ASTM A490 A490M Kaumaha Hex Structural Bolt
ʻO ka wehewehe pōkole:
ASTM A490 A490M Heavy Hex Structural Bolts Ua manaʻo ʻia nā bolts no ka hoʻohana ʻana i nā pilina pili. Hoʻopiliʻia kēia mau pilina ma lalo o nā koi o ka Specification for Structural Joints Using ASTM A490 Bolts, i'āponoʻia e ka Research Council on Structural Connections, i kākoʻoʻia e ka American Institute of Steel Construction a me ka Industrial Fastener Institute.

ASTM A490
Ma mua o kona hoʻihoʻi ʻana i ka makahiki 2016, ua uhi ʻia ka kikoʻī ASTM A490 i hoʻopaʻa ʻia a hoʻopaʻa ʻia, ke kila kila, nā bolts structural hex kaumaha mai 1/2 ″ anawaena a hiki i 1-1/2 ″ anawaena me ka liʻiliʻi 150 ksi tensile. Hoʻohana ʻia kēia mau bolts no ka hoʻohana ʻana i nā pilina kūkulu ʻia a no laila ʻoi aku ka lōʻihi o ka lōʻihi o ke kaula ma mua o nā bolts hex maʻamau. E nānā i ka ʻaoʻao Structural Bolts o kā mākou pūnaewele no ka lōʻihi o ke kaula a me nā ana e pili ana. Ua like nā bolts A490 i ka noi a me nā ana me A325 heavy hex structural bolts akā ua hana ʻia mai ke kila kila ma mua o ke kila kalapona waena, e loaʻa ana i kahi paʻa ikaika kiʻekiʻe. Hoʻopili ʻia ka ʻōlelo kikoʻī A490 i nā bolts structural hex kaumaha wale nō. No nā kī me nā lōʻihi like ʻole ma mua o ka mea i kuhikuhi ʻia no nā bolts i kūkulu ʻia akā me nā ʻano mekini like, e ʻike i ka kikoʻī A354 grade BD. ʻAʻole e uhi ʻia nā bolts ASTM A490 e ka wela-dip galvanizing, mechanical deposition, a i ʻole electroplating me ka zinc ma muli o ka pilikia o ka hydrogen embrittlement. Ua ʻae ʻo ASTM i ka uhi ʻana i nā bolts A490 me Zinc/Aluminium Corrosion Protective Coatings no ASTM F1136 Grade 3, i kapa ʻia ʻo Geomet. ʻO ka hoʻāʻo hou ʻana ma ke ʻano o Magnetic Particle Inspection for Longitudinal Discontinuities and Transverse Cracks kahi koi o ka kikoʻī A490.
