420 Pālahalaha Kila Kila
Wehewehe Pōkole:
Nā Pā Pālahalaha Din 1.4034 SS 430, SS UNS S42000 Pā Pālahalaha, Pā Pālahalaha Kila Kila 420, Nā Pā Kila Kila Anu 420 i hoʻolako ʻia ma Kina.
ʻO ke kila kila kila papa 420 he kila kalapona kiʻekiʻe me ka liʻiliʻi o ka chromium o 12%. E like me nā kila kila ʻē aʻe, hiki ke hoʻopaʻakikī ʻia ka papa 420 ma o ka mālama wela. Hāʻawi ia i ka ductility maikaʻi i kona kūlana annealed a me nā waiwai kūpaʻa corrosion maikaʻi loa ke hoʻopili ʻia ka metala, hoʻoheheʻe ʻia ka ʻili a paʻakikī paha. ʻO kēia papa ka paʻakikī kiʻekiʻe loa - 50HRC - ma waena o nā papa kila kila āpau me 12% chromium.

| ʻO ka hōʻoia maikaʻi o SAKY STEEL (me nā mea luku a me nā mea luku ʻole): |
1. Hoʻāʻo Ana ʻIke
2. Ka nānā ʻana i ka mīkini e like me ka tensile, Elongation a me ka hōʻemi ʻana o ka wahi.
3. Hoʻāʻo Ultrasonic
4. Ka loiloi hoʻokolokolo kemika
5. Hoʻāʻo paʻakikī
6. Hoʻāʻo pale lua
7. Hoʻāʻo komo
8. Hoʻāʻo ʻana i ka palaho Intergranular
9. Ka loiloi hopena
10. Hoʻāʻo Hoʻokolohua Metallography

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,
Nā noi:
ʻO nā noi e koi ana i ke kūpaʻa ʻana i ka palaho kūpono a me nā waiwai mechanical kiʻekiʻe he kūpono ia no Alloy 420. ʻO nā hiʻohiʻona o nā noi i hoʻohana pinepine ʻia me Alloy 420:
Nā mea ʻokiʻoki
Nā pahi turbine mahu a me ke kinoea
Nā lako kīhini
Nā ʻūmiʻi, nā nati, nā wili
Nā ʻāpana a me nā ʻau o ka pamu a me ka valve
Nā moena alapiʻi o kaʻu
Nā mea hana niho a me ke ʻoki kino
Nā Nozzles
Nā pōpō kila paʻakikī a me nā noho no nā pamu luawai aila
