What is material F51?
F51 - Duplex Stainless Steel
F51 tensile and yield strength is higher than conventional austenitic or ferritic grades of stainless steel. It has good weldability and good formability. Duplex steels contain both ferritic and austenitic microstructures. They have a high chromium content and a moderate nickel content.
