1. Ungathola izinto ezifanele ngokwesidingo sakho ngentengo ephansi kakhulu.
2. Siphinde sinikeze amanani okulethwa kabusha, i-FOB, i-CFR, i-CIF, kanye nomnyango nomnyango. Siphakamisa ukuthi wenze isivumelwano sokuthumela esizokonga kakhulu.
3. Izinto esizihlinzekayo zingaqinisekiswa ngokuphelele, kusukela esitifiketini sokuhlola izinto ezingavuthiwe kuya esitatimendeni sokugcina sobukhulu. (Imibiko izovela ngokwesidingo)
4. Siqinisekisa ukunikeza impendulo zingakapheli amahora angama-24 (ngokuvamile ngehora elifanayo)
5. Ungathola ezinye izindlela zesitoko, ukulethwa kwemishini ngokunciphisa isikhathi sokukhiqiza.
6. Sizinikele ngokuphelele kumakhasimende ethu. Uma kungenzeki ukuhlangabezana nezidingo zakho ngemva kokuhlola zonke izinketho, ngeke sikudukise ngokwenza izithembiso ezingamanga ezizodala ubudlelwano obuhle namakhasimende.

9. Ukuhlolwa Kokuhluzeka
10. Ukuhlolwa Kokuhlola Kwe-Metallography
| Ukupakisha kwe-SAKY STEEL'S: |
1. Ukupakisha kubaluleke kakhulu ikakhulukazi uma kuthunyelwa kwamanye amazwe lapho imithwalo idlula khona ngemigudu eyahlukene ukuze ifike endaweni yokugcina, ngakho-ke sikhathalela kakhulu ukupakisha.
2. I-Saky Steel ipakisha izimpahla zethu ngezindlela eziningi ngokusekelwe emikhiqizweni. Sipakisha imikhiqizo yethu ngezindlela eziningi, njengokuthi,
I-alloy engu-253Ma inezici ezilandelayo:
I-253MA iyinsimbi engagqwali ye-austenitic engagqwali engamelana nokushisa eyenzelwe izinhlelo zokusebenza ezidinga amandla aphezulu okukhukhuleka kanye nokumelana okuhle nokugqwala. Izinga layo lokushisa lokusebenza lingu-850~1100 °C.
Ukwakheka kwamakhemikhali kwe-253MA kuyalinganisela, okwenza insimbi ibe nezakhiwo ezifanele kakhulu eziphelele ebangeni lokushisa elingu-850 °C-1100 °C, ukumelana okuphezulu kakhulu kwe-oxidation, kanye nokushisa kwesikali kufikela ku-1150 °C; ukumelana okuphezulu kakhulu kwe-creep Amandla kanye namandla okuqhekeka kwe-creep; ukumelana okuhle kokugqwala kokushisa okuphezulu kanye nokumelana nokugqwala kwebhulashi ezindaweni eziningi zegesi; amandla aphezulu okukhiqiza kanye namandla okudonsa emazingeni okushisa aphezulu; ukwakheka okuhle kanye nokushibilika kanye nokusebenza okwanele komshini.
Ngaphezu kwezinto ezihlanganisa i-chromium ne-nickel, insimbi engagqwali engu-253MA iqukethe nenani elincane lensimbi engagqwali yomhlaba (i-Rare Earth Metals, i-REM), ethuthukisa kakhulu amandla ayo okulwa ne-antioxidant. I-nitrogen iyengezwa ukuthuthukisa izakhiwo zokuqhekeka nokwenza le nsimbi ibe yi-austenite ephelele. Nakuba okuqukethwe yi-chromium ne-nickel kuphansi kakhulu, le nsimbi engagqwali inezici eziningi zokushisa okuphezulu ezifana nensimbi engagqwali exutshwe kakhulu kanye ne-nickel-based alloy.
Izinhlelo zokusebenza ze-253Ma:
I-253MA isetshenziswa kabanzi emishinini yokusinta, imishini yesithando somlilo esiqhumayo, ukuncibilikisa insimbi, imishini yesithando somlilo kanye nokusatshalaliswa okuqhubekayo, imishini yokugoqa (izithando zokushisa), izithando zokushisa kanye nezesekeli, imishini yamaminerali kanye nemishini yokukhiqiza usimende.
