Stainless Steel 347
Austenitic chromium / nickel stainless steel stabilized with columbium and tantalum, this gives it a more homogeneous behavior to corrosion at high temperatures as well as in contact with various acids
Products
Steel used in various products where greater resistance to chemical attacks is required than with 304 steel
Most Common uses and Applications
It is used in the chemical and petrochemical industry, food and in high temperature applications such as waste incineration plants
