Alloy Steel Seamless Tubes ASTM A213 T1, T11, T12
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.
