Understanding The Use Of 347 Stainless Steel Sheet In Industries

There are a range of different grades of stainless steel, each with its own features and properties that make it a good option for specific types of uses and applications. Similar to the strength of 321 stainless steel, 347 stainless steel sheet is highly resistant to corrosion, particularly intergranular corrosion, making it suitable for uses where there will be continued exposure to high heats.


The durability of 347 stainless steel sheet materials comes from the addition of columbium, cobalt or other options such as columbium and tantalum as a stabilizer. With the columbium and tantalum combination there is a ten times minimum increase in the carbon. Different stabilizers will result in slightly different carbon contents, and data on each option will be supplied from the manufacturer or the metal alloy company.

321 stainless steel, on the other hand, uses titanium. With the addition of columbium or columbium and tantalum rather than titanium this material is a good option if you do not require annealing after welding.

Depending on several factors, the range of heat that 347 stainless steel sheet material can be used in is between 800 and 1650 degrees Fahrenheit. It can stand repeated heating and cooling to a wide range of temperature. It is also non-magnetic, an important consideration in many specialized types of industries and applications.

Uses in Industry

As with most types of stainless steel, 347 stainless steel sheet materials are used in a wide range of different industries. Perhaps the most common use is in the aerospace field. This material can be found rocket engines and their parts, aircraft exhaust manifolds and in any type of gasket and expansion joints that are operated in high temperatures.

Chemical processing and chemical production equipment is also constructed out of 347 stainless steel as well as other stainless steel grades. It is considered to have a high stress rupture characteristic, making it a good option for a variety of potentially challenging applications.

Options for 347 stainless steel sheet thicknesses range from as thin as .01 to as thick as .1875 based on specific requirements of the project. Products, including tubing or bars in 347 stainless steel are also available from top suppliers, making procurement of materials for your job a simple task.
