1. Hōʻikeʻike
Ma waena o nā helu he nui o ke kila kila i loaʻa i kēia lā, 440C kila kila Noho ʻo ia i kahi kūlana kūʻokoʻa e like me kekahi o nā kila kulika paʻakikī a paʻa loa i hiki ke hana ʻia ma o ka mālama wela maʻamau..
ʻO ka hui pū ʻana i ka ʻike kalapona kiʻekiʻe me ka hoʻohui chromium nui, 440Hāʻawi ʻo C i kahi kaulike kūʻokoʻa o ka paʻakikī, ikaika, kū ponoʻole, a me ke kū'ēʻana, lilo ia i mea makemake nui no nā noi ʻenekinia hana kiʻekiʻe.
Hoʻokumu mua ʻia no ka hoʻokō ʻana i ke koi ulu ʻana no nā kila hoʻopaʻa ʻana i ka corrosion-resistant a me nā ʻāpana mechanical precision, 440Ua ulu ʻo C i kekahi o nā kila kila martensitic kaulana loa.
Hoʻohana nui ʻia ia i nā ʻoihana kahi e kū ai i ka abrasion, ʻolokaʻi pili luhi, a ʻoi aku ka koʻikoʻi o ka hoʻohana ʻana i ka ʻili ma mua o ka pale ʻana i ka corrosion.
I kēia mau lā, ʻO nā mea i hana ʻia mai ka 440C hiki ke loaʻa i nā lako aerospace, nā mea hana lāʻau lapaʻau, nā pahu hana ʻoihana, Nā Kūlana Pali, Nā moa moa, Nā'Upō, mea ana ana, ʻO nā mīkini hoʻololi meaʻai, a me nā ʻōnaehana mechanical ʻē aʻe he nui.
2. He aha ka 440C Stainless Steel?
440C kila kohu ʻole he kila kila martensitic kiʻekiʻe kaulana no kona oolea okoa, E kāʻei i ke kū'ē, a me ka hiki ke mālama i nā ʻoki ʻoki a me nā ana kikoʻī ma lalo o nā kūlana lawelawe koi.
No ka 440 pūʻulu kila kila, e komo pū ana me 440A a me 440B, akā ʻo 440C ka mea kiʻekiʻe loa o ke kalapona, e ʻae ana e hoʻokō i ka paʻakikī loa ma hope o ka mālama ʻana i ka wela.
ʻAʻole like me nā mea kila kila ferritic a i ʻole austenitic, Loaʻa i nā kila kila martensitic ko lākou ikaika kiʻekiʻe ma o ka mālama ʻana i ka wela.
Ma ka hoʻomehana ʻana i ka mea i loko o ka ʻāina austenitic a me ka hoʻomaha wikiwiki ʻana, ua hoʻololi ke ʻano aniani i martensite—he supersaturated, ʻO ka māhele tetragonal e pili ana i ke kino i hōʻike ʻia e ka paʻakikī kiʻekiʻe a me ka ikaika.
Hoʻopaneʻe ka hoʻohālikelike ʻana i ke kaulike ma waena o ka paʻakikī, paʻakikī, a me ke kūpaʻa kiʻekiʻe.
ʻO ka hui kūʻokoʻa o ka martensitic matrix a me nā chromium carbide i hoʻopuehu maikaʻi ʻia e hiki ai iā 440C ke hōʻike.:
- ʻO ka paʻakikī ma hope o ka mālama wela

- Loaʻa maikaʻi maikaʻi
- Ke kū'ēʻana i ka paleʻana
- ʻOi loa ka polishability
- ʻO ka maikaʻi o ka hoʻopau ʻana i ka ʻili kiʻekiʻe
No keia mau ano, 440Ua ʻike nui ʻia ʻo C ma ke ʻano o kekahi o nā mea kila kila kila o ka ʻoihana a koho pinepine ʻia no nā ʻāpana mechanical pololei e hana ana ma lalo o nā kūlana ʻaʻahu koʻikoʻi..

10. Nā noi o 440C Kuhili ʻole
Mahalo i kona ʻano paʻakikī, E kāʻei i ke kū'ē, kū ponoʻole, a me ke kū'ēʻana, 440Hoʻohana ʻia ʻo C stainless steel ma kahi ākea o nā ʻoihana kahi i pololei, durability, a he mea nui ke ola lawelawe lōʻihi.
Piʻi pololei
440Ua ʻike nui ʻia ke kila kila C ma ke ʻano he mea kikoʻī no nā bearings kinipōpō.
Hoʻokomoʻia nā noi:
- ʻAerospace bearings
- Piʻi lāʻau lapaʻau
- Mīkini hana ʻai
- ʻO nā spundles kiʻekiʻe-wikiwiki
- Nā mea kani pololei
Nā'āpana Valve
I nā ʻōnaehana hoʻomalu wai ʻoihana, 440Hoʻohana mau ʻia ke kila kila C no:
- Nā kinipōpō pōlele
- Noho kiwi
- ʻO nā lāʻau pāpaʻi
- E nānā i nā ʻāpana valve
ʻO nā mea hana olakino a me nā mea lapaʻau
ʻO ka hiki o ka alloy ke hoʻokō i kahi ʻoi ʻoi, hui pū ʻia me ke kūpaʻa corrosion maikaʻi a me ka polishability maikaʻi loa, hana ia i kūpono no:
- ʻoki ʻokiʻoki
- ʻO nā pūlima
- ʻOki iwi
- Nā Huakua Delika
- Nā mea kani orthopedic
ʻO nā lāʻau lapaʻau e like me ka electropolishing a me ka passivation e hoʻonui hou i ka maʻemaʻe a me ka pale ʻana i ka corrosion.
Pahi pahi a me na mea hana oki
ʻO kekahi o nā noi kaulana loa o 440C stainless steel aia i nā pahi kiʻekiʻe.
Hāʻawi ka alloy:
- Paʻa lihi maikaʻi
- ʻO paʻakikī paʻakikī
- ʻO ke kū'ēʻana o ka corrossion maikaʻi
- Hiki maikaʻi ka poli
Hoʻohana mau ʻia no ka ʻimi ʻana i nā pahi, pahi luʻu, nā lau ʻoihana, a me nā mea ʻoki kīhini premium.
Hold Hana
Hoʻohana nui ʻia ke kila kila 440C i kālai ʻia i loko o nā pahu i hoʻopaʻa ʻia a me nā mea hana pololei ma muli o kona kūpaʻa ʻana., Ke kū'ē neiʻo Corrosionion, a me ka hiki ke mālama i ka hopena maikaʻi loa.
Pum a me Mechanical Sila Mea
Nā ʻāpana e like me nā shafts, moe 'ana, apo sila, a e hoʻohana i nā papa e pōmaikaʻi mai ka 440C stainless steel's resistance to abrasion a me ka hoʻohaʻahaʻa haʻahaʻa, kūpono ia no nā ʻōnaehana pauma ʻoihana.
Nā lako hana meaʻai
Ma nā wahi hana meaʻai, 440Hoʻohana ʻia ke kila kila C no:
- Nāʻokiʻoki
- ʻO nā mea hana ʻoki
- ʻO nā wili pololei
- E hoʻohana i nā ʻāpana
Ke ana ana i nā mea hana
Ma muli o kona kūpaʻa dimensional a me ka paʻakikī, 440Ua koho pinepine ʻia ke kila kila C no:
- Nā poloka ana
- Ke ana ana i na probes
- Nā milo pololei
- ʻO nā mea hoʻoponopono hoʻoponopono
Nā mīkini mīkini
Nui nā noi ʻoihana maʻamau e hilinaʻi i ka 440C stainless steel no nā mea i hoʻopaʻa ʻia i ka friction mau a me ka lole, e like me:
- Kāmeʻa hahai
- Nā alakaʻi kaʻa
- ʻōnaehana neʻe laina
- E ʻaʻahu i nā pā
- Bussings
- Nāʻuala maikaʻi

Hiki iā 440C ke kila kila?
440Loaʻa iā C ka chromium lawa no ka hana ʻana i kahi ʻāpana ʻokikene paʻa pale, hāʻawi iā ia i ka pale ʻana i ka corrosion maikaʻi ma lalo o nā kūlana maʻamau a me ka wai maʻemaʻe.
Akā naʻe,, ʻo ia ʻaʻole pau ka ʻeleʻele.
I loko o ka chloride-waiwai, Marine, a i ʻole nā kaiapuni ʻakika loa, hiki ke ʻino ʻia ke kiʻiʻoniʻoni passive a i ʻole ka mālama pono ʻana.
ʻOi aku ka 440C ma mua o 316 kila kohu ʻole?
Hoʻohana ʻia kēia mau papa ʻelua i nā kumu like ʻole. 440C kila kila ua hoʻolālā ʻia no ka paʻakikī a me ke kūpaʻa ʻana, hana ia mea kūpono no nā bearings, ʻokiʻana i nā hana hana, a me nā ʻāpana mechanical precision.
316 ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion - ʻoi aku ka maikaʻi ma ke kai a me nā kaiaola kemika - akā ʻaʻole hiki ke mālama ʻia i ka wela e loaʻa ai ka paʻakikī like..
ʻO ka koho ʻoi aku ka maikaʻi ma muli o ka hana mechanical a i ʻole ke kūpaʻa ʻana i ka corrosion ka mea hoʻolālā mua.
Hiki iā 440C ke kila kila?
Hiki i ka welding 440C akā ʻaʻole i ʻōlelo ʻia no ka mea ʻoi aku ka nui o ke kalapona kiʻekiʻe e hoʻonui i ka pilikia o ka haki ʻana a me ka distortion..
Inā ʻaʻole hiki ke pale ʻia ka wili, hoʻomāhana mua, mea hoopiha kupono, kāohiʻia hōʻoluʻolu, a me ka mālama ʻana i ka wela ma hope o ka weld e hoʻihoʻi hou i nā waiwai mechanical a hōʻemi i nā koʻikoʻi koena.
Hiki iā 440C ke aniani i poni ʻia?
ʻAe. ʻO kekahi o nā pōmaikaʻi koʻikoʻi o 440C ʻo ia ka maikaʻi o ka polishability.
Ma o ka wili pololei, hoʻopololei mechanical, a me ka electrophishinging, hiki ke hoʻokō i kahi ultra-smooth, hoʻopau ʻili e like me ke aniani.
ʻO kēia ka mea kūpono loa ia no nā mea hana ʻoki, nā poʻi pololei, nā mea hoʻopaʻa ʻike, a me na pahi pahi.
