Yuav muaj kev poob qis hauv kev siv cov hlau txhaj tshuaj thiab grit, thiab yuav muaj qhov sib txawv vim yog txoj kev siv thiab cov khoom siv sib txawv. Yog li koj puas paub tias qhov kev pabcuam lub neej ntawm kev txhaj tshuaj steel nrog qhov sib txawv hardness kuj txawv?
Feem ntau, qhov hardness ntawm cov hlau txhaj tshuaj yog proportional rau nws ceev ceev, uas yog, lub hardness ntawm cov hlau txhaj tshuaj ntau dua, nws ceev ceev ceev, uas kuj txhais tau hais tias kev noj cov hlau txhaj tshuaj yuav ntau dua thiab cov kev pab cuam lub neej. yuav luv dua.
Hlau txhaj tshuaj muaj peb qhov sib txawv hardness: P (45-51HRC), H (60-68HRC), L (50-55HRC). Peb coj P hardness thiab H hardness ua piv txwv rau kev sib piv:
P hardness feem ntau yog HRC45 ~ 51, ua qee cov hlau hnyav, tuaj yeem ua kom tawv tawv rau HRC57 ~ 62. Lawv muaj cov tawv tawv zoo, kev pab lub neej ntev dua H hardness, thiab ntau yam kev siv.
H hardness yog HRC60-68, hom steel tua hardness yog siab, tub yees yog nkig heev, yooj yim heev rau tawg, lub neej luv luv, daim ntawv thov tsis dav heev. Feem ntau yog siv nyob rau hauv qhov chaw uas yuav tsum tau txhaj koob tshuaj tivthaiv peening siv.
Yog li ntawd, feem ntau ntawm cov neeg muas zaub yuav steel txhaj nrog P hardness.
Raws li kev ntsuam xyuas, peb pom tias cov voj voog ntawm cov hlau tua nrog P hardness siab dua li ntawm H hardness, H hardness yog kwv yees li 2300 npaug, thiab P hardness voj voog tuaj yeem ncav cuag 2600 zaug. Koj sim pes tsawg lub voj voog?
