Lub ntsiab lus ntawm Bolt Property Classes

Raws li cov qauv tsim nyog, cov khoom vaj khoom tsev rau carbon steel thiab alloy steel bolts suav nrog ntau tshaj kaum qib, xws li 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, thiab 12.9. Bolts ntawm chav kawm 8.8 thiab siab dua yog tsim los ntawm qis- carbon alloy steel lossis nruab nrab- carbon steel thiab tau txais kev kho cua sov (quenching thiab tempering); cov no feem ntau raug cais raws li siab - lub zog bolts, thaum lwm tus raug cais raws li cov bolts zoo tib yam. Cov cuab yeej siv hauv chav kawm muaj ob ntu: thawj zaug qhia lub zog tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj, thiab qhov thib ob qhia txog qhov tawm los- rau- tensile zog piv. Stainless hlau bolts tau categorized rau ntau yam khoom vaj khoom tsev raws li hom hlau, xws li A1-50, A1-70, A1-80, A2-50, A2-70, A2-80, A3-50, A3-70, A3-80, A4-50, A4-70, A55-70, C1-50, C1-70, C1-110, C4-50, C4-70, C3-80, F1-45, thiab F1-60. Hauv cov npe no, tsab ntawv thawj zaug thiab tus lej sawv cev rau pawg stainless hlau, thaum ob tus lej tom ntej sawv cev ib feem kaum ntawm tus nqi tensile zog.
