Stainless Steel 347/347H
Stainless Steel 347/347H is an austenitic chromium-nickel stainless steel stabilized with niobium (columbium) and tantalum. It offers excellent resistance to intergranular corrosion in the welded condition, making it ideal for high-temperature applications. Grade 347H is designed for enhanced strength at elevated temperatures.
