Cov nyhuv ntawm High Hardness Ntawm Sib Tsoo Hlau Pob

1. Lub rebound ntawm steel pob yog nruj, thiab nws yuav hloov mus rau hauv ib co zog poob thaum lub sij hawm rebound txheej txheem, yog li lub zog ntawm lub pob steel yuav tsis siv ntau rau rupture, yog li cuam tshuam rau lub rupture;

2. Thaum lub hardness ntawm lub pob steel yog siab dhau lawm, lub pob slides tiag tiag thaum nyob rau hauv kev sib cuag nrog lub pob, thiab cov ntxhia hais nruab nrab ntawm cov pob yuav tsis tau zoo meshed, uas tsis muaj zog sib tsoo nyhuv ntawm cov ntxhia hais.
