Pehea e ʻike ai i ke kila kila

ʻO ke kila kila kekahi o nā mea maʻalahi a hoʻohana nui ʻia ma nā ʻoihana like ʻole-me ke kūkulu ʻana, ka automotive, ka hana ʻai, a me ka ʻenekinia moana. Akā, i nā kūlana honua maoli, e ʻike ana inā he kila kila paha ka metala—a me ka hoʻoholo ʻana i ka meapapaʻo ke kila kila—hiki ke paʻakikī.

Inā ua nīnau ʻoe iā ʻoe iho,pehea e ʻike ai i ke kila kila, e alakaʻi kēia alakaʻi iā ʻoe ma nā ala hilinaʻi loa. Mai ka nānā ʻike maʻalahi a hiki i ka hoʻāʻo holomua, e kōkua mākou iā ʻoe e hoʻokaʻawale i ke kila kila mai nā metala ʻē aʻe a ʻike i kona mau waiwai kikoʻī me ka hilinaʻi.

Hōʻike ʻia kēia ʻatikala hohonu esakysteel, He mea hoʻolako honua o nā huahana kila kila, e hāʻawi ana i nā mea waiwai premium a me ke kākoʻo ʻenehana no ka koi ʻana i nā noi ʻoihana.

No ke aha he mea nui ka ʻike ʻana i ke kila kila?

ʻO ka ʻike inā he kila kuhili paha ka metala—a he aha ia—hiki ke kōkua iā ʻoe:

• E koho i ka mea kūpono no ka hana ʻana a hoʻoponopono paha

• E hōʻoia i ka pale ʻana i ka corrosion a me ka ikaika

• E hoʻokō i nā kūlana ʻoihana a me nā palapala hōʻoia

• Hōʻalo i nā kuhi hewa a i ʻole nā pōʻino palekana

ʻOkoʻa nā ʻano kila kila kila ʻokoʻa i ka pale ʻana i ka corrosion, magnetism, paʻakikī, a me ka pale wela, no laila ʻo ka ʻike kūpono ke kī i ka hana a me ka palekana.

Nā ʻano maʻamau o ke kila kila ʻole e loaʻa iā ʻoe

Ma mua o ka luʻu ʻana i nā ʻano ʻike, kōkua ia e ʻike i nā ʻohana kila kila maʻamau:

• Austenitic (300 series):ʻAʻole-magnetic, maikaʻi loa ke kūpale ʻino (e laʻa, 304, 316)

• Ferritic (400 series):Mākēneki, kūpaʻa ʻino (eg, 409, 430)

• Martensitic (400 series):Magnetic, ʻoi aku ka ikaika, hoʻohana ʻia i nā mea ʻoki a me nā mea hana (e laʻa, 410, 420)

• Duplex:ʻO ka hoʻolālā hui ʻia, ka ikaika kiʻekiʻe a me ke kūpaʻa ʻino (e laʻa, 2205)

sakysteelhāʻawi i kahi koho ākea o kēia mau ʻano kila kila ma ka pepa, ka pā, ka paipu, a me ke ʻano bar - kēlā me kēia ʻenekinia no ka hoʻohana ʻana i ka ʻoihana.

1. Nānā Kiʻi

ʻOiai ʻaʻole paʻa ponoʻī iā ia iho, hiki i nā ʻike ʻike ke kōkua iā ʻoe e hana i kahi kuhi naʻauao.

ʻimi i:

• kala a me ka pau:ʻO ke kila kila ma ke ʻano maʻamau ke ʻano hina-hinahina me ka paheʻe, hoʻomanaʻo a i ʻole ka hoʻopau ʻana.

• Kū'ē i ka Rust:ʻOi aku ka maikaʻi o ke kila kila ma mua o ke kila māmā a kalapona paha. Inā maʻemaʻe a ʻeleʻele ka ʻili i loko o kahi kaiapuni maʻemaʻe, ʻo ia paha he kulika.

• Nā hōʻailona a i ʻole nā peʻa:E ʻimi i nā helu ʻike e like me “304″, “316″, a i ʻole “430″ i kālai ʻia a i hoʻopaʻa ʻia ma ka ʻili metala.

Nānā:Hiki ke ʻano like ka alumini poni, no laila e hahai mau ʻia ka nānā ʻana me ka hoʻāʻo hou ʻana.

2. Hoao Magnet

ʻO kahoʻāʻo magnethe ala wikiwiki a maʻalahi hoʻi e hoʻokaʻawale i kekahi mau ʻano o ke kila kila.

Pehea e hana ai:

• E hoʻohana i kahi magnet liʻiliʻi a kau iā ia ma luna o ka metala.

• Inā he metalamākia ikaika, he mea kila ferritic (430) a i ʻole martensitic (410, 420).

• Inā ka magnetʻaʻole pili, a i ʻole nā lāʻau nāwaliwali wale nō, ʻo ia paha ka austenitic stainless steel (304 a i ʻole 316).

memo nui:Hiki i kekahi mau māka austenitic ke lilo i mea hoʻokalakupua ma hope o ka hana anu (kūlou, mīkini), no laila ʻaʻole pono ka hoʻāʻo magnet kāu ala wale nō.

3. Ho'āʻo Spark

ʻO kēia ʻano hana ka wili ʻana i kahi ʻāpana liʻiliʻi o ka metala a me ka nānā ʻana i ke ʻano o ka uila. Hoʻohana maʻamau ia i nā hale kūʻai metala.

ʻO ka hana ʻāhuʻula:

• Kila kohu ʻole:Pōkole, ʻulaʻula-ʻalani ʻulaʻula me ka liʻiliʻi o ka pohā i hoʻohālikelike ʻia me ke kila kalapona

• Ke kila māmā:ʻO nā ʻōpuʻu melemele ʻulaʻula me ka nui o ka pohā

• Mea kila kila:ʻO nā ʻulaʻula keʻokeʻo lōʻihi me nā huelo ʻoki

E hana wale i kēia ho'āʻo ma kahi wahi palekana me ka pale maka pono.sakysteelpaipai ʻia kēia ʻano hana no nā poʻe loea i aʻo ʻia wale nō.

4. Ho'āʻo Kemika

Hiki i nā ho'āʻo kemika ke hōʻoia inā he kila kuhili paha ka metala a i kekahi manawa e hoʻoholo i ka pae kikoʻī.

a. Hoʻāʻo ʻAka Nitric

Kūleʻa ke kila kila i ka waikawa nitric, ʻoiai ke kila kalapona ʻaʻole.

• E noi i kekahi mau kulu oʻakika nitric concentratedi ka ili metala.

• Ina ka metalaʻaʻole pane, he kila kuhili paha.

• Ina ianā ʻōhū a i ʻole nā ʻulaʻula, he kila kalapona paha.

b. Ho'āʻo Molybdenum

Hoʻohana ʻia e hoʻokaʻawale i waena304a316kila kohu ʻole. Loaʻa i ka 316 ka molybdenum no ka hoʻomaikaʻi ʻana i ka pale ʻana i ka corrosion.

• E hoʻohana i kahi pahu hoʻāʻo wahi molybdenum (loaʻa ma ke kālepa).

• E hoʻopili i ka reagent i ka ʻili metala.

• A hoʻololi kalahōʻike i ka loaʻa ʻana o ka molybdenum (316).

Pono kēia mau ho'āʻo no ka ʻike pololei ʻana i nā hoʻonohonoho mana o ka maikaʻi a i ka wā o ka nānā ʻana i nā mea.

5. XRF Analyzer (Kōkua)

X-ray fluorescence (XRF)ʻO nā mea anaana he mau mea paʻa lima hiki ke ʻike koke i kahoʻohui kemika pololeio ke kila kila.

• Hāʻawi i kahi haʻihaʻi alloy piha me ka chromium, nickel, molybdenum, a me nā mea hou aku

• Maikaʻi no ka hoʻokaʻawale ʻana a me ka hōʻoia ʻana i nā wahi ʻoihana

• Hoʻohana maʻamau e nā mea hoʻolako metala, mea hana hou, a me nā mea nānā

sakysteelhoʻohana i ka hoʻāʻo XRF e hōʻoia i ka hoʻohui ʻana i nā mea a me ka hōʻoia i ka pololei no nā hoʻopuka kila kila.

6. ʻO ka hoʻāʻo ʻana i ke kaumaha a me ke kaumaha

ʻOi aku ka paʻa a ʻoi aku ke kaumaha o ke kila kila ma mua o ka alumini a i ʻole kekahi mau ʻāpana māmā ʻē aʻe.

E hoʻohālikelike:

• E ana i ka leo i ʻike ʻia (e laʻa, 1 cm³) o ka mea

• E kaupaona ʻia a hoʻohālikelike i ka nui o ke kila kila (~ 7.9 g/cm³)

• Inā ʻoi aku ka māmā, he alumini paha ia (density ~2.7 g/cm³)

Kōkua kēia hoʻāʻo e pale i ka ʻike hewa ʻana i ka alumini i poni ʻia e like me ke kila kila.

7. Ho'āʻo ʻino (Ma muli o ka manawa)

Inā hoʻokomo ʻia ka metala i loko o kahi pōʻino (e laʻa, ke kai a mea kanu kemika paha), e nānā i ke ʻano o ka hana ʻana i ka manawa:

• 304 kuhiliʻolehiki i ka ʻōpala ma nā wahi waiwai nui o ka chloride

• 316 kuhiliʻolee kūpaʻa mau ma muli o ka molybdenum

• Ke kila māmāe ʻike ʻia ka ʻōpala i loko o nā lā

ʻAʻole kūpono kēia no ka ʻike wikiwiki akā kōkua i ka hōʻoia ʻana i ka hana o nā mea i hoʻokomo ʻia.

I ka wa e launa aku ai me ka Oihana

Inā ʻaʻole ʻoe maopopo e pili ana i ka ʻike o kāu metala, ʻoi loa no nā noi koʻikoʻi (nā moku kaomi, nā lako meaʻai, nā mea hoʻonoho o waho), e nīnau mau i kahi lab metallurgical a mea hoʻolako e like mesakysteel.

Hiki iā lākou ke hāʻawi:

• palapala hōʻoia waiwai (MTC)

• Hōʻoia papa

• ʻO ke koho loea e pili ana i nā kūlana ʻoihana (ASTM, EN, ISO)

Hōʻuluʻulu manaʻo o ka ʻike

Ka hopena: Pehea e ʻike ai i ke kila kila me ka hilinaʻi

He mea nui ka ʻike pono ʻana i ke kila kila no ka hōʻoia ʻana i ka hana o ka huahana, ka hoʻokō, a me ka palekana. Me ka hui pū ʻana o nā hoʻāʻo maʻamau e like me ka magnetism a me ke kaumaha, a me nā ʻano holomua e like me ka nānā ʻana i ke kemika a i ʻole ka nānā ʻana XRF, hiki iā ʻoe ke hoʻoholo me ka hilinaʻi inā he kila kila ka metala—a ʻo ke kuhikuhi ʻana i ka papa.

Inā ʻoe e hoʻoponopono nei i kahi ʻōnaehana meaʻai, nā ʻāpana hoʻonohonoho wili, a i ʻole ke kiʻi ʻana i nā lako kai,ʻike pono i ka ʻike kila kila.A i ka wā e loaʻa ai i nā mea kila kila kiʻekiʻe,sakysteelʻo ia ka inoa ʻoihana hilinaʻi.
