Alloy Steel Yeeb Nkab P12 Yeeb Nkab Astm A335 Hauv Tshuag
Alloy yeeb nkab yog feem pua ntawm tubular alloy cov ntsiab xws li molybdenum (mo), npib chromium (thiab lwm yam dua li cov qauv hlau txheem hlau. Qhov tseeb, ASTM A335 npog "cov roj qis" hlau steel, uas yog, muaj tsawg dua 5% tag nrho cov ntsiab lus. Qhov sib ntxiv ntawm cov khoom ntawm alloy xws li npib tsib xee thiab chromium tshuab stainless, txog li cov khoom siv stainless hlau xws li Inconel, Monel, thiab lwm yam.
Nruj me ntsis kev hais lus, txhua tus steel yog ib qho alloy, tab sis tsis yog txhua tus hlau yog hu ua "Alloy Steel". Cov hlau yooj yim tshaj plaws yog hlau (FE) suav nrog cov pa roj carbon (c) (txog 0.1% rau 1%, nyob ntawm seb puas muaj dab tsi (tshwj tsis yog cov neeg negrigible traces); Cov no yog hu ua cov hlau siv roj carbon. Txawm li cas los xij, lub sij hawm "hlau" yog tus qauv uas yog hais txog cov hlau nrog lwm cov khoom sib txuas ntxiv rau cov pa roj carbon. Ib txwm muaj willoyants suav nrog manganese (npib tsib xee), npib tsib xee, chromium, molybdenum, vanadium, silicon, thiab boron. Tsawg dua cov ubyants suav nrog txhuas, cobalt, cerium, cerium, cerium, cerium, titanium, tungsten, tin, zinc, thiab zirconium.
Cov hauv qab no yog cov ntau ntawm cov khoom txhim kho hauv Almoy cov hlau (raws li piv rau cov roj carbon hlau): lub zog, kev tiv thaiv, corrosion, thiab tawv tawv, thiab kub ntxhov. Yuav kom ua tiav qee qhov kev txhim kho cov khoom uas cov hlau yuav xav tau kho kom sov.
