Alloy Tube

Sunnysteel is a merchant exporter and supplier of alloy steel pipes and alloy steel tubes used for many different purposes. We are specialized in offering precision engineered alloy steels, which are used in various engineering applications and can be availed in various grades like.
Alloy steel pipes are 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.
