2507 Stainless steel heat exchanger tubes

2507 stainless steel heat exchange tube is a ferrite-austenite (duplex) stainless steel, the main components of which include 25% chromium, 7% nickel, 4% molybdenum and 0.27% nitrogen. Due to its high chromium and molybdenum content, 2507 stainless steel has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion.
GNEE's 2507 stainless steel boiler tube is resistant to high temperature steam, impact corrosion and ammonia corrosion; it is resistant to scaling, not easy to stain, and resistant to oxidation corrosion; it has a long service life and reduces maintenance time.
