What are Alloy Steel Tube?
Alloy Steel Tubes are hollow cylindrical components manufactured using steels alloyed with elements like chromium, molybdenum, nickel, vanadium, and manganese. These alloying elements enhance mechanical properties such as strength, toughness, and resistance to heat and corrosion.
Produced in seamless, welded, and cold-drawn forms, alloy steel tubes are used in high-temperature, high-stress environments where regular carbon steel would fail. Common grades include ASTM A213 T11/T22, ASTM A335 P5/P11/P22, and EN 10216-2 13CrMo4-5.
