Yuav ua li cas txheeb xyuas lub hardness thiab hnav tsis kam ntawm hniav hniav

Siab Hardness thiab Hnav Refilling hardness yog cov yam ntxwv yooj yim uas cov hniav hniav cov khoom uas yuav tsum muaj. Txhawm rau tshem tawm cov chips los ntawm kev ua haujlwm, ib tug serrated hniav yuav tsum nyuaj dua li cov khoom siv workpiece. Lub hardness ntawm kev txiav cov hniav txhuam cov hniav siv rau kev txiav hlau feem ntau yog li saum 60hrc, thiab cov hnav tsis kam yog lub peev xwm ntawm cov khoom siv los ntawm cov khoom hnav. Nyob rau hauv dav dav, tus nyuaj cov hniav hniav hniav hniav, qhov zoo dua nws cov hnav tsis kam.

Qhov siab dua qhov nyuaj ntawm cov tawv tawv hauv lub koom haum, cov lej me, cov khoom me me, thiab cov khoom siv ntau dua, qhov zoo dua cov hnav tsis kam. Hnav Kuj Tseem cuam tshuam nrog cov tshuaj lom neeg muaj pes tsawg leeg, lub zog, microstructure thiab qhov kub ntawm kev sib txhuam ntawm cov khoom.

Qhov muaj zog txaus thiab kev ua kom cov hniav thaiv cov hniav uas tsis muaj chipping thiab ua haujlwm hauv cov neeg kho tshuab kom muaj lub zog txaus thiab muaj zog. Kev Kub Kub Kub Kuj Kub Kub Ua Haujlwm yog lub tseem ceeb ntsuas ntsuas ntsuas qhov kev txiav kev ua haujlwm ntawm cov khoom siv ntawm cov txhuam hniav.
Nws yog hais txog kev ua yeeb yam ntawm cov hniav hniav hniav hniav kom pom zoo, hnav tsis kam, lub zog thiab tawv nyob rau hauv cov kev mob kub. Yuav tsum muaj cov hniav hniav hniav hniav hniav zoo li cas los kuj yuav tsum muaj oxidized ntawm qhov kub thiab anti-diffusion muaj peev xwm, cov ntaub ntawv yuav tsum muaj cov tshuaj ruaj khov.

Cov khoom zoo thermal no thiab thermal poob siab yuav zoo dua cov khoom siv hniav, qhov yooj yim nws yog rau kev txiav tawm ntawm qhov chaw txiav, uas tau txais txiaj ntsig kom txo tau qhov ntsuas kub.
