ASTM A213 T24 Alloy Steel Tube For Water Wall Panels in Boilers
Specification
ASTM A213 T24 alloy steel tube is designed for high-temperature applications like boilers, superheaters, and heat exchangers. It is a chrome-moly tube, meaning it contains chromium and molybdenum, with a specific composition of about 2.20-2.60% chromium and 0.90-1.10% molybdenum. Key characteristics include good high-temperature strength, oxidation resistance, and durability.
