AISI 309S Round Stainless Steel Pipe

AISI 309S, also known as UNS S30908, is an austenitic stainless steel alloy that belongs to the 300 series. It is a modified version of the standard 309 grade, with a lower carbon content (max 0.08%), which minimizes carbide precipitation during welding, enhancing its weldability and resistance to intergranular corrosion. This alloy is primarily composed of chromium (Cr) and nickel (Ni), with the addition of silicon (Si) and manganese (Mn) to further enhance its high-temperature properties.

Product Introduction

Unique Properties

High-Temperature Resistance: AISI 309S excels in temperatures up to 1000°C (1832°F), making it ideal for furnace parts, heat exchangers, and other components exposed to extreme heat.

Excellent Corrosion Resistance: Its chromium and nickel content provides excellent resistance to oxidation and corrosion in most environments, even in the presence of sulfur-containing gases.

Good Weldability: The reduced carbon content of AISI 309S minimizes the risk of cracking during welding, ensuring easy fabrication and maintenance.

Mechanical Strength: It possesses good tensile strength and ductility, allowing it to withstand significant mechanical stresses without breaking.
