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.
Vim yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm Molybdenum (mo) thiab chromium (CR), A335 feem ntau raug xa mus rau qhov chromium molybdenum raj. Molybdenum tsub kom lub zog ntawm cov hlau thiab muaj kev txwv ywj, muaj kev cuam tshuam tiv thaiv, cuam tshuam zoo thiab tawv. Molybdenum tsub ua kom tsis kam mus muag muag, inhibits Grand kev loj hlob, thiab ua chromium steel tsawg dua rau embrittlementLement. Molybdenum yog qhov kev ua tau zoo tshaj plaws rau kev txhim kho kub siab lub zog. Nws tseem txhim kho txoj kev corrosion tsis kam ntawm cov hlau thiab inhibits pitting corrosion. Chromium (lossis Chrome) yog qhov tseem ceeb ntawm cov hlau tsis xeb. Ib qho steel nrog 12% lossis ntau dua chromium yog suav tias yog steel hlau. Chromium yog yuav luag phem rau hauv cov nqe lus ntawm kev tiv thaiv mus rau oxidation thaum kub. Chromium nce tensile, tawm los thiab hardness nyob rau hauv chav tsev.
ASTM A335 P91 Alloy Steel Yeeb Nkab thiab Kev Kub Siab Boiler Tube yog ob qhov sib txawv yog ob qho ntau yog nyob ntawm qhov loj me, uas tsuas yog nyob ntawm daim ntawv thov. Cov yeeb nkab tau ntev yuav yog kuaj hydrostatically thiab tsis yog-ua kom muaj kev puas tsuaj rau kev qhia tshwj xeeb.
