hot cold rolled 1.4562 UNS N08031 Alloy 31 round hex bar rod
1. Material introduction for Alloy 31
ALLOY 1.4562 / UNS N08031 / ALLOY 31
• Alloy 31 is a nickel, chromium and molybdenum stainless steel
with nitrogen and copper additions. It combines moderate tensile
strength and high ductility with excellent corrosion resistance in
sulfuric acid, reducing and oxidizing media and has strong
resistance to corrosion and erosion corrosion in phosphoric
environment.
• Typically the alloy has PREN of ≥ 48, which ensure that the
resistance to pitting corrosion is high.
