka hana ʻana i nā paipu, pahu a me nā laina i loko o nā pūnāwai kinoea hohonu. Hoʻomaopopo pū ʻia ka mea no nā pūnāwai aila me kahi kaiapuni corrosive. No kēia mau kumu, hoʻolako ʻia nā paipu i ʻōwili ʻia me ka ikaika kiʻekiʻe. Ma ke kūlana annealed solution,Alloy 28 a i ʻoleHoʻohana pū ʻia ʻo Sanicro 28 ma ke ʻano he paipu no ka lawe ʻana i ka ʻaila corrosive a me ke kinoea a no nā mea hoʻololi wela i nā keʻena lapaʻau. Hoʻohana ʻia nā laina laina ʻo Sanicro 28 no ka hoʻohaʻahaʻa ʻana i nā mea hana a me ka hoʻokele ʻana i nā mea kani i loko o nā luawai ʻaila hohonu a me ke kinoea.
Media e lawe ana i ka fluoride
Hiki ke hoʻokumu ʻia nā kinoea e lawe ana i ka fluoride i ka wā o ka hana ʻana i ka waikawa phosphoric a me nā mea hoʻohuihui. Pono e hoʻolei ʻia kēia mau kinoea no nā kumu kaiapuni. He kūpono ʻo Sanicro 28 no kēia kumu. Ua hōʻike ʻia nā hoʻāʻo ʻoi aku ka maikaʻi ma mua o nā māka CrNiMo i hoʻohui ʻia kiʻekiʻe no ka hoʻihoʻi ʻana i ka fluoride-bearing gypsum.
Nā mea kanu mana nuklea
Ma muli o kona kūpaʻa kiʻekiʻe i ka SCC, pitting a me ka ʻinoʻino, ua koho ʻia ʻo Sanicro 28 no nā mea hoʻololi wela i nā mea kanu nuklea.
Ka wai kai a me ka wai hooluu chloride
ʻO kona kūpaʻa kiʻekiʻe i ka lua a me ka crevice corrosion e hana ai ʻo Sanicro 28 i mea kūpono loa no nā paipu lawe wai kai a me nā mea hoʻololi wela hoʻoluʻu wai kai. Ua hōʻoia ʻia kēia e ka ʻike hana.
Ua hoʻololi ʻo Sanicro 28 i nā nickel alloys, CuNi, bimetallic tubes a me nā paipu kila kalapona i uhi ʻia, i hāʻule ʻole ma muli o ka corrosion. Ua maikaʻi ka hana o Sanicro 28.
I loko o nā mea hoʻololi wela i ka wai kai a me nā mea hoʻololi wela e hana pū ana me ka wai hoʻoluʻu chloride, hāʻawi ʻo Sanicro 28 i ke kūpaʻa kiʻekiʻe o ka corrosion i ka wai a me ke ʻano maʻalili.
Ke pani ʻia kahi mea kanu hoʻoluʻu wai kai, ʻaʻohe pono e hoʻokahe i ka ʻōnaehana paipu a holoi ʻia me ka wai hou, inā ʻoi aku ka pōkole o ka manawa pani ma mua o hoʻokahi mahina a ʻoi aku ka haʻahaʻa o ka wai ma mua o 30°C (85°F) .
ʻOi aku ka paʻa o ka duplex stainless steel 2507 ma mua o Sanicro 28 i ka wai kai.
