Vuam txheej txheem ntawm precision steel yeeb nkab: Sib txawv ntawm cov khoom siv kav dej zoo tib yam, cov txheej txheem vuam ntawm precision steel yeeb nkab yog patented. Thaum rhuav cov txheej txheem vuam tsoos, nws tau ua tiav kev txhim kho thiab kev vam meej. Los ntawm kev xav ntawm vuam tshuab, vuam tshuab ntawm precision steel kav yog siab heev.
Vim hais tias feem ntau precision steel kav tsis muaj cov ntsiab lus carbon siab, lawv kuj muaj ntau lwm yam hlau. Nws yog qhov tseeb vim tias qhov tseeb ntawm cov kav hlau steel yog nws tus kheej muaj nyob rau hauv cov txheej txheem vuam, uas yuav tsis tsuas yog muab kev tiv thaiv tsim nyog rau sab hauv ntawm cov kav dej, tab sis kuj tseem txhim kho cov cuab yeej ntawm cov txheej txheem vuam, yog li argon arc vuam siv. .
