Question 1

What is Stainless Steel 347 Flanges?

Accepted Answer

Stainless Steel 347 Flanges consist of various components, including chromium (17-19%), nickel (9-13%), columbium + tantalum (10xC1.0%), and molybdenum. This combination has excellent corrosion resistance and is ideal for highly acidic, high-temperature situations. Cold working strengthens the alloy, increasing its durability and strength even further. In addition to their remarkable chemical qualities, Stainless Steel 347 Flanges offer high machinability, making them simple to construct into complicated shapes and forms.

Question 2

What is the difference between SS 347 and 304 stainless steel?

Accepted Answer

347 stainless steel offers more benefits than 304 stainless steel, but the most significant is its ability to endure greater temperatures without losing strength or becoming brittle. This makes it a good choice for high-temperature applications such as turbines and boilers, where temperatures surpass 1000°F (537°C). Its increased chromium, nickel, molybdenum, titanium, and aluminum composition makes it more corrosion-resistant than 304 stainless steel. Furthermore, 347 stainless steel is nonmagnetic and has exceptional flexibility (it can be readily shaped into various forms).

Question 3

What is the grade of 347 material?

Accepted Answer

347 stainless steel is an austenitic chromium-nickel steel stabilized with columbium and tantalum. Type 347 has good intergranular corrosion and oxidation resistance at elevated temperatures. The inclusion of columbium and tantalum stabilizes this material against the production of chromium carbides.
