Kaʻina hana:
ʻO nā mea maka (C, Fe, Ni, Mn, Cr a me Cu), hoʻoheheʻe ʻia i loko o nā ingots e nā mea nani AOD, ʻōwili wela i ka ʻili ʻeleʻele, pickling i loko o ka wai waikawa, poni ʻia e ka mīkini a ʻokiʻoki i ʻāpana.
Nā Kūlana:
ASTM A276, A484, A564, A581, A582, EN 10272, JIS4303, JIS G 431, JIS G 4311 a me JIS G 4318

Nā hiʻohiʻona:
ʻO ka hiʻohiʻona maikaʻi o ka ʻālohilohi o nā huahana i ʻōwili ʻia
ʻO ka ikaika wela kiʻekiʻe maikaʻi
ʻO ka hana paʻakikī maikaʻi (ma hope o ka hoʻoili ʻana i ka magnetic palupalu)
Haʻina mokuʻāina non-magnetic
He kūpono no ka hale kūkulu hale, kūkulu hale a me nā mea hana ʻē aʻe
Nā noi:
kahua kūkulu, ʻoihana kūkulu moku
Nā mea hoʻonani a me ka papa hoʻolaha hoʻolaha waho
Kaʻa kaʻa i loko a me waho i ka ʻeke a me ka hale a me nā pūnāwai
Nā lima lima, electroplating a electrolyzing pendants a me nā meaʻai
Corrosion- a me ka abrasion-free e hoʻokō i nā koi kikoʻī o nā mīkini like ʻole a me nā māla lako Me ka ʻike ākea a me ka ʻike,

ʻIke kumu
ʻO 321 ka pahu kila kila, i ʻike ʻia ʻo UNS S32100 a me ka Papa 321, ʻo ia ka mea nui o 17% a 19% chromium, 12% nickel, .25% a 1% silicon, 2% manganese kiʻekiʻe, nā ʻāpana o ka phosphorus a me ka sulfur, 5 x (c + n) .70% titanium, me ke koena he hao.E pili ana i ka pale ʻana i ka corrosion, ua like ka 321 me ka Papa 304 i ke kūlana annealed a ʻoi aku ka maikaʻi inā pili ka noi i ka lawelawe ma ka pae 797° a 1652° F.Hoʻohui ka papa 321 i ka ikaika kiʻekiʻe, ke kū'ē i ka scaling a me ka paʻa o ka pae me ke kū'ē i ka ʻino wai aʻe.
Palapala noi
ʻO ka 321 stainless round steel bar he mea maʻalahi e ʻike i kāna noi ma nā ʻano ʻoihana.Hoʻohana maʻamau ia i ka ʻoihana hana, ʻoihana kūkulu hale, a hiki i ka ʻoihana kaʻa.He kūpono kēia ʻano pā no ka hoʻohana ʻana i nā hale, nā alahaka, a me nā hale ʻē aʻe ma muli o kona ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion.
He mea waiwai kēia i ka ʻoihana hana e hana i nā paipu, nā paila, nā pahu, a me nā mea mīkini ʻē aʻe.Hoʻohana ʻia ia i ka ʻoihana kaʻa e hana i nā kino kaʻa a me nā ʻāpana kaʻa ma o ka hoʻopili ʻana iā lākou me ka alumini a i ʻole nā metala ʻē aʻe.
Hiki iā ia ke koʻokoʻo a i ʻole ka paipu me kahi ʻāpana keʻa pōʻai, i hana ʻia e ka ʻōwili a i ʻole extrusion.Kaulana ʻia ka pā i ka hana ʻana a me nā noi ʻenekinia e hana i nā ʻano hana e like me nā kahawai, nā kihi, nā I-beams, a me nā H-beams.
Eia kekahi, hiki ke ʻoki ʻia i nā ʻano nui a me nā ʻano e kūpono i nā koi o ka papahana.Hoʻohana maʻamau ia ma ke ʻano he mea hoʻoikaika no ka ʻuala a i ʻole nā mea kūkulu hale ʻē aʻe.
