ʻO 321 he titanium stabilized chromium-nickel austenitic stainless steel me ka ikaika maikaʻi a me ke kūpaʻa maikaʻi maikaʻi loa, e like me ka mea i hoʻolako ʻia i ke kūlana annealed me ka paʻakikī brinell maʻamau o 175. Hōʻike ʻia e ke kūpaʻa corrosion kiʻekiʻe i nā kaiapuni corrosive ākea e hōʻike ana i ke kūpaʻa maikaʻi loa i ka hapa nui o ka oxidizing. nā meaʻai, nā meaʻai maʻamau, nā mea hoʻoheheʻe sterilizing, nā mea hoʻoheheʻe, ka nui o nā kemika organik a me nā ʻano kemika inorganic like ʻole, a me nā kinoea ʻaila wela, nā kinoea puhi mahu, nitric acid, a ma kahi liʻiliʻi o ka sulfuric acid.Hōʻike ia i ke kūpaʻa oxidation maikaʻi ma nā mahana kiʻekiʻe he kūʻē maikaʻi loa i ka corrosion intergranular a loaʻa ka weldability maikaʻi loa.ʻAʻole hiki ke hoʻopaʻakikī ʻia ʻo 321 e ka mālama wela, akā hiki ke hoʻonui nui ʻia ka ikaika a me ka paʻakikī e ka hana anu, me ka hoʻemi ʻana o ka ductility.
Hoʻohana nui ʻia no nā noi kahi o ka hoʻohui ʻana o ka titanium a me kāna hopena hoʻopaʻa ʻana ma ke ʻano he carbide forming element e hiki ai ke welded a/a i hoʻohana ʻia i loko o ka carbide precipitation range 430oC – 870oC me ka loaʻa ʻole o ka pōʻino intergranular.ʻO kēia mau mea e pili ana i ka Hoʻoponopono Meaʻai, Lako Waiwai, Chemical, Petrochemical, Transport a me nā ʻoihana pili.
ʻAʻole magnetic i ke kūlana annealed, akā hiki ke lilo i ka magnetic ma hope o ka hana anu nui.
Pono ka Annealing e hoʻoponopono inā pono.
NB Loaʻa ka pale corrosion maikaʻi loa ma ke kūlana annealed.
