Ibha yensimbi ye-ASTM A638 660 engenasici
Incazelo emfushane:
I-660a ibhekisela esimweni esithile se-A286 Alloy (uns S66286), okungamandla aphezulu, izinga lokushisa eliphakeme nelokulwa nokugqwala.
Ibha yensimbi engenasici:
I-ASTM A453 Ibanga le-660 liyinsimbi yemvula ye-auntenitic auntenitic acteryless esetshenziselwa kakhulu izilinganiso zokushisa ezishisa kakhulu nezinto zokushisa zokushisa eziqinile nezinto zokubopha. Isimo se-660a sensimbi esingenasici se-A286 siyisixazululo esimisiwe, sinikeza ukulinganisela kwamandla aphezulu, ukwakheka okuhle, nokuphikiswa okuhle kakhulu kokugqwala. Lokhu kwenza kulungele izicelo ezifunwayo e-aerospace, izimoto, kanye nemikhakha yezimboni lapho izinto zokwehlukana kufanele zenze ngokuthembekile ngaphansi kwengcindezi ephezulu nezimo zokuvimbela i-oxidation kanye nokumelana nezimo ezahlukahlukene zokushisa.Imivimbo ezindaweni ezahlukahlukene ezilonakalisayo , kufaka phakathi amanzi olwandle, ama-acid athambile, ne-alkalis.
