ʻO wai ka ʻoi aku ka maikaʻi, ʻo ka hao hao a i ʻole ke kila kila?

I ka wā e koho ai i ke ʻano kila kūpono no kāu papahana, hoʻoholo pinepine ʻia ka hoʻoholokalapona kila vs. kuhiliʻole kila. Hoʻohana nui ʻia nā mea ʻelua ma waena o nā ʻoihana - mai ke kūkulu ʻana a me ka hana ʻana i nā mea kaʻa a me nā mea kūʻai aku. ʻOiai ke ʻano like lākou, ʻo ke kila kalapona a me ke kila kuhili ʻokoʻa ke ʻano kemika ʻokoʻa, nā waiwai mechanical, ka pale ʻana i ka corrosion, a me nā kumu kūʻai. No laila, ʻoi aku ka maikaʻi? ʻO ka pane e pili ana i kāu mau koi noi kikoʻī. Ma kēia ʻatikala, e hoʻohālikelike mākou i ke kila kalapona a me ke kila kila e kōkua iā ʻoe e hana i ka koho ʻike.

1. Ka Hui Kumu

He mea koʻikoʻi ka hoʻomaopopo ʻana i ke ʻano o kēlā me kēia ʻano kila no ka loiloi ʻana i kona ʻano.

hao kalapona:

• Hoʻokumu mua ʻia me ka hao a me ke kalapona (a hiki i ka 2.1%)

• Hiki ke hoʻokomo i ka nui o ka manganese, silika, a me ke keleawe

• ʻAʻohe mea chromium koʻikoʻi

Kila kohu ʻole:

• Loaʻa i ka hao, carbon, a ma ka liʻiliʻi loa10.5% chromium

• Hoʻohui pinepine ʻia me ka nickel, molybdenum, a me ka nitrogen

• Hoʻokumu ka ʻike chromium i kahi papa passive no ka pale ʻana i ka corrosion

ʻO ka hele ʻana o ka chromium ke kī ʻokoʻa e hāʻawi ai i ke kila kila i kāna mau waiwai pale ʻino.

2. Ke kū'ē i ka corrosion

Kila kohu ʻole:

• Kūleʻa kūʻokoʻa i ka pala a me ka corrosion

• He kūpono no nā kaiapuni kai, ka hoʻoheheʻe kemika, a me nā noi meaʻai

• Hana maikaʻi i loko o nā kūlana acidic, humid, a i ʻole saline

hao kalapona:

• Hiki i ka ʻōpala a me ka ʻino ke ʻole i uhi ʻia a pena ʻia paha

• Pono paha ka galvanization a i ʻole ka hoʻopau pale no ka hoʻohana ʻana i waho

• ʻAʻole ʻōlelo ʻia no nā hoʻonohonoho kiʻekiʻe-makū a corrosive

Ka hopena:Lanakila ke kila kila ma nā kaiapuni kahi e hopohopo nui ai ka corrosion.

3. Ka ikaika a me ka paakiki

Hiki ke mālama ʻia nā mea ʻelua e hoʻomaikaʻi i kā lākou hana mechanical.

hao kalapona:

• ʻOi aku ka ikaika a ʻoi aku ka paʻakikī ma mua o ke kila kila

• ʻOi aku ka ikaika tensile, ʻoi aku ka maikaʻi ma nā māka kalapona kiʻekiʻe

• Manaʻo ʻia no nā ʻāpana hana, nā lau, a me nā mea hana kiʻekiʻe

Kila kohu ʻole:

• ʻO ka ikaika kūpono ke hoʻohālikelikeʻia me ke kila kalapona

• ʻOi aku ka maʻalahi o nā kila kuhili ʻole Austenitic (e laʻa, 304, 316) akā ʻaʻole ikaika.

• Hiki i nā māka Martensitic a me duplex ke hoʻokō i nā pae ikaika kiʻekiʻe

Ka hopena:ʻOi aku ka maikaʻi o ke kila kalapona no nā noi e koi ana i ka ikaika a me ka paʻakikī.

4. Nānā a Hoʻopau

Kila kohu ʻole:

• ʻAlohi maoli a paheʻe

• Hiki ke hoʻonaniʻia i ke aniani a iʻole ka hopena satin

• Mālama i kona helehelena i ka manawa

hao kalapona:

• Hoʻopau polū a matte ke ʻole i uhi ʻia a pena ʻia

• Kūleʻa i ka oxidation o ka ʻili a me ka ʻili

• Pono ka mālama ʻana e mālama i ka nani

Ka hopena:Hāʻawi ke kila kila kila maikaʻi i ka hoʻopau ʻana i ka ʻili a me ka hoʻopiʻi nani.

5. Hoʻohālikelike Kūʻai

hao kalapona:

• ʻOi aku ke kumukūʻai ma muli o ka haku mele ʻana a me ka haʻahaʻa haʻahaʻa

• ʻO ke kumu kūʻai kūpono no nā papahana hoʻolālā kiʻekiʻe a nui paha

• Maikaʻi i ka mīkini a hana

Kila kohu ʻole:

• ʻOi aku ke kumu kūʻai mua ma muli o nā mea hoʻohui like e like me ka chromium a me ka nickel

• Hiki ke hoʻemi i nā kumukūʻai mālama lōʻihi ma muli o ka pale ʻana i ka ʻōpala

Ka hopena:No nā papahana pili kālā, ʻoi aku ka maikaʻi o ke kila kalapona.

6. Hiki i ka hana a me ka Weldability

hao kalapona:

• ʻOi aku ka maʻalahi o ka ʻoki, hana, a wili

• ʻAʻole liʻiliʻi ka liʻiliʻi ma lalo o ka wela nui

• He kūpono no nā kaiapuni hana wikiwiki

Kila kohu ʻole:

• Pono nā mea hana kūikawā a me nā ʻenehana

• Hiki i ka hoʻonui ʻana i ka wela ke kumu i ka warping i ka wā wili

• Pono paha nā lāʻau lapaʻau ma hope o ka weld e pale ai i ka pala

Ka hopena:ʻOi aku ka kala kala a me ka maʻalahi o ka hana ʻana.

7. Nā noi

Hoʻohana maʻamau o Carbon Steel:

• Nā alahaka a me nā hale

• ʻO nā paipu a me nā pahu

• ʻO nā mea hana ʻoki a me nā ʻāpana mīkini

• Chassis kaʻa a me nā mea hana

Nā hoʻohana maʻamau o ke kila kila:

• Mea hana meaʻai a mea inu

• ʻO nā mea hana lapaʻau a me nā mea hana hoʻokalakupua

• Nā hale kai a me nā paepae o waho

• Nā lako hale a me nā lako kīhini

sakysteelhoʻolako i nā huahana kalapona a me nā mea kila kila e hoʻokō i nā koi ʻoihana like ʻole.

8. Nā Manaʻo Kaiapuni a me ke Ola

Kila kohu ʻole:

• 100% hiki ke hana hou

• Non-reactive me ka meaʻai a me ka wai

• ʻAʻole pono nā uhi ʻona a i ʻole nā lāʻau lapaʻau

hao kalapona:

• Pono paha nā pale pale i loaʻa nā kemika

• Kūleʻa i ka ʻino e pili ana i ka corrosion

• Hiki ke hana hou akā hiki ke komo i nā mea pena a i uhi ʻia

Ka hopena:ʻOi aku ka maikaʻi o ke kila kila a me ka maʻemaʻe.

9. ʻO ke ola a me ka mālama

Kila kohu ʻole:

• Haʻahaʻa mālama

• ʻO ke ola lawelawe lōʻihi ma nā wahi paʻakikī

• Hoʻohaʻahaʻa liʻiliʻi i ka manawa

hao kalapona:

• Pono i ka pena maʻamau, ka uhi ʻana, a i ʻole ka nānā ʻana

• Hiki i ka ʻōpala ke mālama ʻole ʻia

• ʻOi aku ka pōkole o ke ola ma nā kūlana corrosive

Ka hopena:Hāʻawi ke kila kila ʻoi aku ka maikaʻi a me ka haʻahaʻa o ke kumukūʻai ola.
