Miyala Yozungulira ya ASTM A572 vs ASTM A992: Kusiyana Kofunika, Kuyerekeza Mphamvu & Kusankha Kwabwino Kwambiri

M'nyumba za nyumba zamakono zachitsulo,Miyendo ya Wntchito yake ngati gawo lalikulu lolimbana ndi katundu wa chimango, chomwe kusankha zinthu kumakhudza kwambiri chitetezo komanso mtengo wa nyumbayo. Kodi kusiyana kwakukulu pakati pa miyezo iwiri yotchuka kwambiri pamsika pakadali pano ndi kotani -ASTM A572 Giredi 50ndiASTM A992Antchito aukadaulo a Royal Steel ndi omwe amatanthauzira bwino.

A992: Muyezo wamakampani wopangidwira makamaka injini "zotambalala"

A572 Giredi 50, ngakhale kuti ndi yotchuka mumakampani opanga zitsulo, ASTM A992 ndiye 'muyezo wagolide' waMatabwa a Wlero.

Kusiyanitsa kwa Press ndi Mtundu wa Zamalonda: A572 ndi muyezo wamba wa mbale, mipiringidzo ndi ma profiles ena koma A992 ndi imodzi ya ma bearing a wide-flange ozungulira ndi hot-rolled.

Kukonza Mankhwala: A992 ndi yolimba kwambiri pankhani ya kapangidwe ka mankhwala, zomwe zimapangitsa kuti chitsulo chikhale chapamwamba kwambiri kudzera mu kuwonjezera zinthu zotsalira (vanadium, niobium, copper ndi nickel).

Kuyerekeza magwiridwe antchito apakati: Nchifukwa chiyani A992 ikusintha pang'onopang'ono A572?

Mu kapangidwe ka kapangidwe kake, A992 ikuwonetsa zabwino zazikulu:

Kulamulira Chiŵerengero Chogwirizana ndi Kulimba: A992 imatchula chiŵerengero chachikulu cha mphamvu yogwira ntchito yosapitirira 0.85. Kusinthasintha kwabwino kumeneku kumapangitsa kuti ikhale yabwino kwambiri m'nyumba zomwe zimakhudzidwa ndi zivomerezi, zomwe zimathandiza kuti mphamvu zilowe bwino.

Kutha kupotokaChifukwa cha malire okhwima a A992 pa carbon equivalent, kuthekera kwake kusinthasintha kwa nthaka kumakhala kokhazikika kuposa A572, zomwe zimachepetsa chiopsezo cha ming'alu ya weld.

Kusasinthasintha kwa Mphamvu: A992 imatchula mphamvu yocheperako ya 50 ksi (pafupifupi 345 MPa) ndipo imayika malire a mphamvu yokwanira ya 50 ksi, kuonetsetsa kuti pali kuneneratu kolondola kwa kupsinjika panthawi yokonza kapangidwe kake.

Kupereka kwa msika ndi satifiketi ziwiri

Monga kampani yotsogola padziko lonse yogulitsa zitsulo, Royal Steel yawona zotsatirazi mu ntchito zake zotumiza kunja:

Muyezo Wokhazikika: M'misika yapamwamba kwambiri ya zipangizo zomangira ku North America ndi Latin America,Chitsulo chachikulu cha Flangenthawi zambiri imaonedwa kuti ndi A992.

Chitsimikizo Chachiwiri: Chitsulo cha A992 chapamwamba kwambiri chomwe chili pamsika chimakwaniritsanso zofunikira za A572 Giredi 50. Izi zikutanthauza kuti makasitomala omwe amagula A992 nthawi zambiri amakhala ndi zinthu zakuthupi zabwino kwambiri poyerekeza ndi A572.

Malangizo a Royal Steel

"Mukasankhamatayala akuluakulu a flange, ngati ntchito yanu ikuphatikizapo kuwotcherera zinthu zovuta kapena ili pamalo omwe chivomezi chimatha kuchitika, A992 ndiye chisankho choyamba chotsimikizika,” anatero mkulu wa Dipatimenti Yogulitsa Zapadziko Lonse ya Royal Steel.

Pakadali pano,Chitsulo Chachifumu cha Chinaimasunga matani masauzande ambiri a A992 ndi A572 m'masitolo m'madoko monga Tianjin, Qingdao, ndi Shanghai. Ndi zaka 12 zakuchitikira mu kutumiza zitsulo kunja, sitimangopereka zinthu zapamwamba zomwe zimakwaniritsa miyezo ya US ASTM, komanso timapereka chithandizo chaukadaulo chosinthidwa malinga ndi zosowa za makasitomala athu.
