Plat Flange Sorf Ansi 150LB Astm C276 ASME B16.11
Alloy Steel yog hlau uas tau sib xws nrog ntau yam ntawm cov ntsiab lus hauv 1.0% thiab 50% los ntawm qhov hnyav los txhim kho nws cov khoom siv. Alloy cov hlau tawg tau tawg rau ob pawg: cov hlau qis thiab cov hlau loj. Qhov sib txawv ntawm ob yog kev sib cav. Smith thiab Hashemi txhais tau qhov sib txawv ntawm 4.0%, thaum degarmo, li al., Txhais tau nws ntawm 8.0%. [1] Feem ntau, cov kab lus \ "alloy steel " yog hais txog tsawg-alloy steels .-- Zhengzhou Huitong Pipeline Equipment Co., Ltd.
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.
