28Cr2Mo (GY4) qib steel phaj yog asiab -lub zog armored ballistic steeltsim los rau kev siv tub rog thiab kev nyab xeeb, ua raws li cov qauv tub rog SuavPEB 1496B-2014. Nws yog tsim tshwj xeeb los tiv taus siab - qhov kev cuam tshuam qhov nrawm nrawm thaum tuav cov txheej txheem kev ncaj ncees, ua rau nws tseem ceeb rau cov tsheb armored, moj tej tawg- tiv thaiv infrastructure, thiab cov tshuab hnyav. Hauv qab no yog cov ncauj lus kom ntxaws ntawm nws cov kev qhia tshwj xeeb, kev tsim khoom, thiab kev siv:

1. Kev qhia tshwj xeeb

Tshuaj muaj pes tsawg leeg

Element	Cov ntsiab lus (%)	Lub luag haujlwm
Cov pa roj carbon (C)	0.25–0.31	Txhim kho hardenability thiab lub zog.
Chromium (Cr)	1.80–2.30	Txhim kho corrosion kuj thiab hnav tsis kam.
Molybdenum (hli)	0.25–0.35	Suppresses temper embrittlement thiab nce creep kuj.
Silicon (Si)	0.18–0.35	Txhim kho toughness thiab oxidation kuj.
Manganese (Mn)	0.30–0.55	Txhim kho hardenability thiab hnav tsis kam.
Phosphorus (P) / Sulfur (S)	Tsawg dua lossis sib npaug li 0.030	weldability thiab ductility.
