Qib 8.8 Hex Bolt
Muaj ntau qib sib txawv rau hex bolts, xws li 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, thiab lwm yam. Ntawm lawv, hexagonal bolts ntawm qib 8.8 thiab siab dua yog ua los ntawm cov hlau tsis tshua muaj carbon hlau lossis nruab nrab. carbon hlau. Nws nce mus txog qib sib txawv tom qab kev kho cua sov (quenching, tempering).

Muaj ntau qib sib txawv rau hex bolts, xws li 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, thiab lwm yam. Ntawm lawv, hexagonal bolts ntawm qib 8.8 thiab siab dua yog ua los ntawm cov hlau tsis tshua muaj carbon hlau lossis nruab nrab. carbon hlau. Nws nce mus txog qib sib txawv tom qab kev kho cua sov (quenching, tempering). nws feem ntau hu ua high-strength hexagonal bolts, thiab tus so yog feem ntau hu ua low carbon steel hexagonal bolts, los yog me ntsis steel hex bolts. Qib bolt muaj ob feem ntawm tus lej, uas sawv cev rau tus nqi nominal tensile lub zog thiab cov txiaj ntsig ntawm qib bolt feem. Piv txwv li:
Qib 10.9 high-strength bolts, tom qab kev kho cua sov, tuaj yeem ua tiav:
1. Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 1000MPa;
2. Qhov sib piv ntawm lub zog ntawm cov khoom siv ntsia liaj qhov rooj yog 0.9; Lub nominal yield zog ntawm cov khoom siv ntsia liaj qhov rooj yog 1000 × 0.9=900MPa
bolt qib yog tus qauv thoob ntiaj teb. Jinrui muaj kev paub dhau los hauv kev tsim cov qib sib txawv ntawm hexagonal bolts, tab sis ntawm no peb tseem xav kom txhua tus neeg hais tias txawm tias qib siab dua ntawm hexagonal bolts, qhov zoo dua, tab sis feem ntau cov teb tsuas yog xav tau qib 4.8 hex bolts. . Yuav txoj cai hex bolts ntawm tus nqi tsim nyog yog dab tsi Jinrui ib txwm tawm tswv yim.
