Nyob hauv lub ntiaj teb niaj hnub no, hlau rau riam ua lub luag haujlwm tseem ceeb hauv tib neeg lub neej, raws li cov ntsiab lus no yuav tsum tau ntsib yuav luag thoob plaws hauv lub neej. Tam sim no ntau yam kev siv thev naus laus zis tau siv rau kev tsim khoom, uas txhais tau tias muaj cov alloys. Tag nrho cov impurities ntxiv yog tsim los txhim kho qhov zoo ntawm cov khoom tsim. Cov kws tshawb fawb thoob plaws ntiaj teb npau suav ntawm kev ua kom zoo ntawm cov alloys mus rau qib tom ntej, ua rau cov thev naus laus zis sib txawv thiab cov zaub mov txawv. Tam sim no, muaj qee qib steel rau riam, tso cai rau koj xaiv qhov kev xaiv zoo tshaj plaws nyob ntawm daim ntawv thov.
Muaj kev tawm tsam tas li rau lub cev zoo xws li hardness, kub tsis kam thiab hnav tsis kam. Cov riam hlau zoo yuav tsum muab kev tiv thaiv zoo rau kev nkag mus rau lwm lub cev. Ntawd yog, nws yuav tsum ua siab ntev rau qhov hnyav yam tsis muaj deforming lossis poob nws cov duab. Tsis tas li ntawd, lub peev xwm ntawm cov khoom hnav tsis muaj qhov tseem ceeb me me, uas yog vim muaj cov ntsiab lus ntawm cov carbides nyuaj (vanadium, molybdenum thiab tungsten). Nws yog vim li no uas CPM 10V thiab CPM S90V qib muajnce hnav tsis kam.
Txhua yam tshuaj nyob rau hauv nws tus kheej txoj kev cuam tshuam cov hlau rau riam, muab nws ib qho zoo lossis lwm qhov. Ib qho ntawm cov khoom tseem ceeb yog carbon, uas feem ntau txiav txim siab cov yam ntxwv tseem ceeb. Ua tsaug rau cov khoom no, nws tuaj yeem ua rau tawv hlau rau riam. Lub hardness yuav nyob ntawm seb nws qhov ratio. Txawm li cas los xij, tib lub sijhawm, cov pa roj carbon monoxide ua rau cov hlau muaj kev cuam tshuam rau corrosion. Nquag, cov ntsiab lus carbon yuav tsum tsis pub tsawg dua 0.6 feem pua, tab sis ntau lub tuam txhab tsis tau them nyiaj ntau rau qhov ntsuas no, ua cov khoom tsis zoo ntawm tus nqi qis.
Lwm yam tseem ceeb thiab tseem ceeb yog chrome. Nrog nws cov kev pab, nws muaj peev xwm ua tau zoo tiv thaiv corrosion los ntawm kev ntxiv rau cov hlau rau riam. Yog tias tus nqi ntawm cov khoom nthuav tawm tshaj 14 feem pua, ces peb tuaj yeem xav tias qhov no yog cov khoom tsis muaj stainless. Txawm li cas los xij, cov ntsiab lus siab ntawm chromium cuam tshuam rau cov yam ntxwv ntawm lub zog. Molybdenum feem ntau yog siv los ua cov khoom siv alloying, uas tuaj yeem ua rau kom sov thiab tiv thaiv corrosion. Tau kawg, nws muaj txiaj ntsig zoo rau txhua yam riam hlau.
Vanadium yog lub ntsiab lus nthuav dav, uas pab txhawb lub cev lub zog ntawm ntau yam alloys. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho hnav tsis kam thiab lub zog. Hlau rau riam enriched nrog cov khoom no muaj peev xwm tswj tau cov khoom zoo rau lub sijhawm ntev. Txawm li cas los, nws yuav tsum tau muab sau tseg tias sharpening xws li ib tug riam yuav ntau zog. Feem ntau, cov alloy muaj cob alt, uas yog tus cwj pwm los ntawm lub zog siab. Nws feem ntau muaj nyob rau hauv qib N690 thiab VG-10. Tsis tas li, riam hlau tuaj yeem suav nrog npib tsib xee, nitrogen, sulfur, silicon, titanium thiab ntau lwm yam tshuaj.
