Alloy Steel Seamless Tube ASME/ASTM A213 T11， T12， T22， T5， T9， T91 Boiler Tube
Alloy steel tubes is a kind of steel alloyed tube with other elements in amounts of between 1 and 50% by weight to improve its mechanical properties.Alloying elements are added to achieve certain properties in the material. As a guideline，alloying elements are added in lower percentages (less than 5%) to increase strength or harden ability or in larger percentages (over 5%) to achieve special properties， such as corrosion resistance or extreme temperature stability.
Alloy steel is ideally suitable for chemical， petrochemicals and other energy-related applications. It has
characteristics of high corrosion resistance and can be used in a wide range of industrial sectors.
– Chemical industries
– Petrochemical industries
– Energy-related applications
