ʻO 440C Nā ʻano a me nā mea hoʻohana

Hele mai nā kila kila ma nā māka he nui, ua hoʻolālā ʻia kēlā me kēia mea e hāʻawi i nā hiʻohiʻona hana kikoʻī. Iwaena o lakou,440C kila kilakū i waho ma ke ʻano hekalapona kiʻekiʻe, kiʻekiʻe-chromium martensitic kila kilakaulana no konaʻo ka paʻakikī maikaʻi loa, ka pale ʻana i ke aahu, a me ka pale ʻana i ka corrosion. Hoʻohana nui ʻia ia i nā noi hana kiʻekiʻe kahi koʻikoʻi ka paʻa ʻana o ka lihi, ka ikaika, a me ka lōʻihi.

Huli mākou i kanā hiʻohiʻona, nā waiwai mechanical, a me nā hoʻohana maʻamauo 440C kila kila. Inā ʻoe e pili ana i ka hoʻolālā ʻenehana, ka hana ʻana, nā mea hana, a i ʻole ka hana ʻana i nā mea lapaʻau, e hāʻawi kēia ʻatikala i nā ʻike koʻikoʻi i ke kumu he koho kaulana ʻo 440C stainless steel no nā noi noi.

At sakysteel, kūikawā mākou i ka hāʻawiʻana i ke kila kila 440C maikaʻi loa i nāʻano likeʻole a me nā nui, e hālāwai ana i nā pono o nāʻoihana ma ka honua holoʻokoʻa. Hoʻopilisakysteelno ke kākoʻo akamai, ka ʻimi ʻana i ka hilinaʻi, a me ka hoʻoponopono waiwai.

1. He aha ka 440C Stainless Steel?

440C kila kilahe akila kuhiliʻole martensiticme nā pae kiʻekiʻe okalapona a me ka chromium. He ʻāpana ia o ka moʻo 400 a ʻo ia ka papa kūpaʻa ʻoi loa i ka corrosion ma waena o nā 440 stainless steels (440A, 440B, a me 440C).

Huina maʻamau o 440C:

• Kalapona (C): 0.95% – 1.20%

• Chromium (Cr): 16.0% – 18.0%

• Manganese (Mn): ≤ 1.0%

• Silika (Si): ≤ 1.0%

• Molybdenum (Mo): He koho i kekahi mau mana no ka paʻakikī hou

• Nikela (Ni): Helu helu

• Hao (Fe): Kaulike

Hiki i kēia haku mele ke hiki i 440Cpaʻakikī kiʻekiʻe (a hiki i 60 HRC)i ka wā e mālama ʻia ai ka wela, ʻoiai e hāʻawi mau ana i ka pale ʻana i ka corrosion.

2. ʻO nā hiʻohiʻona nui o 440C Stainless Steel

a) Paʻa kiʻekiʻe a me ka ikaika

Ke mālama pono ʻia ka wela, hiki i ka 440C ke loaʻaNā pae paʻakikī o Rockwell ma waena o 58 a 60 HRC, e hana ana ia i kekahi o na kila kuhiliʻole paʻakikī loa i loaʻa. He kūpono kēia no:

• Nā mea hana ʻoki

• Nā ʻāpana lawe

• ʻāpana pololei

b) ʻAʻahu maikaʻi loa a me ka pale ʻana

Ma muli o kona kiʻekiʻe o ke kalapona,440Chōʻikekūʻē kūʻē i ka ʻaʻahu o luna, deformation lihi, a me ka luhi mīkini - kūpono no ka hoʻoheheʻe ʻana a i ʻole ka hoʻololi ʻana i nā noi.

c) Kū'ē Kū'ē maikaʻi

ʻOiai ʻaʻole like me ka corrosion-resistant e like me 300 series stainless steels, 440C hana maikaʻi ma ka ʻoluʻolu a me ka haʻahaʻa corrosive kaiapuni. Hiki ke kū'ē:

• Māmā

• ʻAikiʻai meaʻai

• Kemika maʻalahi

Eia naʻe, ʻo iaʻaʻole ʻōlelo ʻiano nā noi kai a i ʻole kiʻekiʻe-chloride me ka mālama ʻole ʻana i ka ʻili.

d) Mākēneki a me ka wela-Treatable

ʻO 440Cmākiama nā kūlana a pau a hikipaʻakikī ma o ka mālama wela maʻamau, e maʻalahi ka hoʻololi ʻana no nā ʻano hana mechanical a me ka hoʻolālā.

3. Pono Mechanical o 440C

ʻO 440C kapaakiki loaa nui loapale ʻaʻahui waena o kēia mau mea, ʻoiai me ka haʻahaʻa haʻahaʻa haʻahaʻa.

Ka hopena

440C kila kilahe koho kiʻekiʻe i ka wā'o'ole'a 'o'ole'a, 'au'au pale 'ana, a me ka 'inokoi ʻia. Hoʻohana nui ʻia ia i nā ʻoihana mai ka aerospace a me ka automotive i ka lāʻau lapaʻau a me nā mea hana. ʻO kona hiki ke paʻakikī i nā pae kiʻekiʻe ʻoiai ka mālama ʻana i ka pale corrosion kūpono e lilo ia i mea nui loanā kila kila martensitic versatileloaʻa.

ʻO ka hoʻomaopopo ʻana i kāna mau hiʻohiʻona e hiki ai i nā ʻenekinia a me nā mea kūʻai aku ke hana i ka koho waiwai maikaʻi loa no nā noi lōʻihi, hana kiʻekiʻe.

No ke kila kila 440C kiʻekiʻe me nā palapala hōʻoia piha a me nā lawelawe waiwai e like me ka ʻoki maʻamau, polishing, a me ka mālama wela,sakysteelʻo kāu mea hoʻolako hilinaʻi. Hoʻopilisakysteeli kēia lā e kiʻi i kahi ʻōlelo a kūkākūkā paha i kāu mau koi papahana.
