440C Pahu kila kila
ʻO ka wehewehe pōkole:
ʻO 440C ke kila kila he kiʻekiʻe-carbon martensitic stainless steel i ʻike ʻia no kona paʻakikī maikaʻi loa, ʻaʻahu kūʻokoʻa, a me ka pale ʻana i ka corrosion.
ʻO nā pahu kila 440C:
440C kuhiliʻole kila hiki ke paakiki e loaa kiʻekiʻe kiʻekiʻe o ka paakiki, maʻamau ma kahi o 58-60 HRC (Rockwell hardness scale). No ka 400 moʻo o kuhiliʻole steels, i ikeia e ka loaʻa kiʻekiʻe kalapona maʻiʻo, maʻamau a puni 0.60-1.20% , a me ke kūpaʻa corrosion haʻahaʻa. He kūpaʻa maikaʻi loa ia no ka hoʻohana ʻana e like me nā bearings, nā mea ʻoki ʻoki, nā mea ʻokiʻoki, a me nā ʻāpana valve. hāʻawi maikaʻi i ka pale ʻana i ka corrosion ma nā wahi haʻahaʻa. ʻOi aku ka pale ʻana i ka corrosion ma mua o nā kila kalapona kiʻekiʻe ma muli o kona ʻano chromium.440C hiki ke hoʻomaʻamaʻa ʻia ke kila kila no ka loaʻa ʻana o nā waiwai mechanical i makemake ʻia.

Nā hiʻohiʻona a me nā pono:
•Ma hope o ka hoʻomaʻamaʻa wela kūpono, hiki i ka 440C stainless steel ke hoʻokō i kahi kiʻekiʻe o ka paʻakikī, maʻamau ma waena o 58-60 HRC, e kūpono ana i nā noi e koi ana i ka paʻakikī kiʻekiʻe.
•Ma muli o kāna ʻano kalapona kiʻekiʻe a me nā waiwai mālama wela maikaʻi loa, hōʻike ʻo 440C stainless steel i ke kūpaʻa ʻaʻahu koʻikoʻi, kūpono ia i nā noi like ʻole e like me nā mea ʻoki ʻoki, nā bearings, etc.
•ʻOiai ʻaʻole like me ka corrosion-resistant e like me austenitic stainless steels (eg, 304, 316), 440C stainless steel ke hāʻawi mau nei i ka pale ʻana i ka corrosion maikaʻi i nā wahi kūpono, ma muli o kona kiʻekiʻe chromium maʻiʻo, i hana i ka pale chromium oxide ma luna.
•Hiki ke hana maikaʻi ʻia ke kila kila 440C ma lalo o nā kūlana kūpono e hoʻokō i nā koi ʻāpana like ʻole. Eia nō naʻe, ma muli o kona paʻakikī kiʻekiʻe a me ka ikaika, paʻakikī paha ka mīkini a koi i nā kaʻina hana a me nā mea hana kūpono.
•Hōʻike ʻo 440C stainless steel i ke kūpaʻa maikaʻi o ka wela kiʻekiʻe, e mālama ana i kona paʻakikī a me ke kūpaʻa ʻana ma lalo o nā kūlana wela kiʻekiʻe, e kūpono ana i nā noi ma nā wahi wela kiʻekiʻe.
•Hiki ke hoʻoponopono ʻia nā ʻano mechanical o 440C stainless steel ma o ka mālama ʻana i ka wela, e like me ka paʻakikī, ka ikaika, a me ka paʻakikī, e hoʻokō i nā koi noi kikoʻī.
No ke aha e koho ai iā mākou?
•Hiki iā ʻoe ke loaʻa ka mea kūpono e like me kāu koi ma ka liʻiliʻi loa o ke kumu kūʻai.
•Hāʻawi pū mākou i nā Reworks, FOB, CFR, CIF, a me nā kumukūʻai hoʻopuka puka i ka puka. Manaʻo mākou iā ʻoe e hana i ka hana no ka hoʻouna ʻana e ʻoi aku ka waiwai.
•Hiki ke hōʻoia ʻia nā mea a mākou e hāʻawi ai, mai ka palapala hōʻike maka a hiki i ka ʻōlelo kikoʻī hope. (E hōʻike ʻia nā hōʻike ma ke koi)
•Ke hōʻoiaʻiʻo nei mākou e hāʻawi i kahi pane i loko o 24 mau hola (maʻamau i ka hola hoʻokahi)

He aha ka 440C Stainless Steel?
Hāʻawi ka 440C stainless steel i ke koena o ke kūpaʻa ʻaʻahu maikaʻi a me ke kūpaʻa corrosion haʻahaʻa i nā wahi haʻahaʻa, me ka paʻakikī maikaʻi loa. Kaʻana like ia me ka 440B papa akā loaʻa i kahi maʻi kalapona kiʻekiʻe iki, ka hopena i ka ʻoi aku ka paʻakikī akā ua hoʻemi iki ke kūpaʻa corrosion i hoʻohālikelike ʻia me 440B. Hiki iā ia ke hoʻokō i ka paʻakikī a hiki i ka 60 Rockwell HRC a kūʻē i ka corrosion i loko o nā wahi ʻenehana maʻamau a me nā ʻenehana haʻahaʻa, me ke kūpaʻa maikaʻi loa i loaʻa ma lalo o 400°C tempering temperature. He mea koʻikoʻi ka hoʻomākaukau ʻana i ka ʻili no ka pale ʻana i ka corrosion maikaʻi loa, pono e hoʻoneʻe i ka unahi, nā lubricants, nā ʻāpana haole, a me nā uhi. ʻO kona ʻano kalapona kiʻekiʻe e hiki ai ke hana like me nā māka kila kiʻekiʻe-wikiwiki annealed.
440C mea hao kila poepoe noi:
Hoʻohana nui ʻia nā ʻāpana kila kila 440C i ka hana ʻana i ka pahi, nā bearings, nā mea hana a me nā mea ʻokiʻoki, nā mea lapaʻau, nā ʻāpana valve, a me nā mea hana ʻoihana, kahi o ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, a me ke kūpaʻa corrosion e hoʻolilo iā lākou i nā koho kūpono no nā mea koʻikoʻi e koi ana i ka maikaʻi. ka hana a me ka lōʻihi lōʻihi.
Kuʻihao ʻana o ke kila kila 440C:
Ma muli o kona paʻakikī kiʻekiʻe a me ka maʻalahi o ka paʻakikī o ka ea, ʻaʻole pinepine ka wili ʻana o 440C stainless steel. Eia naʻe, inā pono ka wiliwili, pono e hoʻomaʻamaʻa mua i ka mea i 260°C (500°F) a e hana i ka hoʻomaʻamaʻa post-weld annealing ma 732-760°C (1350-1400°F) no 6 mau hola, a ukali ʻia e ka hoʻoluʻu ʻana o ka umu e pale ai i ka haki ʻana. No ka hōʻoia ʻana i nā ʻano mechanical like i loko o ka weld e like me ka metala kumu, pono e hoʻohana ʻia nā mea hoʻohana wili me nā mea like. ʻO kahi ʻē aʻe, hiki ke noʻonoʻo ʻia ʻo AWS E/ER309 he koho kūpono.
ʻO kā mākou mau mea kūʻai
Manaʻo manaʻo mai kā mākou mea kūʻai mai
400 moʻo kuhiliʻole koʻokoʻo i kekahi mau pono kaulana, e hoʻolilo iā lākou i makemake i nā noi like ʻole. ʻO nā koʻokoʻo kila he hana manuahi, e hōʻike ana i ka machinability maikaʻi loa. ʻO kēia hiʻohiʻona ka mea maʻalahi iā lākou e ʻoki, hana, a me ka hana.400 series stainless steel rods e hana maikaʻi ma ke ʻano o ka ikaika a me ka paʻakikī, kūpono no nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa ʻaʻahu, e like me ka hana ʻana i nā ʻāpana mechanical.
Hoʻopili:
1. He mea koʻikoʻi ka hoʻopaʻa ʻana ma ka hihia o ka hoʻouna ʻana i ka honua kahi e hele ai ka lawe ʻana ma nā ala like ʻole e hiki ai i ka hopena hope loa, no laila ke kau nei mākou i ka hopohopo kūikawā e pili ana i ka ʻeke.
2. Hoʻopili ʻo Saky Steel i kā mākou waiwai ma nā ʻano he nui e pili ana i nā huahana. Hoʻopili mākou i kā mākou huahana ma nā ʻano he nui, e like me,
