Material Description

LDX 2101 is a low Ni-alloyed duplex with balanced chemistry of chromium, molybdenum and nitrogen content to achieve good resistance to localized and uniform corrosion. The duplex microstructure contributes to the high strength and high resistance to stress corrosion cracking. Duplex steels have good weldability. Due to risk of embrittlement, LDX 2101 should not be used at temperatures above 250°C. Very price stable high strength alloy.

APPLICATIONS

The main applications are for details with corrosion resistance better than 304L. LDX 2101 is characterized by:
• Ideal for tank production where corrosion strength is sufficient
• Good resistance to stress corrosion cracking.
• Good resistance to general corrosion.
• High mechanical strength.
• High resistance to erosion corrosion and corrosion fatigue.
