Seamless Alloy Tube ASTM A213-T11 Overview
ASTM A213-T11 is a specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. These tubes are intended for high-temperature service and are commonly used in power plants, chemical plants, and refineries. The ASTM A213-T11 seamless alloy tube is made from a low alloy steel that contains chromium and molybdenum. The addition of these elements enhances the tubes strength, hardness, and resistance to corrosion. The tube is produced using the seamless process, which involves heating a solid billet and then piercing it to form a hollow tube.
Seamless Alloy Tube ASTM A213-T11 chemical composition
The "T11" in the specification refers to the grade of the alloy steel, which contains 1-1.5% chromium and 0.44-0.65% molybdenum. This combination of elements provides the alloy with excellent high-temperature strength, corrosion resistance, and oxidation resistance.
