Hiki ke mālama ʻia ke kila kila?

ʻO ke kila kila kekahi o nā mea i hoʻohana nui ʻia ma ka honua, i ʻike ʻia no kona kūpaʻa ʻana i ka corrosion, ikaika, a me ke ʻano maʻemaʻe. Akā ʻo kahi nīnau maʻamau i nīnau pinepine ʻia ma nā pōʻai ʻenehana a me ka ʻenekinia:Hiki ke mālama ʻia ke kila kila?ʻO ka pane ʻae-akā pili ia i ke ʻano o ke kila kila a me nā hopena i makemake ʻia.

Ma kēia ʻatikala, ʻimi mākou i nā mea kila kila e hiki ke mālama ʻia i ka wela, nā ʻano hana wela like ʻole, a pehea e pili ai kēia i ka hana ma nā noi honua maoli.

Ka hoomaopopo ana i na ano kila kila

No ka hoʻomaopopo ʻana i nā hiki ke hoʻomaʻamaʻa wela, he mea nui e ʻike i nā ʻāpana nui o ke kila kila:

1. Austenitic Stainless Steel(e laʻa, 304, 316)
   ʻO kēia nā māka maʻamau, ʻike ʻia no ka pale ʻana i ka corrosion maikaʻi akāʻaʻole hiki ke hoʻopaʻakikī ʻia e ka mālama wela. Hiki ke hooikaika wale ia lakou e ka hana anu.

2. He kila kila ʻole Martensitic(e laʻa, 410, 420, 440C)
   ʻO kēia mau mākahiki ke mālama i ka welae hoʻokō i ka paʻakikī kiʻekiʻe a me ka ikaika, e like me nā kila kalapona.

3. ʻO Ferritic Stainless Steel(e laʻa, 430)
   ʻO nā ʻano Ferritic i kaupalena ʻia ka hardenability aʻaʻole hiki ke hoʻopaʻakikī nui ʻia e ka mālama wela. Hoʻohana pinepine ʻia lākou i nā ʻoki a me nā mea hana.

4. Duplex Steel Steel(e laʻa, 2205, S31803)
   ʻO kēia mau kila he microstructure hui ʻia o austenite a me ferrite. ʻOiai lākouhiki ke komo i ka solution annealing, ʻo lākouʻaʻole kūpono no ka paʻakikīma o nā ʻano hana lapaʻau maʻamau.

5. He kila kuhiliʻole ka paʻakikī o ka ua(e laʻa, 17-4PH / 630)
   Hiki ke mālama ʻia kēia mau mea i ka wela a hiki i nā pae ikaika kiʻekiʻe loa a hoʻohana mau ʻia i ka aerospace a me nā noi hoʻolālā kiʻekiʻe.

At sakysteel, Hāʻawi mākou i nā ʻāpana kila kuhili ʻole nui, me nā māka martensitic hiki ke mālama ʻia i ka wela a me ka paʻakikī o ka ua me ka palapala hōʻoia piha a me ka traceability.

Nā ʻano hana hoʻomaʻamaʻa wela no ke kila kila

ʻO ke kaʻina hana hoʻomaʻamaʻa wela no ke kila kila e pili ana i ka hoʻomehana ʻana a me nā pōʻai anuanu e hoʻololi i ka microstructure a me nā waiwai mechanical. Aia ma lalo iho nā kaʻina hana hoʻomaʻamaʻa wela maʻamau i hoʻohana ʻia no nā kila kuhili ʻokoʻa:

1. Hoʻopili

Ke kumu:Hoʻokuʻu i ke kaumaha o loko, hoʻomaʻamaʻa i ke kila, a hoʻomaikaʻi i ka ductility.
Nā papa kūpono:Austenitic, ferritic, duplex stainless steels.

ʻO ka Annealing ka hoʻomehana ʻana i ke kila i kahi mahana o 1900–2100°F (1040–1150°C) a laila hoʻolili koke iā ia, ma ka wai a i ʻole ka ea. Hoʻihoʻi kēia i ka pale ʻana i ka corrosion a maʻalahi ka hana ʻana a i ʻole ka mīkini.

2. Ka paakiki

Ke kumu:Hoʻonui i ka ikaika a me ke kūpaʻa ʻaʻahu.
Nā papa kūpono:Na kila kuhiliʻole Martensitic.

Pono ka paʻakikī e hoʻomehana i ka mea i kahi wela kiʻekiʻe (ma kahi o 1000-1100 ° C), a ma hope o ke kinai wikiwiki ʻana i ka ʻaila a i ʻole ka ea. ʻO kēia ka hopena i kahi ʻano paʻakikī akā palupalu, ka mea maʻamau e ukali ʻia e ka hoʻomaʻamaʻa e hoʻoponopono i ka paʻakikī a me ka paʻakikī.

3. Hoohuoi

Ke kumu:Hoʻemi i ka brittleness ma hope o ka paʻakikī.
Nā papa kūpono:Na kila kuhiliʻole Martensitic.

Ma hope o ka paʻakikī, hana ʻia ka hoʻomaʻamaʻa ʻana ma ka hoʻomaʻamaʻa ʻana i ke kila i kahi mahana haʻahaʻa (150–370 ° C), e hoʻemi iki i ka paʻakikī akā e hoʻomaikaʻi i ka paʻakikī a me ka hoʻohana.

4. Ka Paʻa ʻana o ka Ua (Aging)

Ke kumu:Loaʻa i ka ikaika kiʻekiʻe me ke kūpaʻa corrosion maikaʻi.
Nā papa kūpono:PH nā kila kila (e laʻa, 17-4PH).

ʻO kēia kaʻina hana e pili ana i ka lāʻau hoʻonā a ukali ʻia e ka ʻelemakule ma nā mahana haʻahaʻa (480–620°C). Hāʻawi ia i nā ʻāpana e hiki i nā pae ikaika loa me ka liʻiliʻi o ka distortion.

No ke aha e mālama ai ʻo Heat i ke kila kila?

Nui nā kumu e koho ai nā mea hana a me nā ʻenekinia no ka mālama wela ma ke kila kila:

• Hoʻonui Paʻakikīno ka ʻoki ʻana i nā mea paahana, nā ʻāpana, a me nā ʻāpana pale pale

• Hoʻomaikaʻi ʻia ka ikaikano nā mea hana i loko o ka aerospace a me ka automotive

• Hoʻomaha pilikiama hope o ka wiliwili a i ʻole ka hana anu

• Hoʻomaʻamaʻa Microstructuree hoʻihoʻi i ka pale ʻana i ka corrosion a hoʻomaikaʻi i ka formability

ʻO ka hoʻomaʻamaʻa ʻana i ka wela i ka pae kūpono o ke kila kila e hiki ai ke maʻalahi i ka hoʻolālā ʻana a me ka hoʻohana ʻana me ka ʻole o ka mālama ʻana i ka corrosion.

Nā Paʻakikī o ka Hoʻomaʻamaʻa ʻana i ka Wela Kuleana

ʻOiai ka maikaʻi, pono e mālama pono ʻia ka mālama ʻana i ka wela kila stainless:

• Ka wela nuihiki ke alakaʻi i ka ulu ʻana o ka palaoa a hoʻemi i ka paʻakikī

• ʻO ka ua carbidehiki ke hōʻemi i ka pale ʻana i ka corrosion ma nā kila austenitic inā ʻaʻole hoʻomālili pono

• ʻO ka hoʻoneʻe ʻana a me ka warpinghiki ke hana inā ʻaʻole like ka hoʻoluʻu ʻana

• ʻO ka ʻoki ʻia ʻana o ka ʻili a me ka scalingmakemake paha i ka pickling ma hope o ka mālama ʻana a i ʻole ka passivation

ʻO ia ke kumu he mea nui e hana pū me nā mea hoʻolako waiwai a me nā loea lapaʻau wela. Ma kasakysteel, ke hāʻawi nei mākou i nā mea ʻelua maka a me ke kākoʻo ʻenehana e hōʻoia i ka hana maikaʻi loa.

Nā noi e koi ana i ke kila kuʻehiʻe wela

Hoʻohana nui ʻia nā kila kulika i ka wela i:

• ʻO nā lau turbine a me nā mea ʻenekini

• ʻO nā mea hana hoʻomaʻamaʻa a me nā implants lapaʻau

• Nā bearings a me nā kumu

• ʻO nā kiwi, nā pāpaʻi, a me nā mea hana kaomi

• Nā mea hoʻopaʻa ikaika kiʻekiʻe a me nā pūnāwai

Inā makemake ʻoe i ka pale ʻana i ka corrosion, ka ikaika, a i ʻole ke kūpaʻa ʻana, ʻo ke koho ʻana i ka pae kila kila kila i mālama ʻia me ka wela ke kī i ka hana mau loa.

Ka hopena

ʻAe, kila kilahikie mālama i ka wela—ma muli o ka papa a me ka hopena i makemake ʻia. ʻOiai ʻaʻole paʻakikī nā māka austenitic a me ka ferritic e ka mālama ʻana i ka wela, hiki ke mālama ʻia nā ʻano paʻakikī martensitic a me ka ua i ka wela e loaʻa ai ka ikaika kiʻekiʻe a me ka paʻakikī.

Ke koho ʻana i ke kila kila no kāu noi, pono e noʻonoʻo ʻaʻole wale i ka pale ʻana i ka corrosion akā inā pono ka mālama wela no ka hana.

sakysteelhāʻawi i kahi koho nui o nā māka kila kila, me nā koho wela-treatable, a hāʻawi i ke alakaʻi akamai e kōkua iā ʻoe e koho i ka hopena maikaʻi loa no kāu papahana. E kelepona mai iā mākou e aʻo hou aʻe e pili ana i kā mākou mau mea pono a me ke kākoʻo.
