The 0Cr27Al7Mo2 alloy contains 27% chromium, 7% aluminum, and 2% molybdenum, forming a robust protective oxide layer during high-temperature operation. The aluminum ensures long-term oxidation resistance, while chromium enhances high-temperature strength and corrosion resistance. Molybdenum improves creep resistance, allowing the bar to maintain mechanical integrity under sustained high temperatures. This makes it suitable for furnace components that operate continuously above 1,300°C, where ordinary materials would quickly degrade.
