Mai ka haku mele ʻana a hiki i ke ʻano, pili nā ʻano kumu i nā ʻano o nā huahana stainless steel.ʻO kekahi o nā mea nui e noʻonoʻo ai ʻo ia ka pae o ke kila e hoʻohana ai.E hoʻoholo kēia i kahi ʻano o nā hiʻohiʻona a, i ka hopena, ʻo ke kumukūʻai a me ke ola o kāu mau huahana kila kila.
No laila pehea ʻoe e ʻike ai i kahi e hoʻomaka ai?
ʻOiai ʻokoʻa kēlā me kēia noi, hōʻike kēia mau nīnau 7 i nā noʻonoʻo koʻikoʻi e kōkua iā ʻoe e hōʻemi i kāu mau koho a ʻike i nā māka i kūpono i kāu pono a i ʻole kāu noi.
1. He aha ke ʻano o ke kūʻē ʻana e pono ai koʻu hao?
Ke noʻonoʻo ʻoe i ke kila kila, ʻo nā mea mua i hiki i ka naʻau ke kūʻē i nā waikawa a me nā chlorides - e like me nā mea i loaʻa i nā noi ʻoihana a i ʻole nā kaiapuni kai.Eia nō naʻe, ʻo ke kūpaʻa wela ka mea nui e noʻonoʻo ai.
Inā makemake ʻoe i ka pale ʻana i ka corrosion, makemake ʻoe e pale i nā kila ferritic a me martensitic.ʻO nā māka kila kila kila maikaʻi loa no nā kaiapuni corrosive e loaʻa nā austenitic a i ʻole duplex alloys e like me nā māka 304, 304L, 316, 316L, 2205, a me 904L.
No nā kaiapuni wela kiʻekiʻe, ʻoi aku ka maikaʻi o nā māka austenitic.ʻO ka loaʻa ʻana o kahi papa me ka chromium kiʻekiʻe, ka silikoni, ka nitrogen, a me nā mea ʻeleʻele koʻikoʻi e hoʻololi hou i ka hiki o ke kila ke kū i nā wela kiʻekiʻe.ʻO nā māka maʻamau no nā kaiapuni wela kiʻekiʻe ka 310, S30815, a me 446.
He mea kūpono hoʻi nā māka kila Austenitic no nā wahi haʻahaʻa haʻahaʻa a cryogenic paha.No ke kū'ē hou aku, hiki iā ʻoe ke nānā i ke kalapona haʻahaʻa a i ʻole nā māka hau hau kiʻekiʻe.ʻO nā māka maʻamau no nā kaiapuni haʻahaʻa haʻahaʻa ʻo 304, 304LN, 310, 316, a me 904L.
2. Pono anei ko'u hao?
ʻO ke kila me ka maikaʻi ʻole o ke ʻano e lilo i mea palupalu inā hana nui a hāʻawi i ka hana haʻahaʻa.I ka hapanui o nā hihia, ʻaʻole ʻōlelo ʻia nā kila martensitic.Eia kekahi, ʻaʻole paʻa ke kila me ke ʻano haʻahaʻa i kona ʻano ke koi ʻia ka hana paʻakikī a paʻakikī paha.
Ke koho ʻana i kahi papa kila, makemake ʻoe e noʻonoʻo i ke ʻano āu e makemake ai e hoʻouna ʻia.Inā makemake ʻoe i nā koʻokoʻo, nā pāpaʻi, nā kī a i ʻole nā lau e kaupalena i kāu mau koho.No ka laʻana, kūʻai pinepine ʻia nā kila ferritic i nā ʻāpana, kūʻai pinepine ʻia nā kila martensitic i nā kaola a i ʻole nā papa, a loaʻa nā kila austentic i nā ʻano ākea loa.ʻO nā māka kila ʻē aʻe i loaʻa i nā ʻano like ʻole me 304, 316, 430, 2205, a me 3CR12.
3. E koi mai anei ko'u hao i ka mīkini?
ʻAʻole pilikia ka mīkini maʻamau.Eia naʻe, hiki i ka hana paʻakikī ke hana i nā hopena i manaʻo ʻole ʻia.Hiki i ka hoʻohui ʻana i ka sulfur ke hoʻomaikaʻi i ka machinability akā e hōʻemi i ka formability, weldability a me ka pale ʻana i ka corrosion.
Hana kēia i ka loaʻa ʻana o ke kaulike ma waena o ka machinability a me ka pale ʻana i ka corrosion i mea noʻonoʻo nui no ka hapa nui o nā kaʻina hana hana kila stainless multistage.Ma muli o kāu mau pono, hāʻawi nā māka 303, 416, 430, a me 3CR12 i kahi kaulike maikaʻi e hōʻemi ai i nā koho.
4. Pono anei au e wili i ko'u hao hao?
ʻO ka wiliwili ʻana i ke kila kila hiki ke alakaʻi i ka pilikia—e like me ka pohā wela, ka pohā ʻino o ke koʻikoʻi, a me ka corrosion intergranular—ma muli o ke ʻano o ke kila i hoʻohana ʻia.Inā hoʻolālā ʻoe e wili i kāu kila kila, maikaʻi loa nā alloys austenitic.
Hiki i nā māka kalapona haʻahaʻa ke kōkua hou aku me ka weldability ʻoiai nā mea hoʻohui, e like me ka niobium, hiki ke hoʻopaʻa i nā alloys e pale i nā pilikia corrosion.ʻO nā māka kaulana o ke kila kila no ka wiliwili ʻana me 304L, 316, 347, 430, 439 a me 3CR12.
5. Pono anei ka Lapaau Wela?
Inā makemake kāu noi i ka mālama wela, pono ʻoe e noʻonoʻo i ka pane ʻana o nā māka like ʻole o ke kila.He ʻokoʻa loa nā hiʻohiʻona hope o kekahi mau kila ma mua a ma hope o ka mālama ʻana i ka wela.
I ka hapanui o nā hihia, hāʻawi nā kila martensitic a me ka ua, e like me 440C a i ʻole 17-4 PH, i ka hana maikaʻi loa ke mālama ʻia ka wela.ʻAʻole paʻakikī ka nui o nā austenitic a me ka ferritic stainless steel i ka wā e mālama ʻia ai ka wela a no laila ʻaʻole ia he koho kūpono.
6. He aha ka ikaika o ka hao i kūpono no kaʻu noi?
ʻO ka ikaika o ke kila he mea nui e noʻonoʻo ai e hoʻonui i ka palekana.Eia nō naʻe, hiki i ka overcompensating ke alakaʻi i ke kumu kūʻai pono ʻole, ke kaumaha, a me nā mea ʻino ʻē aʻe.Hoʻonohonoho ʻia nā hiʻohiʻona ikaika e ka ʻohana kila me nā ʻano like ʻole i loaʻa i nā papa like ʻole.
7. He aha ke kumu kūʻai mua a me ke kumu kūʻai o ke ola o kēia hao i loko o kaʻu kiʻi?
ʻO nā manaʻo mua a pau e pili ana i ka nīnau nui loa i ke koho ʻana i kahi papa kila kuhiliʻole - ke kumu kūʻai o ke ola.Hoʻohālikelike i nā māka kila kila i kāu kaiapuni i manaʻo ʻia, hoʻohana a me nā koi, hiki iā ʻoe ke hōʻoia i ka hana lōʻihi a me ka waiwai kūʻokoʻa.
E noʻonoʻo i ka hana ʻana o ke kila i ka manawa i manaʻo ʻia e hoʻohana ʻia a me nā kumukūʻai e pili ana i ka mālama ʻana a i ʻole ke pani ʻana ma mua o ka hoʻoholo ʻana.ʻO ka hoʻopaʻa ʻana i nā kumukūʻai ma mua e hiki ke hoʻonui i ka hoʻolilo ʻana i ke ola o kāu papahana, huahana, hale, a i ʻole nā noi ʻē aʻe.
Me ka heluna nui o nā māka kila kila a me nā ʻano i loaʻa, loaʻa kahi loea e kōkua i ka hōʻike ʻana i nā koho a me nā pitfalls he ala maikaʻi loa ia e hōʻoia i ka loaʻa ʻana o ka waiwai maikaʻi loa no ka hoʻopukapuka kila kila.Ma ke ʻano he alakaʻi alakaʻi o ke kila kila ma mua o 20 mau makahiki, e hoʻohana ʻo Jindalai Steel Group i kā mākou ʻike e kōkua i ke alakaʻi ʻana iā ʻoe ma ke kaʻina kūʻai.E nānā i kā mākou papa inoa nui o nā huahana stainless ma ka pūnaewele a i ʻole kelepona e kūkākūkā i kāu mau pono me kahi lālā o kā mākou hui.
