ASTM A490

Pele e tlosoa ka selemo sa 2016, sebopeho sa ASTM A490 se ne se koaheloa ka tšepe e tiileng le e halefileng, tšepe ea alloy, liboutu tse boima tsa hex ho tloha bophara ba 1/2 ″ ho isa bophara ba 1-1 / 2 ″ ka bonyane ba 150 ksi tensile. Liboutu tsena li reretsoe ho sebelisoa likhokahanong tsa meralo, ka hona li na le bolelele ba likhoele tse khuts'oane ho feta liboutu tse tloaelehileng tsa hex. Sheba leqephe la Structural Bolts sebakeng sa rona bakeng sa bolelele ba likhoele le litekanyo tse ling tse amanang. Liboutu tsa A490 li ts'oana ka ts'ebeliso le boholo ho liboutu tsa sebopeho sa hex tse boima tsa A325 empa li entsoe ka tšepe ea alloy ho fapana le tšepe ea khabone e mahareng, e bakang sehokelo sa matla se phahameng. Tlhaloso ea A490 e sebetsa ho liboutu tse boima tsa hex feela. Bakeng sa liboutu tse nang le bolelele ba likhoele tse fapaneng ho feta tse boletsoeng bakeng sa liboutu tsa meralo empa tse nang le thepa e tšoanang ea mochini, bona Specification A354 grade BD. Liboutu tsa ASTM A490 ha lia lokela ho koaheloa ka galvanizing ea hot-dip, mechanical deposition, kapa electroplating e nang le zinki ka lebaka la kotsi e ka bang teng ea hydrogen embrittlement. ASTM e amohetse liboutu tsa A490 tse nang le Zinc/Aluminium Corrosion Protective Coatings ka ASTM F1136 Grade 3, e bitsoang Geomet khoebong.
