He Magnetic ke kila kila 17-4

I ke ao o nā mea kila kila, nīnau pinepine nā ʻenekinia a me nā mea hana,he 17-4 kila kila kila ka magneticHe mea nui loa kēia nīnau i ke koho ʻana i nā mea no nā noi e pili ana i nā kahua magnetic, nā mea hana pololei, a i ʻole nā ​​​​wahi kahi e hoʻopilikia ai nā waiwai magnetic i ka hana.

17-4 kila kila, ʻike ʻia hoʻi ʻoʻAISI630, he metala ikaika kiʻekiʻe, kūpaʻa i ka palaho i hoʻohana nui ʻia i nā ʻoihana aerospace, moana, kemika, a me ka ikehu. Ma kēia ʻatikala, e ʻimi mākou inā he magnetic ke kila kila 17-4, he aha ka mea e hoʻopilikia ai i kāna ʻano magnetic, a no ke aha he mea nui ka hoʻomaopopo ʻana i kona mau waiwai magnetic no nā noi ʻoihana.

ʻIkepili o ke kila kila 17-4

ʻO ke kila kila 17-4 hekila kila martensitic paʻakikī-wai. Loaʻa kona inoa mai kona haku mele ʻana: kokoke17% chromium a me 4% nickel, me nā liʻiliʻi o ke keleawe, manganese, a me ka niobium. He waiwai nui ia no konaikaika mīkini maikaʻi loa, kūpaʻa maikaʻi i ka pala, a me ka hiki ke hoʻopaʻakikī ʻia ma o ka mālama wela ʻana.

Hoʻolako pinepine ʻia kēia kila i kona kūlana i mālama ʻia me ka hoʻonā (Kūlana A), akā hiki ke mālama ʻia i ka wela i nā ʻano ʻano like ʻole e like me H900, H1025, a me H1150, ma muli o ka ikaika a me ke kūpaʻa i makemake ʻia.

At sakysteel, hoʻolako mākou17-4 kila kilai nā kaola poepoe, nā papa, nā pepa, a me nā ʻaoʻao maʻamau, e hoʻokō ana i nā kūlana honua a me nā koi kūlana koʻikoʻi.

He Magnetic anei ke kila kila 17-4?

ʻAe, 17-4 kila kilahe makenekaʻO kēia ʻano hana magnetic ma muli nui o kānaʻano kristal martensitic, ka mea i hana ʻia i ka wā o ke kaʻina hana wela. ʻAʻole e like me nā kila kila austenitic e like me 304 a i ʻole 316, ʻaʻole ia he magnetic ma muli o ko lākou ʻano cubic face-centered (FCC), loaʻa iā 17-4 kahicubic i kikowaena ʻia e ke kino (BCC) a i ʻole ka hoʻolālā martensitic, ka mea e hiki ai iā ia ke hōʻike i nā waiwai magnetic.

ʻO ke kekelē o ka magnetism i loko17-4 kila kilahiki ke ʻokoʻa ma muli o:

• Kūlana mālama wela(Kūlana A, H900, H1150, a pēlā aku.)

• Ka nui o ka hana anua i ʻole ka mīkini ʻana

• Ke koʻikoʻi koena i loko o ka mea

No ka hapa nui o nā kumu kūpono, ua manaʻo ʻia he kila kila 17-4 PHikaika ka makeneka, ʻoi aku hoʻi i ka hoʻohālikelike ʻia me nā ʻano kila kila ʻē aʻe.

Nā Waiwai Magnetic i nā Hana Wela like ʻole

Hiki ke loli iki ka pane magnetic o ke kila kila 17-4 ma muli o kona kūlana mālama wela:

• Kūlana A (Hoʻonā i mālama ʻia)Mākēneki iki

• Kūlana H900ʻOi aku ka ikaika o ka pane magnetic ma muli o ka hoʻonui ʻia o ka ʻike martensitic

• Kūlana H1150: Pane magnetic haʻahaʻa iki akā magnetic nō naʻe

Eia nō naʻe, ʻoiai i loko o ke kūlana i mālama ʻia me ka hopena,17-4 kila kilamālama i kahi ʻano magnetic. ʻO kēia ka mea e hana aiʻaʻole kūpono no nā noi e pono ai nā mea non-magnetic loa, e like me kekahi mau mea lapaʻau a i ʻole nā ​​​​wahi MRI.

Pehea e pili ai ka Magnetism i nā noi ʻoihana

ʻO ka ʻike ʻana he mea nui ka kila kila 17-4 no nā ʻoihana kahikūlike magneticmea nui. Eia kekahi laʻana:

• In aerospace a me ka pale kaua, pono e noʻonoʻo ʻia nā waiwai magnetic i ka pale uila a me nā hale lako.

• In hana ʻana, hiki i nā waiwai magnetic ke hoʻohana i nā lako hāpai a hoʻokaʻawale magnetic.

• In nā hale hana kemika, hiki i ka magnetism ke hoʻopilikia i ka hana inā hōʻike ʻia nā mea i nā kahua electromagnetic.

Inā koi kahi noi i ka ʻike magnetic a i ʻole ka hoʻokaʻawale magnetic, kūpono paha ke kila kila 17-4. Ma ka ʻaoʻao ʻē aʻe, no nā ʻāpana kokoke i nā mea uila koʻikoʻi a i ʻole kahi e pono ai ka hana non-magnetic,nā papa austenitice like me 304 a i ʻole 316 paha nā koho ʻē aʻe maikaʻi aʻe.

Hoʻohālikelike me nā Papa Kila Kila ʻē aʻe

ʻO ka hoʻomaopopo ʻana i ke ʻano o ka hoʻohālikelike ʻana o 17-4 me nā māka ʻē aʻe e kōkua i nā ʻenekinia e hana i nā hoʻoholo mea maikaʻi aʻe:

• 304/316 kila kilaʻAʻole magnetic i ke kūlana annealed; hiki ke lilo iki i magnetic i ka wā e hana anu ai

• 410 kila kila: Magnetic ma muli o kona ʻano martensitic; haʻahaʻa ke kūpaʻa ʻana i ka pala ma mua o 17-4

• 17-7 PH kila kilaNā ʻano magnetic like; ʻoi aku ka maikaʻi o ke ʻano akā ʻoi aku ka ikaika ma mua o 17-4

No laila, kūpono ka 17-4 PH i ka wā ʻeluaikaika a me ke kūpaʻa kūpono i ka palahonā mea e pono ai, mehana makeneka.

At sakysteel, kōkua mākou i nā mea kūʻai aku e koho i ke kūlana kila kila kūpono e pili ana i nā koi noi kikoʻī, me ka hoʻohālikelike magnetic a me nā waiwai mechanical.

Nā ʻAno Hoʻāʻo Magnetic

No ka hoʻoholo ʻana i nā waiwai magnetic o ke kila kila 17-4, hiki ke hoʻohana ʻia kekahi mau ʻano hoʻāʻo:

• Hoʻāʻo huki magnetKe hoʻohana nei i kahi magnet mau loa e nānā i ka huki ʻana

• Ana ʻana o ka permeability magnetic: Ke ana i ka nui o ka pane ʻana o ka mea i kahi kahua magnetic

• Ka hoʻāʻo ʻana o kēia au EddyʻIke i nā ʻokoʻa o ka conductivity a me ka magnetism

Hiki i kēia mau hoʻokolohua ke kōkua i ka ʻike ʻana i nā mea kūpono loa no nā noi koʻikoʻi.

Hōʻuluʻulu manaʻo

No ka pane pololei ʻana i ka nīnau:ʻAe, he makeneka ke kila kila 17-4, a ʻo kāna hana magnetic ka hopena o iaʻano martensitici hana ʻia i ka wā o ka mālama wela. ʻOiai ʻaʻole paha ia e kū i ka pala e like me nā kila kila austenitic, hāʻawi ʻo 17-4 i kahi kaulike kū hoʻokahi oikaika, paʻakikī, kūpaʻa i ka pala, a me ka magnetism, e lilo ana i mea waiwai nui ma nā ʻoihana like ʻole.

I ke koho ʻana i ke kila kila no kāu papahana, e noʻonoʻo inā he pono a he palena paha nā waiwai magnetic. Inā makemake ʻoe i kahi mea e hui pū aipane magnetic me ka hana mechanical kiʻekiʻe, he koho maikaʻi loa ke kila kila 17-4 PH.

No nā huahana kila kila 17-4 kiʻekiʻe, me nā kaola poepoe, nā pepa, a me nā ʻāpana maʻamau, hilinaʻisakysteel— kāu hoa hilinaʻi no nā hoʻonā kila kila pololei a me ke kākoʻo mea akamai.
