Akā naʻe,, 1.4550 he nui loa pale aku i ke kaumaha o ka corrosion cracking i chrloside-waiwai nā wahi ma muli o ka hoʻohui o nihibium,
Ke kūpono nei i nā noi kiʻekiʻe i loko Ke wai wai Oole nā lāʻau kanu lāʻau. - ʻO ka hana kiʻekiʻe kiʻekiʻe: Hana maikaʻi nā papaʻelua i nā mahana kiʻekiʻe,
aka, 1.4550 Hāʻawi i ka hana maikaʻi aku i ka wā i hōʻikeʻia ai nā kiʻekiʻe kiʻekiʻe kiʻekiʻe i ka 400° C i 900 ° C Nā haʻona,
heaha 316 kūpono no Ke hoʻomau nei i ke kiʻekiʻe kiʻekiʻe ka hōʻikeʻana a hiki i 800° C. - Kālā: 1.4550 ʻoi aku ka nui o nā kumukūʻai ma muli o kāna Hōʻike Niobium a me ka hana kiʻekiʻe kiʻekiʻe,
heaha 316 he koho koho-kūpono no nāʻoihana e koi ana Ke kū'ē neiʻo Marine-Sade Corrosiotion.
1.4550 vsa 321 Kila kohu ʻole
321 Kila kohu ʻole he mea'ē aʻe kekahi Austetetitic kila kohu ʻole, e like me 304, Akā me ka hoʻohui o Titanium e hoʻokūpaʻa i kaʻikepili o ka carbon a pale aku intergranur corrosior.
Akā naʻe,, 1.4550 hāʻawi i nā pōmaikaʻi nui:
- Ke kū'ē neiʻo Corrosionion: 321 Kila kohu ʻole ua kū'ē i ke kū'ē intergranur corrosior a hana maikaʻi i loko ka mahana kiʻekiʻe nā wahi.
Akā naʻe,, 1.4550 hana maikaʻi i nā noi me ka hoʻohilahilaʻana, nui loa ma nā wahi nā mea hoʻohālikelike.
KAHUIA, 1.4550 oi aku ke kūleʻa nei i ke kaumaha o ke kalaʻana i nā wahi kiʻekiʻe-chloride. - ʻO ke kūpono kūpono: 321 ua hoʻolālāʻia no nā noi kiʻekiʻe kiʻekiʻe (a i 900° C), Ma kahi e hoʻokūkū aiʻo Titanium i ka waiwai.
Oiai 1.4550 hiki nō hoʻi i ke kūpaʻa mahana kiʻekiʻe, Uaʻoi aku ka maikaʻi o ka hana ma Hoʻopili i keʻano match cycling. - Kūpono no nā kūlana harsh: 1.4550 kūpono no nā noi i kahi Ke Kauka Kauka he mea maʻamau,
e like me nā wahi hau, nā mea hana wela, a nā mea hana loiloi,
heaha 321 hoʻohana pinepineʻia no Kōkua a nā'āpana'āpana kiʻekiʻe kahi o nā maka ʻO ka hoʻomehana lōʻihi Me kaʻole o ke kāhikoʻana.
8. Nā manaʻo noʻonoʻo a me ke kūpaʻa
E like me kahi mea hoihoi hou, 1.4550 Kila kohu ʻole Hāʻawiʻia i ka hana maʻamau.
Ua hoʻohana nuiʻia ia ʻOihana Hana'Eleʻo Uā nā hale hakakala a Ke kālepaʻana,
Ma kahi o ka hoʻemiʻana o ka hōʻemi a me ka recyclability he nui nā manaʻo nui. 1.4550 E pili ana i nā kūlana honua, hōʻoia e hoʻokō me nā lula e like me Roohs a Iso 9001.
9. Hopena
I ka hopena, 1.4550 Kila kohu ʻole he mea kiʻekiʻe loa e hāʻawi i nā mea i hāʻawiʻia Ke kū'ē neiʻo Corrosionion, ikaika, a ʻO ke kūpaʻa wela,
Ke kūpono nei ia no nā noi ma waena o nāʻano koi likeʻole.
Inā i hoʻohanaʻia ma ʻO nā wahi kai moana, Ke kālepaʻana, Oole Nā Hoʻohana lapaʻau, 1.4550 e hōʻoiaʻiʻo i ka hana kūpono a me ka lōʻihi lōʻihi.
Inā makemakeʻoe i nā hopena kila kila e hāʻawi i ka hana maikaʻi loa i ka hana kiʻekiʻe ma keʻano kiʻekiʻe,
ka mahana kiʻekiʻe, a me nā wahi kūpono, 1.4550 Kila kohu ʻole he koho kūpono kūpono.
ʻO nā waiwai nui a me nā mea i hanaʻia he mea nui no nā mea hana pono no nā mea hana a me nāʻenehana e koi ana i ka maikaʻi a me ka lōʻihi.
Ināʻoe eʻimi nei i nā huahana kila kila kiʻekiʻe kiʻekiʻe, ʻO ke kohoʻana i ka deze ka hoʻoholo kūpono loa no kāu mau hana hana.
