ASTM A 490 Cov Lus Qhia Tshwj Xeeb

Ua ntej nws tshem tawm hauv 2016, ASTM A490 specification npog quenched thiab tempered, hlau alloy, hnyav hex structural bolts los ntawm 1/2 "txoj kab uas hla mus txog 1-1/2" txoj kab uas hla nrog tsawg kawg yog 150 ksi tensile. Cov bolts no yog tsim los siv rau hauv cov qauv kev sib txuas thiab yog li ntawd muaj cov xov luv luv dua li cov qauv hex bolts. Xa mus rau nplooj ntawv Tus Qauv Bolts ntawm peb qhov chaw rau cov xov ntev thiab lwm qhov ntev. A490 bolts zoo ib yam hauv daim ntawv thov thiab qhov ntev rau A325 hnyav hex qauv bolts tab sis yog tsim los ntawm cov hlau alloy es tsis yog cov pa roj carbon steel, uas ua rau muaj zog dua fastener. A490 specification yog siv rau hnyav hex qauv bolts nkaus xwb. Rau bolts nrog cov xov sib txawv ntev dua li teev rau cov qauv bolts tab sis nrog cov khoom zoo sib xws, saib Specification A354 qib BD. ASTM A490 bolts yuav tsum tsis txhob coated los ntawm kub-dip galvanizing, mechanical deposition, los yog electroplating nrog zinc vim muaj peev xwm ntawm hydrogen embrittlement. ASTM tau pom zoo txheej A490 bolts nrog Zinc / Aluminium Corrosion Protective Coatings rau ASTM F1136 Qib 3, kev lag luam hu ua Geomet. Kev ntsuam xyuas ntxiv hauv daim ntawv ntawm Kev Tshawb Fawb Sib Nqus Particle rau Longitudinal Discontinuities thiab Transverse Cracks yog qhov yuav tsum tau ua ntawm A490 specification.
