Raw material : Steel bar

Alloy steel pipes 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.
