Alloy steel tubes are generally available in stock with OD sizes in all standard sizes and thicknesses.On demand, we can offer our customers with high quality alloy steel pipes and tubes with black painting, anti-corrosion oil and galvanised finish.

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.
