Cov yam ntxwv ntawm cov khoom
A325 Heavy Hex Bolts
Crafted los ntawm cov pa roj carbon los yog qis- alloy steel, cov bolts no muaj lub taub hau hexagonal, ib feem xov tsim, thiab feem ntau ua tiav nrog kub -dip galvanizing lossis dub oxide. Kev khav theeb muaj zog, lawv yog cov kev xaiv zoo tshaj plaws rau cov qauv tsim steel qauv kev sib txuas, ntsuas kev ua tau zoo thiab tus nqi- ua tau zoo.
A490 Hnyav Hex Bolts
Ua los ntawm nruab nrab- carbon alloy steel, cov bolts no muaj lub zog ultra- siab zog nrog lub taub hau hexagonal, ib feem xov, thiab cov xim dub oxide tiav. Engineered rau hnyav-load thiab siab-xav tau steel qauv kev sib txuas, lawv ua tau zoo nyob rau hauv cov xwm txheej uas xav tau kev ua haujlwm zoo tshaj plaws thiab cov qauv kev ruaj ntseg.
Daim ntawv thov teb
A325
Qhov zoo tshaj plaws rau kev tsim vaj tsev dav dav, txuas hniav, kev sib txuas lus pej thuam, kev cob qhia kev lag luam, warehouses, thiab lwm yam steel qauv tej yaam num nrog cov txheej txheem load.
A490
Haum rau siab -xav tau scenarios nrog rau ntev- ncua steel qauv, hnyav- lub luag hauj lwm machinery, lifting khoom, nuclear fais fab nroj tsuag, siab- nce tsev, thiab lwm yam dej num uas yuav tsum tau tshwj xeeb load- bearing muaj peev xwm thiab kev ruaj ntseg redundancy.
Kev siv ceev faj
Kev teeb tsa:
Siv lub torque ciaj ntswj kom nruj hauv ob theem ntawm tus nqi tsim torque. Tsis txhob dhau- zawm (uas yuav ua rau cov xov los yog cov hlua khi) puas los yog hauv qab - zawm (uas ua rau muaj kev pheej hmoo ntawm kev xoob).
Environmental Adaptation:
Kub-dip galvanizing raug pom zoo rau qhov chaw ntub lossis sab nraum zoov los txhim kho corrosion. Rau ib puag ncig marine nrog cov tshuaj chloride siab, tshwj xeeb los tiv thaiv- kev kho corrosion yog yuav tsum tau.
Kev tu:
Ua kev soj ntsuam tsis tu ncua. Tam sim ntawd hloov bolts yog tias pom tias xoob, corrosion, xov puas, lossis cov khoom qaug zog raug kuaj pom.
Tseem ceeb Taboos:
Rov qab siv A325 / A490 bolts yog nruj me ntsis txwv tsis pub tom qab disassembly, vim kev qaug zog puas tuaj yeem cuam tshuam cov qauv kev nyab xeeb. Tsis txhob sib tov bolts ntawm qib sib txawv, cov ntaub ntawv, lossis cov lus qhia tshwj xeeb hauv tib qho kev sib txuas.

FAQ: Qhov txawv ntawm A325 / A490 thiab Standard Hex Bolts
Cov kev sib txawv tseem ceeb nyob hauv qib zog, cov khoom siv & cov txheej txheem tsim khoom, daim ntawv thov scenarios, thiab kev siv tshwj xeeb:
Strength Qib & Mechanical Performance:
Standard hex bolts: Cov qib (4.8, 5.6, 8.8) nrog lub zog tensile Tsawg dua los yog sib npaug rau 800 MPa thiab tawm lub zog tsawg dua lossis sib npaug li 640 MPa, haum rau kev siv qis dua -load applications.
A325: Siab- lub zog (ISO 8.8 sib npaug) nrog lub zog tensile Ntau dua lossis sib npaug li 830 MPa, zoo tagnrho rau cov qauv steel qauv loads.
A490: Ultra- siab- lub zog (ISO 10.9 sib npaug) nrog lub zog tensile Ntau dua lossis sib npaug rau 1040 MPa, tsim kho rau hnyav- thauj khoom sib txuas tseem ceeb.
Material & Manufacturing txheej txheem:
Txheem hex bolts: Feem ntau ua los ntawm cov pa roj carbon zoo tib yam (xws li Q235, 45 # steel) nrog cov txheej txheem tsim khoom yooj yim; Kev kho deg txwv rau cov oxide dub lossis zinc plating.
A325/A490: A325 siv carbon/low- alloy steel nrog quenching-tempering kho cua sov; A490 ntiav cov khoom nruab nrab- carbon alloy steel nrog kev tswj xyuas kom sov dua. Ob qho tib si muaj kev tiv thaiv saum npoo av (xws li, kub-dip galvanizing, Dacromet) txhawm rau txhim kho cov kav ntev.
Application Scenarios:
Standard hex bolts: Siv nyob rau hauv tsis yog - cov qauv tseem ceeb (piv txwv li, tsev neeg rooj tog, lub teeb machinery) nrog tsawg load- bearing xav tau.
A325/A490: Tshwj xeeb tsim rau cov qauv hlau, ua haujlwm ruaj ntseg hauv kev tsim kho, txuas hniav, tshuab hnyav, thiab lwm yam kev ntseeg siab siab.
Ib -Stop Usage Specifications:
Standard hex bolts: Flexible installation tsis muaj nruj torque yuav tsum tau; rov siv tau.
A325/A490: Yuav tsum muaj lub zog meej- tswj kev teeb tsa, yuav tsum tau ua ke nrog siab - lub zog ceev thiab ntxhua khaub ncaws; rov siv dua yog txwv tsis pub siv los tiv thaiv kev ua haujlwm tsis zoo.
Hauv cov ntsiab lus, A325 / A490 yog "siab-kev ua tau zoo" hex bolts haum rau steel qauv kev nyab xeeb, muab lub zog zoo dua, ua haujlwm ntev, thiab kev ntseeg siab piv rau cov qauv hex bolts.
Tsim los ntawm 2005, peb lub tuam txhab tau hloov zuj zus tshaj li ob xyoo caum ntawm kev txhim kho txuas ntxiv mus rau hauv kev lag luam hauv cheeb tsam hauv kev lag luam fastener nrog kev ua haujlwm siab kawg -kom- xaus kev tsim khoom. Nrog rau cov txiaj ntsig txhua xyoo tshaj li RMB 130 lab, peb cov khoom lag luam suav nrog ntau hom kev lag luam los ntawm nruab nrab -ntau txog qib siab- kawg thiab tau muab faib thoob ntiaj teb
