MATERIAL DESCRIPTION FOR EDX 2304 / 1.4362 / LEAN DUPLEX UNS S32304 

Lean Duplex Stainless Steel according to NORSOK M-120 MDS YD35 has an improved balanced chemistry of chromium, molybdenum and nitrogen content, resulting in a PRE value ≥ 28 and increased mechanical strength compared to the standard EN 1.4362 / UNS 32304. This grade outruns AISI 316L acc. to both EN 1.4404 & EN 1.4436 with respect to pitting corrosion resistance. Due to risk of embrittlement, duplex steels should not be used at temperatures above 250 – 325°C.
