Ibha yensimbi engagqwali ye-ASTM A638 660
Incazelo emfushane:
I-660A ibhekisela esimweni esithile se-alloy ye-A286 (UNS S66286), okuyinsimbi engagqwali enamandla aphezulu, eshisa kakhulu, futhi engagqwali.
Ibha Yensimbi Engagqwali engu-660A:
I-ASTM A453 Grade 660 iyinsimbi engagqwali ye-austenitic eqinile i-precipitation esetshenziswa kabanzi ezintweni zokubopha nokubopha ezishisa kakhulu. Isimo se-660A sensimbi engagqwali ye-A286 sixutshwe ngesisombululo, sinikeza ibhalansi yamandla aphezulu, ukwakheka okuhle, kanye nokumelana okuhle kokugqwala. Lokhu kuyenza ifanele ukusetshenziswa okudingakalayo emikhakheni yezindiza, yezimoto, kanye neyezimboni lapho izinto kufanele zisebenze ngokwethembeka ngaphansi kwezimo zokucindezeleka okuphezulu kanye nokushisa okuphezulu. Ukumelana okuhle kakhulu nokugqwala kanye nokugqwala ezindaweni ezishisa kakhulu. Ukumelana okuhle nezinhlobonhlobo zezindawo ezigqwala, kufaka phakathi amanzi olwandle, ama-asidi amnene, kanye nama-alkali.

Ibanga 660 ku-Class A/B/C/D Bar Isicelo:
I-ASTM A453/A453M ihlanganisa imininingwane yokubopha okushisa okuphezulu ngama-coefficients okunwetshwa afana nensimbi engagqwali ye-austenitic. Elinye lamabanga asetshenziswa kakhulu ama-bolts e-Grade 660. Sakha ama-bolts e-stud,amabhawodi e-hex, amabhawodi okunweba,izinduku ezinentambo, nokuningi ngokusho kwe-A453 Grade 660 kumakilasi A, B, C, kanye no-D, okuhloswe ngawo izinhlelo zokusebenza zobunjiniyela ezikhethekile.
Kungani Ukhetha Thina?
•Ungathola izinto ezifanele ngokwezidingo zakho ngentengo ephansi kakhulu.
•Siphinde sinikeze amanani okulethwa kabusha, i-FOB, i-CFR, i-CIF, kanye nomnyango nomnyango. Siphakamisa ukuthi wenze isivumelwano sokuthumela esizokonga kakhulu.
•Izinto esizihlinzekayo zingaqinisekiswa ngokuphelele, kusukela esitifiketini sokuhlola izinto ezingavuthiwe kuya esitatimendeni sokugcina sobukhulu. (Imibiko izovela ngokwesidingo)
•Siyaqinisekisa ukuthi sizophendula zingakapheli amahora angama-24 (ngokuvamile ngehora elifanayo)
•Nikeza umbiko we-SGS TUV.
•Sizinikele ngokuphelele kumakhasimende ethu. Uma kungenzeki ukuhlangabezana nezidingo zakho ngemva kokuhlola zonke izinketho, ngeke sikudukise ngokwenza izithembiso ezingamanga ezizodala ubudlelwano obuhle namakhasimende.
•Nikeza isevisi yokuma okukodwa.
Ukupakisha:
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,
