Nā ʻano a me nā noi o ke kila kila 440C

He nui nā papa o nā kila kila, ua hana ʻia kēlā me kēia e hāʻawi i nā hiʻohiʻona hana kikoʻī. I waena o lākou,440C kila kilakū i waho ma ke ʻano hekila kila martensitic kiʻekiʻe-kalapona, chromium kiʻekiʻeʻike ʻia no konapaʻakikī maikaʻi loa, kūpaʻa ʻaʻahu, a me ke kūpaʻa ʻana i ka palaHoʻohana nui ʻia ia i nā noi hana kiʻekiʻe kahi e koʻikoʻi ai ka paʻa ʻana o ka lihi, ka ikaika, a me ke kūpaʻa.

Ke ʻimi nei mākou i kanā ʻano, nā waiwai mechanical, a me nā hoʻohana maʻamauo ke kila kila 440C. Inā ʻoe e komo ana i ka hoʻolālā ʻoihana, ka hana ʻana, nā mea hana, a i ʻole ka hana ʻana i nā mea lapaʻau, e hāʻawi kēia ʻatikala i nā ʻike waiwai nui i ke kumu he koho kaulana ke kila kila 440C no nā noi koi.

At sakysteel, loea mākou i ka hoʻolako ʻana i ke kila kila 440C kiʻekiʻe loa i nā ʻano like ʻole a me nā nui, e hoʻokō ana i nā pono o nā ʻoihana ma ka honua holoʻokoʻa.sakysteelno ke kākoʻo loea, ke kumu kūʻai hilinaʻi, a me nā hoʻonā mea i hana kūikawā ʻia.

1. He aha ke kila kila 440C?

440C kila kilahemea hoʻohuihui kila kila martensiticme nā pae kiʻekiʻe okalapona a me chromiumHe ʻāpana ia o ka moʻo 400 a ʻo ia ka papa kūpaʻa loa i ka palaho ma waena o nā kila kila 440 (440A, 440B, a me 440C).

Ka Hoʻonohonoho Maʻamau o 440C:

• Kalapona (C): 0.95% – 1.20%

• Chromium (Cr): 16.0% – 18.0%

• Manganese (Mn): ≤ 1.0%

• Silika (Si): ≤ 1.0%

• Molibdenum (Mo): Koho i kekahi mau mana no ka paʻakikī i hoʻohui ʻia

• Nikala (Ni)Nā nui liʻiliʻi

• Hao (Fe)Kaulike

ʻAe kēia ʻano hana i ka 440C e hiki akupaʻakikī kiʻekiʻe (a hiki i ka 60 HRC)ke mālama ʻia me ka wela, ʻoiai e hāʻawi mau ana i ke kūpaʻa kūpono i ka pala.

2. Nā ʻano koʻikoʻi o ke kila kila 440C

a) Paʻakikī a me ka ikaika kiʻekiʻe

Ke mālama pono ʻia ka wela, hiki i ka 440C ke hoʻokōNā pae paʻakikī Rockwell ma waena o 58 a 60 HRC, e lilo ia i hoʻokahi o nā kila kila paʻakikī loa i loaʻa. ʻO kēia ka mea e kūpono ai no:

• Nā mea hana ʻokiʻoki

• Nā ʻāpana hali

• Nā ʻāpana kikoʻī

b) Kū'ē maikaʻi loa i ka hoʻohana ʻana a me ka abrasion

Ma muli o kona nui o ke kalapona,440Chōʻikeke kūpaʻa koʻikoʻi i ka ʻaʻahu ʻili, ke ʻano o ka lihi, a me ka luhi mīkini — kūpono no nā hana paheʻe a hoʻohuli paha.

c) Kū'ē maikaʻi i ka palaho

ʻOiai ʻaʻole i kūpaʻa i ka pala e like me nā kila kila series 300, hana maikaʻi ʻo 440C i nā wahi pala iki a maikaʻi ʻole. Hiki iā ia ke kū'ē i:

• ka makū

• Nā waikawa meaʻai

• Nā kemika palupalu

Eia nō naʻe, ʻo iaʻaʻole i ʻōlelo ʻiano nā noi kai a i ʻole nā ​​​​​​hana chloride kiʻekiʻe me ka ʻole o ka mālama ʻili kūpono.

d) Magnetic a me ka Wela-Treatable

ʻO 440Cmakenekama nā kūlana āpau a hiki kehoʻopaʻakikī ʻia ma o ka mālama wela maʻamau, e maʻalahi ai ka hoʻololi ʻana no nā noi mechanical a me nā ʻano kūkulu like ʻole.

3. Nā Waiwai Mekanika o 440C

ʻO 440C kapaʻakikī loaa ʻo ka hapa nuikūpaʻa i ke komo ʻanai waena o kēia mau mea, ʻoiai me ke kūpaʻa haʻahaʻa iki.

Hopena

440C kila kilahe koho kiʻekiʻe loa ia i ka wāpaʻakikī kūikawā, ke kūpaʻa ʻana i ke komo ʻana, a me ke kūpaʻa kūpono i ka palahopono. Hoʻohana nui ʻia ia i nā ʻoihana mai ka aerospace a me ke kaʻa a hiki i ka lāʻau lapaʻau a me nā mea hana. ʻO kona hiki ke hoʻopaʻakikī ʻia i nā pae koʻikoʻi me ka mālama ʻana i ka pale kūpono o ka palaho e lilo ia i hoʻokahi o nā mea nui loanā kila kila martensitic like ʻoleloaʻa.

ʻO ka hoʻomaopopo ʻana i kona mau ʻano e hiki ai i nā ʻenekinia a me nā mea kūʻai ke hana i ke koho mea maikaʻi loa no nā noi lōʻihi a hana kiʻekiʻe.

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