| He aha i whiriwhiri ai mātou: |
1. Ka taea e koe te tiki i te rauemi tino tika e ai ki ō hiahia i te utu iti rawa.
2. Kei a mātou anō ngā utu tuku Reworks, FOB, CFR, CIF, me te tatau ki te tatau. Ka tūtohu mātou kia mahi koe i tētahi kirimana utu iti mō te tuku, ā, he tino ohanga tēnei.
3. Ka taea te manatoko i ngā rauemi e tukuna ana e mātou, mai i te tiwhikete whakamātautau rauemi mata ki te tauākī whakamutunga mō ngā āhuatanga. (Ka whakaatuhia ngā pūrongo mēnā e hiahiatia ana)
4. te taurangi ki te tuku whakautu i roto i ngā haora 24 (i taua haora anō)
5. Ka taea e koe te tiki i ētahi atu momo taonga, ngā tuku mira me te whakaiti i te wā hanga.
6. E tino whakapau kaha ana mātou ki te tautoko i ā mātou kiritaki. Mēnā kāore e taea te whakatutuki i ō hiahia i muri i te tirotiro i ngā kōwhiringa katoa, e kore mātou e tinihanga i a koe mā te whakaputa kupu whakaari teka, ka waihanga hononga pai ki ngā kiritaki.

| Ngā Tākai a SAKY STEEL: |
1. He mea nui te tākai, inā koa mō ngā tukunga o tāwāhi e haere ana ngā uta mā roto i ngā huarahi rerekē kia tae atu ki te ūnga whakamutunga, nō reira ka tino aro nui mātou ki te tākai.
2. He maha ngā huarahi e tākai ai a Saky Steel i ā mātou taonga, e ai ki ngā hua. He maha ngā huarahi e tākai ai mātou i ā mātou hua, pērā i,
Ko ngā āhuatanga o te koranu 253Ma e whai ake nei:
He kowiri tira austenitic ātete-wera te 253MA, ā, he mea hanga mō ngā mahi e hiahia ana kia kaha te ngoki me te ātete pai ki te waikura. Ko tōna awhe pāmahana mahi he 850~1100 °C.
He taurite te hanganga matū o te 253MA, ā, he pai rawa ngā āhuatanga whānui o te maitai i waenga i te 850 °C ki te 1100 °C, he tino teitei te ātete ki te waikura, ā, ko te pāmahana tauine tae atu ki te 1150 °C; he tino teitei te ātete ngokingoki, te kaha me te kaha pakaru ngokingoki; he pai te ātete ki te waikura pāmahana teitei me te ātete ki te waikura paraihe i roto i te nuinga o ngā pāpāho hau; he teitei te kaha hua me te kaha kume i ngā pāmahana teitei; he pai te āhua me te kaha whakarewa, ā, he nui te kaha miihini.
Haunga ngā huānga whakarewa chromium me te nickel, kei roto hoki i te maitai kore waikura 253MA he iti noa te konganuku whenua onge (Rare Earth Metals, REM), e whakapai ake ana i tōna kaha ārai mate. Ka tāpirihia te hauota hei whakapai ake i ngā āhuatanga ngoki me te hanga i tēnei maitai hei austenite tino. Ahakoa he iti noa te ihirangi chromium me te nickel, he maha ngā āhuatanga pāmahana teitei o tēnei maitai kore waikura ki te maitai koranu whakarewa teitei me te koranu nickel-based.
Ngā tono 253Ma:
E whakamahia whānuitia ana te 253MA i roto i ngā taputapu whakawera, ngā taputapu oumu pupuhi, te whakarewa maitai, ngā taputapu oumu me te whakarewa tonu, ngā mira hurihuri (ngā oumu whakamahana), ngā oumu me ngā taputapu maimoatanga wera, ngā taputapu kohuke me ngā taputapu whakaputa sima.
