SS LD24 is a low alloyed Lean Duplex stainless steel developed with increased Cr, Mo and N content to achieve a PRE of ≥24. The microstructure consists of a phase balance of approximately 50 % ferrite and 50 % austenite that provides much higher yield strength than AISI 304 and AISI 316. Also, it exhibits good formability and corrosion resistance.
The main applications are for details with corrosion resistance better than 304L.
UNS S32001 is characterized by:
• Good resistance to stress corrosion cracking.
• Good resistance to general corrosion.
• High mechanical strength.
• High resistance to erosion corrosion and corrosion fatigue.
Heat Treatment
Solution annealing at 1020 – 1100°C followed by water quenching.
Weldability
Very good.
