1. Supernormal hnav tsis kam: Cov hnav tsis kam ntawm lub phaj hnav-tiv taus yog 10-30 lub sij hawm siab dua li cov hlau zoo tib yam, 5 npaug siab dua li cov hlau tsis muaj hlau thiab cov hlau manganese siab, thiab 1 zaug siab dua uas yog cam khwb cia siab chromium hlau, uas yog roughly sib npaug rau ceramics. HRC hardness tsis tsawg dua 63
2. Muaj kev cuam tshuam tsis zoo: Qhov saum npoo ntawm lub phaj hnav-resistant yog ua los ntawm cov ntaub ntawv superhard uas muaj ntau yam xws li chromium carbide. Nws muaj ob qhov zoo ntawm ob qho tib si hnav tsis kam thiab cuam tshuam toughness. Txawm li cas los xij, cov tsoos castings muaj kev cuam tshuam tsis zoo thiab yog cov nkig thiab ua rau tawg.
3. Kev ua tau zoo ntawm kev ua haujlwm: Cov neeg ua haujlwm tu tuaj yeem txiav thiab ua cov ntawv hnav-resistant steel raws li qhov ntev ntawm qhov chaw, thiab yooj yim welded rau ntawm qhov chaw hnav. Lawv kuj tuaj yeem ua tiav rau hauv qhov countersunk qhov thiab txuas nrog cov khoom siv nrog bolts. Nws tseem tuaj yeem khoov thiab ua tiav rau hauv cov kav dej hnav-tiv taus, plua plav tshem tawm lub luj tshib, thiab ntau yam tsis sib xws. Txawm li cas los xij, cov hlau cam khwb cia hnav-tiv taus tsis tuaj yeem sib sau los ntawm vuam, thiab nws tseem nyuaj rau cam khwb cia loj-qhov hnav-tiv taus daim hlau los ntawm cam khwb cia hlau.
4. Kev ua haujlwm siab thiab tus nqi qis: Txawm hais tias tus nqi ntawm kev siv overlay welded hnav-resistant daim hlau yog nce los ntawm 3-5 lub sij hawm ntawm cov hlau zoo tib yam, nws yog 25% pheej yig dua li siab chromium stainless hlau castings. Txawm li cas los xij, xav txog kev pabcuam lub neej ntawm cov khoom siv, txo cov nqi kho, txo sijhawm thiab kev tsim khoom qeeb, thiab tag nrho lwm cov tib neeg thiab nyiaj txiag poob. Vim yog kev siv cov khoom siv tsim nyog, kev siv cov khoom siv sib tshooj welding hnav-resistant daim hlau tuaj yeem nqa tau ntau yam txiaj ntsig.
