1. Cov ntsia hlau muaj qhov ntev thiab txoj kab uas hla, muaj zog tshuab muaj peev xwm, thiab cov yeeb yaj kiab tsis zoo sib xws. Cov khoom siv tshuab tshuab tshuab no feem ntau muaj cov txiaj ntsig ntawm kev tswj qhov kub thiab txias, yog li cov tshuab cua tshuab yog qhov ci thiab sib xws, thiab muaj kev ua haujlwm zoo. Lub tshuab zoo kuj tseem siv tau yooj yim. smoothly.
2. Raws li cov chaw tsim khoom lag luam ntawm ntau hom khoom siv tshuab tshuab, lub tuam txhab tuaj yeem teeb tsa lub taub hau tig raws li qhov xav tau ntawm cov neeg siv kom ua tiav cov nyhuv tshuab ntawm cov neeg siv khoom.
3. Muaj ntau hom curling, uas tuaj yeem xaiv dawb los ntawm cov neeg siv khoom;
4. Txais kev siv tshuab thev naus laus zis ntau zaus, kev ua haujlwm siab thiab txuag hluav taws xob;
5. Lub tshuab tag nrho muaj cov qauv kev cog lus, kev ua haujlwm ruaj khov, ib sab caj npab qauv, kev lag luam thiab kev ua haujlwm, kev sib koom ua ke traction ntaus ntawv thiab kev kho tus kheej thiab nqa;
6. Cov ntsia hlau ntawm lub tshuab tshuab tshuab txais cov cuab yeej siv siab tshaj plaws, uas yog ua tiav, nrog cov tawv tawv dua, zoo dua corrosion kuj thiab lub neej ua haujlwm ntev, uas yog 2 ~ 3 npaug ntawm cov ntsia hlau nitriding.
