Raws li cov hlau maraging tau ntxiv dag zog los ntawm nag lossis daus ntawm intermetallic tebchaw tsim los ntawm qee cov ntsiab lus hlau thaum lub sij hawm laus es tsis yog los ntawm supersaturated tov ntawm carbon los yog carbide nag lossis daus, cov pa roj carbon hauv cov hlau, xws li sulfur thiab phosphorus, yog ib qho teeb meem impurity. Nws yuav tsum tau hais tias qhov qis dua cov ntsiab lus carbon yog, qhov zoo dua. Feem ntau, nws yuav tsum tsis txhob ntau tshaj {{0}}.03 feem pua (rau lub hom phiaj tseem ceeb, nws yuav tsum tsawg dua 0.01 feem pua ). Cov ntsiab lus tseem ceeb hauv cov hlau yog npib tsib xee, cobalt, molybdenum, titanium,
Chromium thiab manganese tuaj yeem siv los hloov cov nickel thiab cobalt hauv maraging steels, thiab tungsten kuj tuaj yeem siv los hloov molybdenum lossis vanadium tuaj yeem siv los hloov cobalt hauv cov hlau tsis muaj cobalt tsis ntev los no. Silicon yog ib qho impurity, thiab nws cov ntsiab lus yuav tsum tsis pub tshaj {{0}}.1 feem pua . Aluminium I feem ntau yog ntxiv rau deoxidizer hauv steelmaking, thiab nws cov seem seem ntawm 0.05 feem pua rau 0.2 feem pua. Tsis tas li ntawd, cov kab mob xws li boron, zirconium, calcium, magnesium thiab tsawg lub ntiaj teb cov ntsiab lus tuaj yeem siv los txhim kho qee cov khoom ntawm cov hlau.
