Kev paub txog ASTM A563 HVY HEX NUTS

ASTM A563-DH txiv ntseej yog dab tsi?

ASTM A563-DH yog ib qho hnyav-hex high-strength tempered txiv ntoo. Nws yog feem ntau sib xyaw nrog A325 / A490 bolts rau steel qauv. Rau kub-dip galvanized DH txiv ntseej, threads yuav tsum tau over-tapped los them nyiaj zinc txheej thickness rau kev sib dhos.

Vim li cas passivation tseem ceeb heev rau HDG A563-DH txiv ntseej?

Tiv thaiv cov xeb dawb: Zinc yog tshuaj lom neeg. Yog tsis muaj passivation, dawb xeb tshwm sim sai nyob rau hauv cov av noo / ntsev-fog thawv thauj, uas tej zaum yuav ua rau cov neeg tsis kam lees.

Tiv thaiv zinc txheej thaum lub sij hawm thauj hiav txwv & cia.

Nyias hloov dua siab tshiab zaj duab xis yuav tsis cuam tshuam xov loj los yog go/no-go gauge.

Ntxiv kev pab cuam lub neej rau sab nraum zoov / ntug hiav txwv dej ua haujlwm.

Cov tuab kub-dip zinc txheej puas tuaj yeem hloov passivation?

Tsis yog. Cov txheej zinc tuab tsis tuaj yeem zam cov xeb dawb. Passivation ua raws li kev tiv thaiv armor rau zinc txheej, nws tsis hloov HDG zinc thickness.

Dab tsi yog cov txheej txheem tseem ceeb rau HDG A563-DH cov txiv ntoo siab zog?

Cov kab ke kom raug: Kub-dip galvanizing → hydrogen nyem ci (pre-passivation) → Passivation.

Ci yuav tsum tau ua kom tiav ua ntej passivation, kub kub yuav ua rau passivation zaj duab xis puas. Hydrogen embrittlement yuav raug tshem tawm rau tempered DH txiv ntoo.

Puas yog passivation cuam tshuam cov xov haum thiab mus / tsis mus gauge?

Tsim nyog hloov dua siab tshiab passivation zaj duab xis tsuas yog 0.5-2μm, nws yuav tsis hloov xov dimension thiab yuav tsis cuam tshuam mus / tsis-go gauge. Kev kho mob ntau dhau yuav tsum zam.
