Saib rau cov neeg muag khoom uas muab daim ntawv pov thawj Mill Test, ua raws li cov qauv thoob ntiaj teb xws li GB / T thiab ISO, thiab muaj cov ntaub ntawv pov thawj hauv kev muab cov phiaj xwm loj. Tsis txhob cuam tshuam txog cov khoom siv zoo rau kev txuag cov nqi qis, vim tias qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo nyob deb tshaj qhov txiaj ntsig pib ntawm kev yuav khoom.

Leej twg yuav tsum siv phau ntawv qhia no? Cov ntaub ntawv no yog tsim los rau cov kws tsim qauv tsim qauv, tus thawj tswj hwm kev tsim kho, cov kws tshaj lij kev yuav khoom, thiab cov neeg tsim khoom koom nrog hauv cov haujlwm steel hnyav. Txawm hais tias koj tab tom tsim tus choj tshiab lossis cov khoom siv rau kev cog qoob loo, ua kom koj cov fasteners ua tau raws li 10.9S specification yog ib kauj ruam uas tsis sib tham mus rau kev nyab xeeb thiab kav ntev.

Cov kauj ruam tom ntej: Thaum npaj koj qhov kev sib tw tom ntej lossis kev yuav khoom, thov cov ncauj lus kom ntxaws cov ntaub ntawv thiab cov qauv ntsuas cov ntaub ntawv los ntawm cov neeg muag khoom muaj peev xwm. Tshawb xyuas lawv cov peev txheej tsim khoom thiab kev tswj xyuas zoo. Los ntawm kev siv cov kev nkag siab ntawm 2026 tus nqi sib txawv thiab cov kev qhia tshwj xeeb uas tau muab rau ntawm no, koj tuaj yeem txiav txim siab paub uas ua kom zoo dua tus nqi thiab kev ua haujlwm zoo.
