Pā kila kila 440C
Wehewehe Pōkole:
ʻO ke kila kila kila 440C kahi kila kila martensitic kalapona kiʻekiʻe i ʻike ʻia no kona paʻakikī maikaʻi loa, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa ʻana i ka pala.
Nā Pā Kila Kila 440C:
Hiki ke hoʻopaʻakikī ʻia ke kila kila 440C e hoʻokō i nā pae paʻakikī kiʻekiʻe, ma kahi o 58-60 HRC (Rockwell hardness scale). No loko ia o ka moʻo 400 o nā kila kila, i hōʻike ʻia e ka loaʻa ʻana o ka nui o ke kalapona, ma kahi o 0.60-1.20%, a me ke kūpaʻa ʻana i ka pala. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana, e kūpono ai no nā noi e like me nā bearings, nā mea ʻokiʻoki, nā mea hana ʻokiʻoki, a me nā ʻāpana valve. ʻOiai ʻaʻole ia e like me ke kūpaʻa i ka pala e like me nā kila kila austenitic (e laʻa, 304, 316), hāʻawi ʻo 440C i ke kūpaʻa maikaʻi i ka pala i nā wahi akahai. ʻOi aku ka kūpaʻa o ka pala ma mua o nā kila kalapona kiʻekiʻe ʻē aʻe ma muli o kāna ʻike chromium. Hiki ke mālama ʻia ke kila kila 440C i ka wela e hoʻokō i nā waiwai mechanical i makemake ʻia.

Nā Hiʻohiʻona a me nā Pōmaikaʻi:
•Ma hope o ka mālama ʻana i ka wela kūpono, hiki i ke kila kila 440C ke hoʻokō i kahi pae paʻakikī kiʻekiʻe, ma waena o 58-60 HRC, e kūpono ana no nā noi e pono ai ka paʻakikī kiʻekiʻe.
•Ma muli o ke kiʻekiʻe o ke kalapona a me nā waiwai lapaʻau wela maikaʻi loa, hōʻike ka kila kila 440C i ke kūpaʻa ʻana i ka ʻaʻahu, e kūpono ai no nā ʻano hana like ʻole e like me nā mea ʻokiʻoki, nā bearings, a pēlā aku.
•ʻOiai ʻaʻole i like ke kūpaʻa i ka pala me nā kila kila austenitic (e like me 304, 316), hāʻawi mau ke kila kila 440C i ke kūpaʻa maikaʻi i ka pala i nā wahi kūpono, ma muli o kona nui o ka chromium, kahi e hana ai i kahi papa pale chromium oxide.
•Hiki ke hana pono ʻia ke kila kila 440C ma lalo o nā kūlana kūpono e hoʻokō ai i nā koi ʻāpana like ʻole. Eia nō naʻe, ma muli o kona paʻakikī a me ka ikaika kiʻekiʻe, he paʻakikī paha ka hana ʻana i ka mīkini a koi ʻia nā kaʻina hana a me nā mea hana kūpono.
•Hōʻike ka kila kila 440C i ke kūpaʻa maikaʻi o ka mahana kiʻekiʻe, e mālama ana i kona paʻakikī a me ke kūpaʻa i ka ʻaʻahu ma lalo o nā kūlana mahana kiʻekiʻe, e kūpono ana no nā noi ma nā wahi mahana kiʻekiʻe.
•Hiki ke hoʻololi ʻia nā waiwai mechanical o ke kila kila 440C ma o ka mālama wela ʻana, e like me ka paʻakikī, ka ikaika, a me ka paʻakikī, e hoʻokō ai i nā koi noi kikoʻī.
No ke aha e koho ai iā mākou?
•Hiki iā ʻoe ke loaʻa i ka mea kūpono e like me kāu koi ma ke kumu kūʻai haʻahaʻa loa.
•Hāʻawi pū mākou i nā kumukūʻai hoʻouna Reworks, FOB, CFR, CIF, a me ka puka a puka. Manaʻo mākou e hana ʻoe i kahi ʻaelike no ka hoʻouna ʻana i mea hoʻokele waiwai loa.
•Hiki ke hōʻoia piha ʻia nā mea a mākou e hāʻawi nei, mai ka palapala hōʻoia hoʻāʻo mea maka a hiki i ka ʻōlelo hope loa o ka dimensional. (E hōʻike ʻia nā hōʻike ma ke koi)
•Hoʻohiki mākou e hāʻawi i kahi pane i loko o 24 mau hola (maʻamau i ka hola hoʻokahi)
•Hāʻawi i ka hōʻike SGS TUV.
•Ua hoʻolaʻa piha mākou i kā mākou mea kūʻai aku. Inā ʻaʻole hiki ke hoʻokō i kāu mau koi ma hope o ka nānā ʻana i nā koho āpau, ʻaʻole mākou e alakaʻi hewa iā ʻoe ma ka hana ʻana i nā ʻōlelo hoʻohiki wahaheʻe e hoʻokumu ai i nā pilina maikaʻi me nā mea kūʻai aku.
•Hāʻawi i ka lawelawe hoʻokahi.
He aha ke kila kila 440C?
Hāʻawi ke kila kila 440C i kahi kaulike o ke kūpaʻa maikaʻi o ka ʻaʻahu a me ke kūpaʻa kaulike i ka palaho i nā wahi akahai, me ka paʻakikī maikaʻi loa. He like ia me ka papa 440B akā he ʻoi aku ka nui o ke kalapona, e hopena ana i ka paʻakikī kiʻekiʻe akā emi iki ke kūpaʻa i ka palaho i hoʻohālikelike ʻia me 440B. Hiki iā ia ke hoʻokō i ka paʻakikī a hiki i ka 60 Rockwell HRC a kūʻē i ka palaho i nā wahi maʻamau o ka home a me nā ʻoihana akahai, me ke kūpaʻa kūpono i loaʻa ma lalo o ka mahana hoʻomehana 400°C. He mea koʻikoʻi ka hoʻomākaukau ʻana o ka ʻili no ke kūpaʻa maikaʻi loa i ka palaho, e pono ai ka wehe ʻana i ka unahi, nā lubricants, nā ʻāpana haole, a me nā uhi. ʻO kona ʻike kalapona kiʻekiʻe e ʻae ai i ka mīkini e like me nā papa kila wikiwiki kiʻekiʻe i hoʻoheheʻe ʻia.
Noi ʻana o ka pā poepoe kila kila 440C:
Hoʻohana nui ʻia nā kaola poepoe kila kila 440C i ka hana pahi, nā bearings, nā mea hana a me nā mea ʻokiʻoki, nā mea lapaʻau, nā ʻāpana valve, a me nā lako ʻoihana, kahi i lilo ai ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa kūpono i ka pala i mau koho kūpono no nā ʻāpana koʻikoʻi e pono ai ka hana maikaʻi loa a me ke kūpaʻa lōʻihi.
Kuʻihao o ke kila kila 440C:
Ma muli o kona paʻakikī kiʻekiʻe a me ka maʻalahi o ka paʻakikī ʻana o ka ea, ʻaʻole pinepine ka hoʻoheheʻe ʻana o ke kila kila 440C. Eia nō naʻe, inā pono ka hoʻoheheʻe ʻana, ua ʻōlelo ʻia e hoʻomehana mua i ka mea i 260°C (500°F) a hana i kahi hana hoʻoheheʻe ma hope o ka hoʻoheheʻe ʻana ma 732-760°C (1350-1400°F) no 6 mau hola, a ukali ʻia e ka hoʻoluʻu lohi o ka umu e pale aku i ka haki ʻana. No ka hōʻoia ʻana i nā waiwai mechanical like i loko o ka hoʻoheheʻe ʻana e like me ke metala kumu, pono e hoʻohana ʻia nā mea hoʻopau hoʻoheheʻe me ke ʻano like. Ma kekahi ʻaoʻao, hiki ke noʻonoʻo ʻia ʻo AWS E/ER309 ma ke ʻano he koho kūpono.
ʻO kā mākou mau mea kūʻai aku
Nā Manaʻo Mai Kā Mākou Mea Kūʻai Aku
He nui nā pono koʻikoʻi o nā koʻokoʻo kila kila 400 series, e lilo ai lākou i mea makemake ʻia i nā noi like ʻole. Hōʻike pinepine nā koʻokoʻo kila kila 400 series i ke kūpaʻa maikaʻi loa i ka palaho, e kūʻē ana i ka oxidation, nā waikawa, nā paʻakai, a me nā mea ʻino ʻē aʻe, kūpono no nā ʻano ʻino. Hoʻohana pinepine ʻia kēia mau koʻokoʻo kila kila, e hōʻike ana i ka machinability maikaʻi loa. Maʻalahi kēia hiʻohiʻona e ʻoki, hoʻohālike, a hana. Hana maikaʻi nā koʻokoʻo kila kila 400 series i ka ikaika a me ka paʻakikī, kūpono no nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu, e like me ka hana ʻana o nā ʻāpana mechanical.
Hoʻopili ʻana:
1. He mea nui loa ka hoʻopili ʻana, ʻoiai hoʻi i nā ukana o ka honua kahi e hele ai nā ukana ma nā ʻano like ʻole e hiki ai i kahi i manaʻo nui ʻia, no laila ke kau nei mākou i ka manaʻo nui e pili ana i ka hoʻopili ʻana.
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,
