EDX 2304 according to MDS D35 has an improved balanced chemistry of chromium, molybdenum and nitrogen. Increased mechanical strength compared to the standard UNS 32304. EDX 2304 outruns both 1.4404 and 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.
3000 - 6000 mm
