Chromium (Cr) yog ib qho tseem ceeb hauv 38CrMoAl, feem ntau tam sim no nyob rau hauv ib qho kev faib ua feem. Chromium txhawb kev txhim kho hardness thiab hnav tsis kam. Nws pab tsim cov txheej txheem oxide ruaj khov ntawm cov khoom siv, uas muab kev tiv thaiv corrosion zoo. Qhov no ua rau cov alloy haum rau cov ntawv thov uas raug rau ntau qhov chaw yuav tsum tau, thiab cov khoom yuav tsum tau muaj peev xwm tiv taus corrosion.

Molybdenum (Mo) yog lwm qhov tseem ceeb hauv kev sib xyaw. Nws ntxiv rau lub zog ntawm cov alloy, tshwj xeeb tshaj yog nyob rau hauv siab kub. Molybdenum kuj tseem txhim kho lub hardenability thiab toughness ntawm 38CrMoAl, tso cai rau nws kom zoo dua tiv thaiv txhua yam kev ntxhov siab thiab cuam tshuam. Qhov no yog qhov muaj txiaj ntsig zoo hauv cov ntawv thov uas cov khoom siv yuav raug rau cov khoom hnyav lossis lub zog muaj zog.
Aluminium (Al) kuj yog ib feem tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg. Aluminium plays lub luag haujlwm tseem ceeb hauv cov txheej txheem nitriding. Nws txhawb txoj kev tsim ntawm ib qho nyuaj thiab hnav-resistant nitrided txheej ntawm cov hlau alloy. Cov txheej txheej nitrided no ua rau kom cov tawv tawv thiab hnav tsis kam ntawm cov khoom siv, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum muaj cov khoom zoo, xws li hauv kev tsim cov iav, shafts, thiab lwm yam khoom siv uas yuav tsum tau ua haujlwm nrog kev sib txhuam qis thiab siab ntev.
Ntxiv rau cov ntsiab lus tseem ceeb no, 38CrMoAl tseem muaj cov khoom me me xws li carbon (C), silicon (Si), thiab manganese (Mn). Cov ntsiab lus carbon muab qhov tsim nyog lub zog thiab hardness rau lub hauv paus hlau. Silicon pab txhim kho oxidation tsis kam thiab fluidity ntawm molten hlau thaum casting. Manganese pab txhawb rau tag nrho lub zog thiab toughness ntawm alloy thiab kuj pab nyob rau hauv cov txheej txheem deoxidation thaum lub sij hawm tsim khoom.

Qhov sib npaug thiab qhov sib npaug ntawm cov ntsiab lus hauv cov tshuaj muaj pes tsawg leeg ntawm 38CrMoAl yog ua tib zoo tswj thaum lub sijhawm tsim khoom. Qhov no yog los xyuas kom meej tias cov alloy muaj cov khoom zoo ib yam thiab txhim khu kev qha, ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam kev siv hauv kev lag luam. Seb nws yog siv nyob rau hauv lub tsheb, aerospace, los yog machinery manufacturing industries, lub zoo-tsim tshuaj muaj pes tsawg leeg ntawm 38CrMoAl ua rau nws ib tug tseem ceeb thiab ntau yam khoom. Nkag siab txog nws cov tshuaj muaj pes tsawg leeg yog qhov tseem ceeb rau kev txhim kho nws cov txheej txheem tsim khoom thiab ua kom nws qhov kev ua tau zoo tshaj plaws hauv kev siv sib txawv.
