FAQ:
Qhov nruab nrab - carbon boron steel yog dab tsi?
- Cov khoom siv feem ntau siv rau Qib 8.8 bolts yog nruab nrab -carbon boron steel lossis nruab nrab- carbon alloy steel uas tau dhau los ua quenching thiab tempering.
- Los ntawm kev ntxiv me me ntawm boron (0.0005-0.003%) rau carbon steel, nws hardenability yog ho txhim kho, uas ua rau hardness ntau dua.
Qhov txawv ntawm Qib 8.8 thiab Qib 10.9 bolts yog dab tsi?
- Qhov txawv yog nyob ntawm lawv lub zog. Qib 10.9 bolts muaj lub zog tawm los ntawm 900 MPa thiab lub zog tensile ntawm 1040 MPa- siab dua qib 8.8 bolts. Txawm li cas los xij, Qib 10.9 bolts kuj tseem kim dua.
Dab tsi yog qhov txawv ntawm DIN 931 thiab DIN 933 hex bolts?
- DIN 931 bolts yog ib nrab xov (ib nrab- xov), thaum DIN 933 bolts yog threaded tag nrho.
- Xaiv DIN 931 thaum lub ntsia liaj qhov rooj shank hla lub qhov tshem tawm; xaiv DIN 933 yog tias yuav tsum muaj kev sib koom ua ke tag nrho ntawm qhov ntev ntawm lub ntsia liaj qhov rooj.
Qib 8.8 bolts puas tuaj yeem siv rau hauv siab - qhov kub thiab txias?
- Qhov siab tshaj plaws ua haujlwm kub txwv rau Qib 8.8 bolts yog kwv yees li 300 degree.
Qib 8.8 bolts vs. Stainless Steel bolts (A2-70 / A4-70): Koj yuav tsum xaiv qhov twg?
Nyob ntawm koj qhov kev thov tshwj xeeb.
- Lub zog: Qib 8.8 bolts (lub zog tensile: 800-830 MPa) muaj zog dua A2 -70 bolts (700 MPa); yog li ntawd, xaiv Qib 8.8 rau kev sib txuas siab.
- Corrosion kuj: Stainless hlau (Qib 304 / A2 los yog 316 / A4) deb tshaj carbon steel Qib 8.8 bolts.
- Nqe: Qib 8.8 bolts feem ntau raug nqi ntawm ib - thib peb thiab ib - ib nrab tus nqi ntawm stainless hlau bolts.
Dab tsi yog qhov txawv ntawm zinc-plated bolts thiab dub- oxide bolts?
- Zinc plating yuav tsum tau siv ib txheej zinc rau ntawm lub ntsia liaj qhov rooj ntawm qhov chaw - los ntawm electroplating los yog kub -dip galvanizing - los muab kev tiv thaiv xeb.
- Kev ua tiav ntawm cov oxide dub yuav ua rau cov yeeb yaj kiab dub oxide nyias ntawm cov ntsia hlau saum npoo los ntawm cov tshuaj oxidation tshuaj; nws cov xeb- muaj peev xwm tiv thaiv tau tsawg heev.
