Kev Ntsuam Xyuas Cov Khoom Siv Thiab Cov Qauv Rau Qib 8.8 Bolts

Tsis muaj cov ntaub ntawv tshwj xeeb rauQib 8.8 bolts;Tsuas yog qhov kev tso cai ntawm cov tshuaj muaj pes tsawg leeg yog txhais. Txhua yam khoom ua tau raws li qhov yuav tsum tau muaj nyob rau hauv qhov no tuaj yeem siv rau kev tsim qib 8.8 siab - lub zog bolts. Txawm li cas los xij, ntau tus kws tshaj lij tseem suav cov qauv rau Qib 8.8 bolts yog qhov tseem ceeb rau kev xaiv cov khoom siv.

Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm Qib 8.8 bolts rau kev siv sib txawv, cov khoom siv yuav tsum tau txais kev kho cua sov tshwj xeeb (quenching + tempering) kom ua tiav cov yam ntxwv hauv qab no:

Lub zog tensile nominal ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 800MPa;

Qhov sib piv ntawm cov khoom lag luam (yield zog / tensile zog) ntawm cov khoom siv ntsia liaj qhov rooj yog 0.8;

Lub nominal yield zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 800MPa × 0.8=640MPa;

Rau kev xaiv cov khoom ntawm Qib 8.8 hex taub hau bolts: 1035ACR (rau M10 thiab hauv qab), 1040ACR (rau M12 thiab siab dua), CH38F, 1045ACR, 1039, 10B21, 10B33, 10B38, thiab lwm yam, muaj feem xyuam;
