Puas yog Qib 8.8 Bolts Kub Kub Resistant?
Qib 8.8 bolts yog ib hom kev siv lub zog siab, tshwj xeeb tshaj yog nrov hauv kev tsim kho, tsheb, thiab kev siv engineering dav dav vim lawv qhov kev ntseeg tau muaj zog thiab kav ntev.
Yam ntxwv
1. Cov khoom xyaw: Feem ntau, Qib 8.8 bolts yog tsim los ntawm cov hlau tsis tshua muaj hlau lossis cov pa roj carbon nruab nrab uas tau raug kho cua sov (quenched thiab tempered) kom ua tiav cov khoom siv kho tshuab uas xav tau.
2. Mechanical Properties:
- Tensile Strength: Qib 8.8 bolts muaj lub zog tensile yam tsawg kawg nkaus ntawm 800 N / mm² (800 MPa).
- Yield Strength: Lub zog tawm los, uas yog lub ntsiab lus uas lub ntsia liaj qhov rooj yuav pib deform plastically, yog tsawg kawg yog 640 N / mm² (640 MPa), uas yog 80% ntawm lub zog tensile.
- Elongation: Qhov feem pua elongation feem ntau yog nyob ib ncig ntawm 15%, qhia tias cov khoom muaj peev xwm ncav cuag ua ntej tawg.
3. Xov Tsim: Cov bolts no ua raws li cov qauv tsim qauv, ua kom muaj kev sib raug zoo nrog lwm cov fasteners thiab cov khoom hauv tib lub zog.
4. Nto tiav: Nyob ntawm daim ntawv thov, Qib 8.8 bolts tuaj yeem tuaj nrog ntau qhov chaw ua tiav, suav nrog cov txheej txheem galvanized, zinc plating, lossis lwm yam kev kho los tiv thaiv corrosion los txhim kho lawv cov kav ntev hauv qhov chaw hnyav.
Puas yog Qib 8.8 Bolts Kub Kub Resistant?
Qib 8.8 bolts muaj cov khoom siv zoo ntawm qhov kub thiab txias (feem ntau qis dua 100 ° C), tab sis lawv qhov kev ua tau zoo yuav raug cuam tshuam thaum qhov kub siab tshaj qhov txwv. Feem ntau, Qib 8.8 bolts tseem tuaj yeem tswj tau lawv lub zog feem ntau ntawm thaj tsam 150 ° C, tab sis lawv lub zog yuav raug txo qis thaum qhov kub nce ntxiv. Tsis tas li ntawd, kev siv mus sij hawm ntev hauv qhov chaw kub kub yuav ua rau Creep, Oxidation lossis lwm yam degradation tshwm sim ntawm cov khoom, uas cuam tshuam rau kev ntseeg siab thiab kev pabcuam lub neej ntawm cov bolts. Yog hais tias bolts yuav tsum tau siv nyob rau hauv ib puag ncig kub, bolts nrog cov qib siab zog (xws li 10.9 los yog 12.9) feem ntau yog xaiv, los yog tshwj xeeb tsim los ntawm high kub resistant cov ntaub ntawv xws li kub-resistant steel, stainless hlau los yog npib tsib xee alloys yog siv los tsim bolts los xyuas kom meej tias lawv tseem muaj peev xwm tswj tau txaus lub zog thiab ruaj khov ntawm qhov kub thiab txias.
Hauv luv luv, 8.8 qib bolts muaj peev xwm tiv taus qhov kub thiab txias, tab sis thaum tshaj lawv qhov ntsuas kub, nws raug nquahu kom xaiv cov khoom tsim nyog dua thiab qib bolt.
XOV XWM tsom rau kev tsim khoom ntawm precision hardware xws li Screws, Bolts, Ceev, Washers, Rivets, Xov rods, Nails, Anchors thiab cuab yeej, thiab lwm yam. Yog tias koj txaus siab rau peb cov fasteners, thov koj xav tiv tauj peb kom paub ntau ntxiv.
