Hard chrome pas nrig, tseem hu ua chrome plated pas nrig, yog precision-enciser-engineered steel pas uas tau undergone lub zog chrome plating txheej txheem. Qhov no plating ua kom lawv lub ntsej muag tawv tawv tawv, tiv taus rau corrosion thiab hnav, thiab tag nrho cov kev ruaj khov. Feem ntau tsim los ntawm cov hlau qib siab carbon lossis alloy steel, cov pas nrig no tau kho nrog ib txheej ntawm chromium hlau, muab ib lub sleeth, ci. Lub zog chrome txheej tuab sib txawv raws li daim ntawv thov yuav tsum tab sis feem ntau yog li ntau los ntawm ob peb lub microns rau ob peb lub kaum tawm tuab. Cov pas nrig no tau siv dav hauv hydraulic thiab pneumatic cov thooj voos kheej, tshuab ua cov tshuab ua kom zoo nkauj, thiab ntau yam kev muaj tshuab muaj zog, yog lub zog, thiab thiav.
