ASTM A536 Nodular Cast Iron Bar | Thupa ea Tšepe ea Spheroidal Graphite
Selelekela sa Sehlahisoa
ASTM A536 Nodular Cast Iron Bar ke thepa e entsoeng ka nepo e etselitsoeng lits'ebetso tse sebetsang hantle lits'ebetsong tsa haeteroliki le tsa likoloi. E entsoe ho latela maemo a thata a ASTM A536, tšepe ena ea spheroidal graphite (SG) e kopanya matla a tšepe le bokhoni bo phahameng ba ho lahla le ho thothomela ha tšepe. E ananeloa haholo ka lebaka la ho hanyetsa mokhathala, ho sebetsa hantle ha eona, le botsitso ba eona tlas'a khatello.
Tšepe e entsoeng ka maqhutsu, eo hape e bitsoang tšepe e ductile, e fapana le tšepe e putsoa ka hore dikahare tsa khabone di etsa maqhutsu a graphite a spheroidal ho ena le maqhutsu. Phapang ena ya sebopeho e e fa matla a ho kgwehla a hodimo haholo mme e fana ka matla, e leng se etsang hore e be thepa e tshepahalang bakeng sa dibaka tse jarang mojaro le tse nang le kgatello e phahameng.
- lithapo tsa tšepe tse entsoeng ka ductile li etsoa ho latela maemo a machaba. Lithapo tsa tšepe tse sebelisoang hangata tsa lithapo tsa tšepe tse entsoeng ka ductile li hlahisoa ka litsela tse fapaneng ho latela linaha le maemo a fapaneng.
Tse latelang ke limaraka tsa tšepe tsa ductile tse sebelisoang haholo (limaraka) tlas'a litsamaiso tse 'maloa tse tloaelehileng tse tloaelehileng:
