Alloy steel castings muaj ntau qhov zoo hauv kev siv siab - kub. Lawv tuav cov khoom siv kho tshuab zoo heev hauv qhov chaw siab - qhov kub thiab txias. Muab piv rau cov hlau zoo tib yam, lawv muaj qhov txo qis hauv lub zog thiab qhov tawv, ua rau lawv tiv taus siab dua thiab thauj khoom, thiab tsis tshua muaj kev deformation thiab tawg, ua kom ruaj khov ntawm cov khoom siv nyob rau hauv siab - kub.
Lawv muaj oxidation zoo heev. Nyob rau hauv siab - cua kub, tej yam ntsiab lus nyob rau hauv cov hlau alloy, xws li chromium, tsim ib tug ntom oxide zaj duab xis uas tiv thaiv ntxiv oxygen nkag mus rau hauv, slowing down lub oxidation tus nqi thiab ncua lub neej kev pab cuam ntawm lub casting.
Lawv kuj muaj zoo thermal qaug zog tsis kam. Thaum rov ua dua thermal cycles, lawv tuaj yeem tiv taus qhov cuam tshuam ntawm thermal stress, txo cov tiam thiab nthuav tawm ntawm cov kab nrib pleb. Qhov no tso cai rau cov castings ua haujlwm tau zoo nyob rau hauv ib puag ncig nrog kev hloov pauv kub. Nyob rau hauv siab - qhov kub thiab txias corrosive ib puag ncig, alloy steel castings muaj qee qhov kev tiv thaiv corrosion, tiv thaiv kev yaig ntawm qee yam tshuaj lom neeg thiab hloov mus rau ntau txoj haujlwm ua haujlwm.
Tsis tas li ntawd, alloy steel castings muaj qhov zoo siab - kub stability. Lawv cov microstructure tseem nyob ruaj khov ntawm qhov kub thiab txias, tsis muaj kev hloov pauv tseem ceeb, ua kom muaj kev ua tau zoo thiab txhim khu kev qha.
