ʻO ke kila kila kila 1.4420 (UNS S31655), i ʻike ʻia hoʻi ʻo 316LN kila kila, he kila kila austenitic kiʻekiʻe-naikokene i hoʻolālā ʻia e hāʻawi i ka ikaika mechanical i hoʻomaikaʻi ʻia a me ke kūpaʻa maikaʻi loa i ka pala. Ke hoʻohālikelike ʻia me ka 316L maʻamau, hāʻawi ʻo S31655 i ka ikaika hua kiʻekiʻe, ke kūpaʻa i hoʻonui ʻia i ka pala o ka pitting a me ka crevice, a me ka hana maikaʻi loa i nā wahi i loaʻa ka chloride. Mālama ia i ka paʻakikī maikaʻi i nā mahana haʻahaʻa a hāʻawi i ka weldability maikaʻi loa me ka ʻole o ka pono no ka mālama wela ma hope o ka weld. Hoʻohana nui ʻia nā kila kila 1.4420 i nā ipu kaomi, nā lako hana kemika, nā hale ma waho, a me nā noi cryogenic kahi e koʻikoʻi ai ka hilinaʻi a me ke kūpaʻa.

Q1: He aha ke kila kila 1.4420?
ʻO A1: 1.4420 kahi hoʻolālā maʻamau ʻEulopa no UNS S31655, i ʻike nui ʻia ʻo 316LN kila kila. He kila kila austenitic kiʻekiʻe-naikokene ia e hāʻawi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa i ka pala i hoʻohālikelike ʻia me ka maʻamau 316L.
Q2: He aha ka ʻokoʻa ma waena o S31655 a me 316L?
A2: Loaʻa i ka S31655 (316LN) kahi ʻoi aku ka nui o ka naikokene ma mua o 316L, kahi e hoʻonui nui ai i ka ikaika o ka hua a hoʻomaikaʻi i ke kū'ē ʻana i ka pitting a me ka crevice corrosion, me ka mālama ʻana i ka weldability maikaʻi loa a me ka paʻakikī.
Q3: He kūpono anei ke kila kila 1.4420 no nā noi haʻahaʻa haʻahaʻa?
A3: ʻAe. Mālama ke kila kila 1.4420 i ka paʻa maikaʻi loa a me ke kūpaʻa mechanical ma nā mahana haʻahaʻa a me ka cryogenic, e kūpono ai no nā kīʻaha kaomi, nā lako LNG, a me nā ʻōnaehana mālama cryogenic.
Q4: He aha nā ʻano a me nā nui o ka pā kila kila 1.4420 e loaʻa ana?
A4: Loaʻa nā pā kila kila 1.4420 i nā ʻano poepoe, huinahā, a me hex. Loaʻa nā anawaena maʻamau mai 6 mm a 500 mm, me nā nui maʻamau a me nā lawelawe ʻoki-i-ka-lōʻihi e loaʻa ana ma ke noi.
Q5: Hiki ke hoʻopili ʻia ka ʻauamo kila kila 1.4420 / S31655?
A5: ʻAe. Hāʻawi ke kila kila S31655 i ka hiki ke hoʻopili maikaʻi loa me ka hoʻohana ʻana i nā ʻano hana hoʻopili maʻamau. ʻAʻole koi ʻia ka mālama wela ma hope o ka hoʻopili ʻana, inā e hahai ʻia nā kaʻina hana hoʻopili kūpono.
| No ke aha e koho ai iā SAKYSTEEL: |
Kūlana Hilinaʻi– Hana ʻia kā mākou mau kaola kila kila, nā paipu, nā ʻōwili, a me nā flanges e hoʻokō i nā kūlana honua e like me ASTM, AISI, EN, a me JIS.
Nānā Paʻa– Hoʻomaʻamaʻa ʻia kēlā me kēia huahana i ka hoʻāʻo ultrasonic, ka nānā kemika, a me ka kaohi dimensional e hōʻoia i ka hana kiʻekiʻe a me ka traceability.
Waiwai ikaika a me ka hoʻouna wikiwiki– Mālama mākou i ka waihona mau o nā huahana koʻikoʻi e kākoʻo i nā kauoha wikiwiki a me ka hoʻouna ʻana i ka honua holoʻokoʻa.
Nā Hoʻonā i Hoʻopilikino ʻia– Mai ka mālama wela a hiki i ka hoʻopau ʻana i ka ʻili, hāʻawi ʻo SAKYSTEEL i nā koho i hana kūikawā ʻia e hoʻokō i kāu mau koi kikoʻī.
Hui ʻOihana- Me nā makahiki o ka ʻike hoʻokuʻu aku, hōʻoia kā mākou hui kūʻai aku a me ke kākoʻo loea i ka kamaʻilio maʻalahi, nā ʻōlelo wikiwiki, a me ka lawelawe palapala piha.
| 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. Ka loiloi hopena
4. Ka loiloi hoʻokolokolo kemika
5. Hoʻāʻo paʻakikī
6. Hoʻāʻo pale lua
7. Hoʻāʻo komo

-
ʻO ka lawelawe ʻoki-i-ka-nui
-
Ka wili ʻana a i ʻole ka hoʻomaʻamaʻa ʻana i ka ʻili
-
ʻOki ʻana i loko o nā ʻāpana a i ʻole ka foil
-
ʻO ka ʻoki ʻana i ka laser a i ʻole ka plasma

Hoʻokipa ʻia ʻo OEM/ODM
Kākoʻo ʻo SAKY STEEL i ka ʻoki maʻamau, nā hoʻoponopono hoʻopau ʻili, a me nā lawelawe ʻoki-i-ka-laulā no nā papa nickel N7. Inā makemake ʻoe i nā papa mānoanoa a i ʻole ka pepa kini lahilahi loa, hāʻawi mākou me ka pololei.
| ʻO ka hoʻopili ʻana o SAKY STEEL: |
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,
