Hauv peb lub neej txhua hnub, qhov (socket) hexagon kev ruaj ntseg screwis ntau heev. Yog li cov ntsia hlau manufacturers yuav tsum paub me ntsis txog nws. Niaj hnub no, cia peb kawm cov ntaub ntawv sib txuam ntawm cov nplauv hexagon kev ruaj ntseg ntsia hlau.
1. Cov hlau
Peb paub cov pa roj carbon steel qis, nruab nrab cov pa roj carbon steel, muaj cov pa roj carbon steel loj thiab ntau cov hlau los ntawm cov ntsiab lus hauv cov pa roj carbon steel cov khoom.
A. Tsis tshua muaj carbon hlau, C% ≤0.25%. Nws feem ntau hais txog A3 steel nyob hauv Suav teb. Nws yog lub npe hu ua 1008，1015，1018，1022 txawv teb chaws. Nws yog tsuas yog siv rau cov khoom uas tsis muaj qhov yuav tsum tau ua kom tawv, xws li qib 4.8 ntsia liaj qhov rooj, theem 4 txiv ntoo thiab screws me me.
B.Medium carbon steel, 0.25% ~ 0.45%. Tam sim no, txoj kev ua lag luam tsis siv nws.
C.Alloy hlau. Ntxiv cov alloying lub ntsiab lus rau hauv cov pa roj carbon dav hlau tuaj yeem nce qhov tshwj xeeb kev ua haujlwm ntawm cov hlau.
2. Stainless hlau
Nws qib kev ua tau zoo: 45,50,60,70,80. Nws yog mas muab faib ua austenite, martensite thiab ferrite.
3.Qhov muag
Cov khoom siv feem ntau yog tooj dag thiab tooj liab zinc alloy. Ntawm kev ua lag luam, nws feem ntau siv H62, H65, H68 tooj dag raws li qhov qauv txheem. Cov khoom xaiv ntawm qib 4.8 hexagonruaj ntseg ntsia hlau: 1008K, 1010, 1015K. Cov khoom siv yeem ntawm qib 6.8 hexagon ntsia hlau: 1032, 1035, 1040, CH38F, 1039. Cov khoom xaiv tau ntawm qib 8.8 hexagon ntsia hlau: 1035ACR (hauv qab M10), 1040ACR (saum M12), CH38F, 1045ACR, 1039 10B21, 10B33, 10B38 Cov.
Saum toj no yog cov khoom siv sib txuas ntawm cov ntsawb kab ke hexagon kev ruaj ntseg ntsia hlau. Kuv vam tias nws tuaj yeem yog txiaj ntsig rau koj.
