Ibha yentsimbi engagqwaliyo ye-ASTM A638 660
Inkcazo emfutshane:
I-660A ibhekisa kwimeko ethile ye-A286 alloy (UNS S66286), eyintsimbi engagqwali enamandla aphezulu, eshushu kakhulu, kwaye enganyangekiyo kukugqwala.
Ibha yentsimbi engagqwaliyo ye-660A:
I-ASTM A453 Grade 660 yintsimbi engagqwaliyo ye-austenitic eqina imvula esetyenziswa kakhulu kwizinto zokubopha nokubopha ngobushushu obuphezulu. Imeko ye-660A yentsimbi engagqwali ye-A286 inyibilikisiwe ngesisombululo, inika ulungelelwano lwamandla aphezulu, ukwakheka okuhle, kunye nokumelana nokugqwala okugqwesileyo. Oku kuyenza ifaneleke kwizicelo ezifunekayo kwiindawo zeenqwelo moya, iimoto, kunye nemizi-mveliso apho izixhobo kufuneka zisebenze ngokuthembekileyo phantsi kweemeko zoxinzelelo oluphezulu kunye nobushushu obuphezulu. Ukumelana okuhle kakhulu ne-oxidation kunye nokugqwala kwiindawo zobushushu obuphezulu. Ukumelana okuhle kwiindawo ezahlukeneyo zokugqwala, kubandakanya amanzi olwandle, ii-asidi ezithambileyo, kunye ne-alkalis.
