Inkcazelo emfutshane:
I-ASTM A490 A490M Iibholithi zoLwakhiwo zeHeavy Heavy Iibholithi zenzelwe ukusetyenziswa kuqhagamshelo lwesakhiwo. Olu qhagamshelo lugutyungelwe phantsi kweemfuno zeNgcaciso yeZidibaniselwano zeZakhiwo eziSebenzisa iiBholithi ze-ASTM A490, ezivunywe liBhunga loPhando ngoQhagamshelwano loLwakhiwo, elivunywe liZiko laseMelika lezoLwakhiwo lweNtsimbi kunye ne-Industrial Fastener Institute. Ubungakanani: ASME B18.2.6, ASME/ANSI B18.2.3.7M I-intshi Ubungakanani: 1/2″-1.1/2″ ezinobude obahlukeneyo Ubungakanani beMetric: M12-...

I-ASTM A490
Phambi kokurhoxa kwayo ngo-2016, iinkcukacha ze-ASTM A490 zagqunywa ukucima kunye nobushushu, intsimbi yealloyi, iibholiti zesakhiwo esinzima se-hex ukusuka kwi-1/2 ″ ububanzi nge-1-1/2 ″ ubuncinci obune-150 ksi tensile. Ezi bholithi zenzelwe ukusetyenziswa kuqhagamshelo lwesakhiwo kwaye ke ngoko zinobude obufutshane bomsonto kuneebholiti ze-hex eziqhelekileyo. Jonga kwi-Structural Bolts iphepha lendawo yethu malunga nobude bentambo kunye neminye imilinganiselo ehambelana nayo. Iibholiti ze-A490 ziyafana ngokusetyenziswa kunye nemilinganiselo ukuya kwi-A325 enzima yeebholiti ze-hex zesakhiwo kodwa zenziwe ngentsimbi yealloyi kunentsimbi yekhabhoni ephakathi, ekhokelela kwisibophelelo samandla esiphezulu. Iinkcukacha ze-A490 zisebenza kwiibholithi zesakhiwo esinzima se-hex kuphela. Iibholiti ezinobude obuhlukeneyo bomsonto kunoba buchaziweyo kwiibholithi zesakhiwo kodwa ezineempawu ezifanayo zoomatshini, bona iSpecification A354 grade BD. Iibholiti ze-ASTM A490 aziyi kugqunywa nge-galvanizing yediphu eshushu, idiphu yomatshini, okanye i-electroplating ene-zinc ngenxa yengozi enokubakho ye-hydrogen embrittlement. I-ASTM ivume ukugquma iibholiti ze-A490 kunye ne-Zinc / Aluminium Corrosion Protective Coatings nge-ASTM F1136 yeBanga lesi-3, ngokurhweba ebizwa ngokuba yiGeomet. Uvavanyo olongezelelweyo ngohlobo lweMagnetic Particle Inspection ye-Longitudinal Discontinuities kunye ne-Transverse Cracks yimfuneko yenkcazo ye-A490.
