Best-Selling Monel Flange - Stainless Steel F55 Bar/Plate/Pipe – Sekonic

Common Trade Names: F55, AISI 2507,UNS S32670, W.Nr 1.4501

Stainless steel F55 is a duplex (austenitic-ferritic) stainless steel containing about 40 – 50% ferrite in the annealed condition. F55 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless. The high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317L stainless in most environments. F55 is not suggested for operating temperatures up to 600°F
