ASTM A490
Kahor ka bixitaankeeda sanadka 2016, qeexida ASTM A490 waxay dabooshay damiyay oo dabcay, bir daawaha ah, boolal qaabdhismeedka hex culus oo ka yimid 1/2 ″ dhexroor ilaa 1-1/2 ″ dhexroor leh ugu yaraan 150 ksi tensile. Dhalooyinkan waxaa loogu talagalay in loogu isticmaalo isku xirka qaabdhismeedka sidaas darteed waxay leeyihiin dhererka dunta ka gaaban kuwa caadiga ah. Ka eeg bogga Bolts-dhismeedka boggayaga dhererka dunta iyo cabbirrada kale ee la xidhiidha. bolts A490 waxay la mid yihiin codsiga iyo cabbirada A325 xargaha qaab dhismeedka hex culus laakiin waxay ka samaysan yihiin birta daawaha ah halkii ay ka ahaan lahaayeen birta kaarboonka dhexdhexaadka ah, taas oo keeneysa xire xoog sare leh. Tilmaamaha A490 waxa lagu dabaqi karaa boolal-dhismeed hex culus oo keliya. Daboolka leh dhererka dunta ka duwan ee lagu cayimay boolal-dhismeed laakiin leh sifooyin farsamo oo la mid ah, eeg Tilmaamaha A354 darajada BD. bolts ASTM A490 laguma dahaadhayso galvanizing-kulul, meel dhigis makaanik ah, ama koronto ku shubasho zinc sababtoo ah khatarta suurtagalka ah ee burburinta hydrogen. ASTM waxay ogolaatay daahan A490 boolal leh Zinc/Aluminium Corrosion Coatings Ka ilaalinta halkii ASTM F1136 Fasalka 3, ganacsi ahaan loo yaqaan Geomet. Tijaabooyin dheeri ah oo ah qaabka Baaritaanka Qaybaha Magnetic-ka ee Joojinta Dheeraadka ah iyo Dildilaaca Kala-guurka waa shuruudda qeexitaanka A490.
