ʻO 310S/309S maikaʻi loa ka pale ʻana i ka corrosion a hiki ke kū i nā wela kiʻekiʻe a hiki i 980°C.Hoʻohana maʻamau i ka paila, ʻoihana kemika a me nā ʻoihana ʻē aʻe.Ke hoʻohālikelike ʻia me 309S, ʻaʻohe sulfur (S) maʻiʻo i ka 309.
310s Papa kila kila
ʻO ka helu like ma Kina ʻo 06Cr25Ni20, i kapa ʻia ʻo 310s ma ʻAmelika Hui Pū ʻIa a pili i nā kūlana AISI a me ASTM.Hoʻopili pū ia me JIS G4305 maʻamau "sus" a me ka maʻamau ʻEulopa 1.4845.
ʻO kēia chromium-nickel austenitic stainless steel, i kapa ʻia ʻo 310s, e hōʻike ana i ke kūpaʻa maikaʻi loa i ka oxidation a me ka corrosion.Hāʻawi kona kiʻekiʻe chromium a me ka nickel i kona ikaika kolo maikaʻi, e ʻae iā ia e hana i nā wela kiʻekiʻe me ka liʻiliʻi o ka deformation.Eia kekahi, hōʻike ʻo ia i ka pale wela kiʻekiʻe maikaʻi.
309s He kila kila kila
ʻO ka helu kūpono o 309S ma Kina ʻo 06Cr23Ni13.Ma US ua ʻike ʻia ʻo ia ʻo S30908 a hoʻokō i nā kūlana AISI a me ASTM.Hoʻopili pū ia me JIS G4305 maʻamau su a me ʻEulopa 1.4833.
ʻO 309S he kila kila ʻole-machining a me ka sulfur-free.Hoʻohana maʻamau ia i nā noi e koi ana i kahi ʻoki manuahi a me kahi hoʻopau maʻemaʻe.Ke hoʻohālikelike ʻia me 309 stainless steel, 309S ka haʻahaʻa haʻahaʻa o ke kalapona, kūpono ia no nā noi wili.
ʻO ka haʻahaʻa kalapona e hoʻemi i ka ua o nā carbide i loko o ka wahi wela kokoke i ka weld.Eia nō naʻe, ma lalo o kekahi mau kūlana, e like me ka weld erosion, aia kahi hiki ke hoʻoheheʻe intergranular i ke kila kila ma muli o ka ua carbide.
310S / 309S Kūikawā
310S :
1) maikaʻi oxidation kū'ē;
2) E hoʻohana i kahi ākea ākea (ma lalo o 1000 ℃);
3) Nonmagnetic solid solution state;
4) Kiʻekiʻe wela kiʻekiʻe ikaika;
5) maikaʻi weldability.
309S :
Hiki i ka mea ke kū i nā pōʻai hoʻomehana he nui a hiki i 980 ° C.Loaʻa iā ia ka ikaika kiʻekiʻe a me ka pale ʻana i ka oxidation, a he hana maikaʻi hoʻi i ka ʻāina carburizing kiʻekiʻe.

He mea koʻikoʻi ka 310S stainless steel i ka aerospace, kemika a me nā ʻoihana ʻē aʻe, a hoʻohana nui ʻia i nā wahi wela kiʻekiʻe.ʻO kekahi o kāna mau noi koʻikoʻi e pili ana i nā paipu exhaust, tubing, nā kapuahi hoʻomaʻamaʻa wela, nā mea hoʻololi wela, nā incinerators a me nā ʻāpana pili wela kiʻekiʻe.Ma keʻano kikoʻī, hoʻohana ʻia ʻo 310S stainless steel i nā ʻōnaehana hoʻopau o nā kaʻa, mokulele, a me nā mea hana ʻoihana ma muli o kona kūpaʻa wela kiʻekiʻe.Hoʻohana ʻia ia i loko o nā umu hoʻomaʻamaʻa wela e kōkua i ke kūkulu ʻana i nā mea hoʻomehana a me nā paipu kukui.Hoʻohui ʻia, hoʻohana ʻia ʻo 310S i ka hana ʻana i nā mea hoʻololi wela i hoʻolālā ʻia e kū i nā wahi corrosive a me nā kinoea wela a i ʻole nā wai.
