Description

ASTM A182 F51 Duplex Steel Forged Weldneck Flange RF B16.5 For Oil And Gas

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.
