A: Lawv yuav tsis xeb nyob rau hauv ib txwm siv tej yam kev mob . 304 stainless hlau muaj 18% chromium, thiab nws nto ua ib tug ntom oxide zaj duab xis, uas muaj nws tus kheej - kho muaj peev xwm. Txawm li cas los xij, nyob rau hauv ib puag ncig uas muaj zog acids, muaj zog alkalis, thiab cov ntsiab lus siab ntawm chloride ions, pitting corrosion yuav tshwm sim. Hauv cov xwm txheej zoo li no, 316 stainless hlau raug pom zoo.
Q: Cov pa roj carbon steel qib A2-70 muaj zog npaum li cas?
A: Lub zog tensile ntawm A2-70 yog ntau dua lossis sib npaug rau 700 MPa, uas yog kwv yees li qib 8.8 ntawm carbon steel (800 MPa), thiab nws yog 75% muaj zog dua li qib 4.8 (400 MPa).
Q: Dab tsi yog qhov txawv ntawm cov bolts thiab bolts zoo tib yam?
A: Carriage bolts feature tshwj xeeb tsim ntawm lub taub hau puag ncig thiab lub caj dab square. Lub taub hau puag ncig yog du thiab zoo nkauj txaus nyiam, muab kev tiv thaiv- tub sab ua haujlwm; lub caj dab square cia li tiv thaiv kev sib hloov ib zaug nws tau muab tso rau hauv lub qhov square ntawm lub workpiece, thiab tsuas yog yuav tsum tau ua haujlwm nkaus xwb - ib sab. Lub installation efficiency yog tshaj 30% siab tshaj qhov zoo tib yam bolts.
Q: Puas yog ua ntej -drilling yuav tsum tau thaum lub sij hawm installation?
A: Rau cov hlau ua haujlwm, lub qhov square sib npaug ntawm lub caj dab square yuav tsum tau ua ntej-drilled; rau ntoo, lub caj dab square tuaj yeem nias thiab kos thaum lub sijhawm teeb tsa thiab tsis muaj qhov ua ntej -drilled square qhov yog qhov tsim nyog.
