Known for their superior resistance to high temperatures and corrosive environments, these tubes are widely used in industries such as chemical processing, power generation, heat treatment, and furnace applications.

What is Stainless Steel 310S?

Stainless Steel 310S is an austenitic stainless steel alloy containing 25% chromium and 20% nickel, which makes it highly resistant to oxidation and scaling even at elevated temperatures up to 1100°C (2010°F). The “S” in 310S denotes its low carbon content, which minimizes carbide precipitation during welding and enhances resistance to sensitization.

This makes SS 310S Tubes ideal for high-temperature services where both strength and corrosion resistance are critical.

Key Features of Stainless Steel 310S Tubes

Excellent High-Temperature Strength: Performs reliably in environments up to 1100°C.

Superior Oxidation Resistance: Protects against scaling and oxidation even under cyclic heating.

Low Carbon Content: Prevents embrittlement and ensures excellent weldability.

Corrosion Resistance: Effective against sulfuric acids, nitric ...
... acids, and other chemical exposures.

Versatility: Available in seamless, welded, and ERW tube forms to meet varied industrial needs.

Types of Stainless Steel 310S Tubes

Seamless Tubes – Ideal for high-pressure and high-temperature applications.

Welded Tubes – Economical and widely used in lower pressure and structural applications.

ERW Tubes – Manufactured through electric resistance welding, suitable for mechanical and structural uses.

Polished Tubes – Used in decorative, architectural, and hygienic industries.
