Alloy steel coil is a high-performance steel made by adding alloy elements such as chromium, nickel, and molybdenum. It has the characteristics of high strength (500-1500MPa), resistance to extreme temperatures (-60℃~600℃), wear resistance, and corrosion resistance. It is widely used in high-end manufacturing fields such as energy equipment, engineering machinery, transportation, military industry, and aerospace, and supports customized alloy composition and heat treatment process.
