I-ASTM A490
Ngaphambi kokuhoxiswa kwayo ngo-2016, ukucaciswa kwe-ASTM A490 kwakumbozwa insimbi ecishiwe futhi eqinile, ingxubevange, amabhawodi asindayo esakhiwo se-hex ukusuka ku-1/2″ ububanzi kuya ku-1-1/2″ anobuncane be-150 ksi tensile. Lawa mabhawodi enzelwe ukusetshenziswa ekuxhumekeni kwesakhiwo futhi ngenxa yalokho anobude bentambo emifushane kunamabhawodi e-hex ajwayelekile. Bheka ekhasini le-Structural Bolts lesayithi lethu ukuze uthole ubude bentambo nobunye ubukhulu obuhlobene. Amabhawodi e-A490 afana ngokusebenza kanye nobukhulu bamabhawodi esakhiwo esindayo se-hex angu-A325 kodwa enziwe ngensimbi eyingxubevange kunensimbi ye-carbon steel emaphakathi, okuholela esibopheni samandla esiphezulu. Ukucaciswa kwe-A490 kusebenza kumabhawodi asindayo wesakhiwo se-hex kuphela. Ukuze uthole amabhawudi anobude obuhlukene bomucu kunalowo ashiwo kumabhawodi esakhiwo kodwa anezici ezifanayo zomshini, bheka i-Specification A354 grade BD. Amabhawodi e-ASTM A490 akufanele ambozwe ngokufaka ugesi oshisayo, ukufakwa ngomshini, noma i-electroplating ene-zinc ngenxa yengozi engaba khona ye-hydrogen embrittlement. I-ASTM igunyaze ukumboza amabhawodi angu-A490 aneZinc/Aluminium Corrosion Protective Coatings nge-ASTM F1136 Grade 3, ngokwentengiso ebizwa ngokuthi i-Geomet. Ukuhlola okwengeziwe ngendlela ye-Magnetic Particle Inspection ye-Longitudinal Discontinuities kanye nama-Transverse Cracks kuyisidingo sokucaciswa kwe-A490.
