LDX 2101 Hot Rolled Plate – High Strength, Low‑Ni Duplex Steel

LDX 2101 is a low Ni-alloyed duplex with balanced chemistry of chromium, molybdenum. 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.
