Tsawg alloy cam khwb cia hlau hais txog alloy cam khwb cia hlau nrog cov ntsiab lus carbon tsawg dua 0.45% thiab tag nrho cov ntsiab lus ntawm lwm cov alloying ntsiab tsis tshaj 5%. Tsawg alloy cam khwb cia hlau muaj lub zog siab, zoo toughness thiab hardenability. Tsawg alloy cam khwb cia hlau feem ntau muaj cov ntsiab lus alloying xws li manganese, chromium, tooj liab, npib tsib xee, molybdenum, thiab vanadium. Lawv muaj kev cuam tshuam ntau dua toughness thiab tuaj yeem tau txais cov cuab yeej zoo dua los ntawm kev kho cua sov. Kev tiv thaiv corrosion thiab hnav tsis kam ntawm cov hlau tsis tshua muaj hlau cam khwb cia zoo dua li carbon steel, uas tuaj yeem txo qhov hnyav ntawm qhov chaw thiab nce kev pab cuam lub neej.
