Duplex Steel Daim Hlau & Cov Ntawv Qhia & Coils
Cov khoom siv tuaj yeem yog cov cua sov kho rau anneal thiab normalize hauv huab cua, lossis quench thiab temper hauv polymer lossis roj. Alloy 4130 muaj cov ntsiab lus txo cov ntsiab lus ntawm 0.28% - 0.33% thiab me ntsis siab dua ntawm lwm cov khoom. Thiab cov khoom siv tau yooj yim rau cov txheej txheem. 4140 Tsawg Alloy Steel muaj ntau ntawm 2. 375 "txog 12.750" Od nrog cov phab ntsa thicknesses txij li 0.375 "rau 1.5". Alloy 4145 muaj cov ntsiab lus muaj roj carbon ntau dua li 4140 thiab 4130 hom cov kav dej.
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.
