The Properties and Advantages of Stainless Steel 347 Tubes: A Comprehensive Guide

The Properties and Advantages of Stainless Steel 347 Tubes: A Comprehensive Guide

In a world where industries and products demand high quality and durability, stainless steel has become indispensable. Stainless steel has advanced engineering and manufacturing properties that can withstand extreme temperatures, corrosive materials, and harsh work environments. One type of stainless steel that has recently gained popularity in many fields is the 347 stainless steel tube. This type of steel is highly versatile, strong, and corrosion-resistant, giving it a wide range of appealing features for many businesses. This post will explore the properties and advantages of stainless steel 347 tubes in a comprehensive guide.

What is Stainless Steel 347 Tubes?

Stainless Steel 347 Tubes are specialized stainless steel stock used in extreme environments. They feature a higher chromium content and a unique stabilization technology that prevents corrosion even at elevated temperatures, making them an ideal choice for high-temperature chemical processing, power generation, petroleum refining, aerospace engineering and shipbuilding applications. In addition to superior corrosion resistance, these advanced tubes offer improved strength and excellent formability due to their niobium/tantalum stabilized austenitic stainless steel composition. Moreover, SS347 tubes exhibit good weldability and better machinability than other alloys of similar grade. With its strength and malleability, these tubes can be formed into any shape desired without needing heat treatment or hot working processes.

Discover the Properties and Advantages of Stainless Steel 347 Tubes

High-Temperature Resistance:

Stainless steel 347 tubes have excellent high-temperature resistance properties due to the alloy’s addition of columbium and tantalum. These two elements are designed to stabilize the steel’s structure, thus rendering the steel able to withstand extreme temperature changes without deformation, corrosion, or cracking. For this reason, 347 stainless steel tubes have become a popular choice for kitchen appliances, aircraft engines, and petrochemical processing units.

Resistance to Corrosion:

Thanks to the high presence of chromium in its composition, 347 stainless steel tubes are highly corrosion-resistant. This feature makes it a choice for applications involving corrosive chemicals or saltwater exposure. For instance, it’s used in the petroleum, chemical, and pharmaceutical industries, susceptible to corrosive compounds.

Formability and Weldability:

The stainless steel 347 tube is strong but also highly formable and weldable. It can be easily formed into various shapes, sizes, and designs and welded without compromising its integrity. This feature means it can be used in various items, including exhaust systems, tanks, piping, etc.

High-Temperature Oxidation Resistance:

At high temperatures, 347 stainless steel develops a protective oxide layer, which makes it more resistant to oxidation and rust. This is essential in high-temperature environments, such as furnaces, gas turbines, and chemical process plants. The layer provides an extra barrier against harmful corrosion agents such as acids and harsh chemicals.


As a type of stainless steel, the 347 steel tube is relatively cost-effective compared to other metals such as titanium and nickel. Despite being less expensive, it still offers outstanding durability, making it an excellent choice for businesses that value cost-effectiveness without compromising quality.


In conclusion, the stainless steel 347 tube is an excellent choice for industries that value high quality and durability. Its heat resistance, corrosion resistance, formability, weldability, oxidation resistance, and cost-effectiveness make it a superior choice for various applications. We hope this comprehensive guide helps you understand the advantages and properties of this type of steel and its suitability for your industry and application.
