Raws li peb cov kev sib tham yav dhau los ntawm kev txheeb xyuas cov kev daws teeb meem - kho stainless hlau bolts rau cov neeg khiav dej num kub thiab kev sib piv ntawm 304/316 cov ntaub ntawv, qhov hardness ntawm cov khoom sib txawv tom qab kev kho mob muaj cov qauv qhia meej:
304 stainless hlau tom qab kev daws teeb meem: Hardness Tsawg dua los yog sib npaug rau HB187 (kwv yees li HRB90), kev ntxhib los mos zoo nkauj, tsis muaj qhov seem ntawm kev ntxhov siab.
316 stainless hlau tom qab kev daws teeb meem: Hardness Tsawg dua los yog sib npaug rau HB187, qee qhov siab -qib 316L tuaj yeem qis li HB150, nrog kev ua haujlwm zoo rau siab - kub nkag.
Inconel siab - kub alloy tom qab kev kho mob: Hardness kwv yees li HB200 ~ 250, ntsuas lub zog thiab toughness, haum rau siab -load kub khiav daim ntawv thov saum toj no 300℃.
Bolts nyob rau hauv no hardness ntau yam tsis muaj kev ntxhov siab nyob rau hauv, tsis yooj yim rau deformation thiab breakage nyob rau hauv lub sij hawm ntev - kub kub, thiab yog haum rau kub khiav installation yuav tsum tau.
