ʻOiaiʻo kāna kumukūʻai kiʻekiʻe i hoʻohālikelikeʻia i nā mea kanu lāʻau maʻamau, 2507ʻO ka hilinaʻi lōʻihi a me ka hōʻemiʻana a hōʻemi i nā koi mālama mālama pono e hōʻoia i ka hoʻopukapuka, nui loa i nā kūlana koʻikoʻi a me nā lawelawe lawelawe.
No nāʻoihana e koi ana i kahi mea e hiki ai i keʻano o ka hoʻolahaʻana, Mea hoʻohui ulu nui, a me nā wahi kūpono, 2507 ʻO nā mea kila kila Super Duplex e waiho ana i kahi koho i manaʻoʻia a hilinaʻi nuiʻia.
LangHe: ʻO ka kila kila kūponoʻole & Nā lawelawe hoʻokipa
LangHe he mea hāʻawi i hāʻawiʻia ʻO nā kila kila kiʻekiʻe kiʻekiʻe, lawelawe i nāʻoihana ma kahi e hana ai, durability, a he koʻikoʻi nā kuʻekuʻe corrosion.
Me nā mea hana holomua holomua a me kahi kūpaʻa e hana i ka hana i ka hana, LangHe Hāʻawi i ka hilinaʻi, ʻO nā mea i hanaʻoleʻia e hoʻopili i nā hopena kila e hoʻokō i nā koi noi noi nui loa.
Hoʻokomoʻia kā mākou mau mea hana kila kūpono:
- Hoʻolei kālā & Nalowale shop
ʻO ka nānāʻana kiʻekiʻe loa no nā geometries paʻakikī, e hōʻoia ana i nā mea i hoʻopaʻaʻia a me nā kiʻekiʻe kiʻekiʻe. - Sand cread & Nā wili lei
Kūpono no nā'āpana nui a me nā hana kūpono, no nā'āpanaʻoihana a me nā pae hoʻonohonoho. - CNC Mīkini & Post-ho'ōla
Hoʻopiha i nā lawelawe machining e komo pū ana, MilightʻAʻole, hoʻomālamalama, Kāleka, a me nā hana kino.
Inā makemakeʻoe i nā'āpana kiʻekiʻe, ʻO nā mea hoʻokūkū paʻakikī, a iʻole nā'āpanaʻokoʻa, LangHe ʻO kāu hoa noho hilinaʻi i loko o ka hana sweel hoʻopunipuni.
Kāhea iā mā˚ou I kēia mau lā e aʻo pehea LangHe hiki ke hāʻawi i nā hopena steelless i nā hopena i nā hana me ka hana, hilinaʻi, a me ka pololei pololei i kāu mau noi.

He aha kaʻokoʻa ma waena o ka super duplex 2205 and 2507?
ʻO kaʻokoʻa nui ka hoʻopunipuni ma kā lākou huiʻana a me ka hana: 2507 he chromium kiʻekiʻe, Mybridelu, a me nā kiʻekiʻe o ka nitrogen ma mua 2205,
hopena i ka paleʻana o ka corrosion (E kū'ē kū'ē iā Chortide Stress Corrosion Cracking) a me ka ikaika kiʻekiʻe.
2507 ua manaʻoʻia he uku keu, ʻoi aku ka kiʻekiʻe ma mua 2205.
He aha ka mea like me ka super duplex 2507?
Nā mea like me ka super duplex 2507 komo i ka UND S32750 a me Astm A240 Type 2507.
I nā hua'ōleloʻoihana, e pili ana i nā helu e like me ka saf 2507 e Sandvik, X2crnimon25-7-4 i nā kūlana, a me zero 100 I nā alloys alloys.
He aha ka saf 2507 waiwai?
Loko 2507 ʻo ia ka inoa o kaʻoihana no ka super fuplex stick 2507 Nā mea i hanaʻia e kaʻenehanaʻo Sandvik.
Loaʻa ia i ka hui like me keʻano a me nā waiwai e like me keʻano maʻamau 2507 a ua hoʻohana nuiʻia no nā noi e koi ana i ke kū'ēʻana i ke kū'ē a me ka ikaika.
