| No ke aha e koho ai iā mākou: |
1. Hiki iā ʻoe ke loaʻa ka mea kūpono e like me kāu koi ma ka liʻiliʻi loa o ke kumu kūʻai.
2. Hāʻawi pū mākou i nā Reworks, FOB, CFR, CIF, a me nā kumukūʻai hoʻopuka puka. Manaʻo mākou iā ʻoe e hana i ka hana no ka hoʻouna ʻana e ʻoi aku ka waiwai.
3. ʻO nā mea a mākou e hāʻawi nei ua hiki ke hōʻoia ʻia, mai ka palapala hōʻike maka a hiki i ka ʻōlelo kikoʻī hope loa. (E hōʻike ʻia nā hōʻike ma ke koi)
4. e hōʻoiaʻiʻo e hāʻawi i ka pane i loko o 24hours (maʻamau i ka hola hoʻokahi)
5. Hiki iā ʻoe ke kiʻi i nā mea kūʻai ʻokoʻa, nā hāʻawi wili me ka hōʻemi ʻana i ka manawa hana.
6. Hoʻolaʻa piha mākou i kā mākou mea kūʻai. 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 mea kūʻai aku.
| ʻO SAKY STEEL'S Quality Assurance (me nā mea luku a me ka non-destructive): |
1. Ho'āʻo ʻana i ke ana ʻike
2. Mechanical nānā 'ana e like me tensile, Elongation a me ka ho'ēmi 'āpana.
3. Ka nānā 'ana i ka hopena
4. Ka nānā 'ana i ka ho'ā'o kemika
5. Hoao paakiki
6. Ho'āʻo pale lua
7. Hoao Penetrant
8. Intergranular Corrosion Ho'āʻo
9. Ho'āʻo Roughness
10. Ho'āʻo hoʻokolohua Metallography
| ʻO SAKY STEEL'S Packaging: |
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,
ʻO ka 253Ma alloy nā hiʻohiʻona penei:
ʻO 253MA kahi kila austenitic kūpaʻa wela i hoʻolālā ʻia no nā noi e koi ana i ka ikaika creep kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion maikaʻi. ʻO 850 ~ 1100 °C kāna hana wela.
ʻO ka hui kemika o 253MA he kaulike, kahi e loaʻa ai i ke kila nā waiwai piha kūpono i ka pae wela o 850 °C-1100 °C, kiʻekiʻe kiʻekiʻe oxidation kū'ē, a hiki i ka 1150 °C; kiʻekiʻe kiʻekiʻe kiʻekiʻe kolo ʻana Ka hiki a me ka ikaika o ka haki ʻana; maikaʻi ke kū'ē i ka wela wela a me ke kū'ēʻana i ka palahū i ka nui o nā media kinoea; ka ikaika kiʻekiʻe a me ka ikaika tensile i nā wela kiʻekiʻe; maikaʻi formability a weldability A lawa machinability.
Ma waho aʻe o nā mea hoʻohui i ka chromium a me ka nickel, 253MA stainless steel pū kekahi me ka liʻiliʻi o ka metala honua laha loa (Rare Earth Metals, REM), kahi e hoʻomaikaʻi nui ai i kona mana antioxidant. Hoʻohui ʻia ka Nitrogen e hoʻomaikaʻi i nā waiwai kolo a hana i kēia kila i austenite piha. ʻOiai he haʻahaʻa ka chromium a me ka nickel ma loko, ʻo kēia kila kuhili ka nui o nā hiʻohiʻona wela kiʻekiʻe e like me ke kila kila kiʻekiʻe a me ka nickel-based alloy.
Nā noi 253Ma:
Hoʻohana nui ʻia ʻo 253MA i nā lako sintering, nā mea hoʻoheheʻe ahi, ka hoʻoheheʻe ʻana i ke kila, ka umu a me nā mea hoʻolei hoʻomau, nā wili wili (nā umu wela), nā kapuahi hoʻomaʻamaʻa wela a me nā mea pono, nā mea minerala a me nā lako hana sima.
