Alloy Steel Yeeb Nkab P11 Yeeb Nkab Astm A335 Hauv Tshuag
Alloy Steel yog cov hlau sib cais los ntawm kev ntxiv ntau hom ntawm cov ntsiab lus nrog tag nrho cov nyiaj ntawm 1.0% thiab 50% txhawm rau txhim kho nws cov khoom siv. Alloy Steel tau muab faib ua ob pawg: cov hlau tsis tshua muaj hlau thiab cov hlau loj. Qhov sib txawv ntawm ob yog kev debatable. Smith thiab Hashemi txhais qhov txawv li 4.0%, thaum degarmo li al. txhais qhov txawv li 8.0%. Feem ntau, cov kab lus "alloy steel" yog hais txog cov hlau tsis tshua muaj hlau.
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.
ASTM A335 P91 Cov Yeeb Nkab yog qhov yeeb nkab zoo rau kev kub siab. P91 Tubing yog qhov zoo rau khoov, flanging lossis rau vuam thiab ua haujlwm zoo sib xws. Cov khoom siv ntawm cov hlau yuav tsum ua raws li cov cai ntawm cov tshuaj muaj tshuaj, lub zog tensile thiab hardness.
