ʻO 321 Stainless Steel he kila kuhiliʻole austenitic i hoʻopaʻa ʻia me ka titanium.Loaʻa i ka 321 ka chromium a me ka nickel a me ka titanium, hāʻawi i ka hoʻomaikaʻi ʻana i ke kūpaʻa inter-granular corrosion.321 ma non-magnetic w/similar corrosion resistance i ke ʻano 304. Hoʻohana ʻia kēia mea no nā mea welded ʻaʻole hiki ke annealed.Eia kekahi, hoʻohana ʻia ia no nā mea hana i hana ʻia ma waena o 800 a me 1500 ° F.
Loaʻa ka 321 ma ka pahu poepoe, ka pā, ka paipu, ka pepa, ka paipu, ka wili a me ka paipu.No nā pono kila kila 321, e kelepona iā Michlin Metals.No ka ʻike hou aku e pili ana i kēia a me nā Austenitic Stainless Steels e nānā i kahi wikiō ma kēlā kumuhana ma lalo nei.
321 kuhiliʻole kila seamless paipu kila (GB3087-1999) he kiʻekiʻe kalapona structural kila wela-wili a me anu (rolled) seamless paipu kila, i hoʻohana 'ia no ka hana superheated mahu paipu, paila wai paipu o na like haʻahaʻa a me ka medium pressure boilers. a me na paipu mahu wela loa, na paipu uwahi nui, na paipu uwahi liilii, a me na paipu pilaka pio o na paila locomotive.
321 kuhiliʻole kila paipu: Nui i hoʻohana 'ia i loko o ka hana o kiʻekiʻe puʻe a ma luna o ke kaomi mahu paila paipu, etc. Me ka kiʻekiʻe kalapona structural kila, ke kila kila a me kuhiliʻole wela kila seamless kila paipu, ka paila paila e ka pāʻina ma lalo kiʻekiʻe wela a me kiʻekiʻe puʻe paipu a me ka hana i loko o ke kiʻekiʻe wela flue kinoea a me ka mahu e hana ma lalo o ka hana o ka oxidation a me ka corrosion, no laila, i ka paipu kila me ke kiʻekiʻe rupture ikaika, kiʻekiʻe oxidation kū'ē, A he maikai hui paʻa, hydraulic prop paipu.
Hāʻawi ʻia nā paipu kila kila 321 i ke kūlana mālama wela.Eia kekahi, pono pū ka microstructure, ka nui o ka palaoa a me ka decarburization layer o nā paipu kila i hoʻopau ʻia.ʻO nā paipu kila maʻemaʻe no ka hoʻoheheʻe honua a me ka hoʻomalu ʻana i ka ʻaila ʻaila;No ka ʻimi ʻana i ka hale pōhaku lalo, ka wai lepo, ka aila, ke kinoea maoli a me nā kumu waiwai mineral, ka hoʻohana ʻana i nā Wells drilling.
