Stainless Steel 347 Pipe – Industrial Performance Guide

Stainless Steel 347 Pipe is a high-performance austenitic stainless steel product designed for applications that operate under high temperatures and corrosive conditions. It is stabilized with niobium, which prevents carbide precipitation during welding and long-term heat exposure. This feature makes SS 347 Pipes highly reliable in pressure systems, refineries, power plants, and chemical industries where structural integrity is critical.

What makes Stainless Steel 347 Pipe Special

The main strength of Stainless Steel 347 Pipe lies in its resistance to intergranular corrosion and excellent heat tolerance. It maintains mechanical strength even when exposed to prolonged high temperatures, making it suitable for continuous service in extreme environments.

This grade also offers good oxidation resistance, strong weldability without post-weld heat treatment, and solid toughness across a wide temperature range. These properties ensure stable performance in demanding industrial operations.

Common Applications of SS 347 Pipes

Stainless Steel 347 Pipes are widely used in industries that require heat-resistant and corrosion-resistant piping systems.

In oil and gas refineries, they are used for high-pressure steam lines and heat exchangers. Power generation plants use them in boilers and superheaters where temperature stability is essential.

Chemical processing industries rely on SS 347 pipes for transporting aggressive fluids, while aerospace and engineering sectors use them in high-temperature structural systems.

Manufacturing Standards and Available Forms

SS 347 Pipes are manufactured according to international standards such as ASTM, ASME, and DIN to ensure durability and safety. They are available in seamless and welded constructions with various diameters, thicknesses, and finishes.

Surface options include annealed, pickled, polished, and coated finishes to suit different industrial requirements. Strict quality inspections guarantee pressure strength, dimensional accuracy, and corrosion resistance.
