3. Outstanding Properties & Performance

3.1 Corrosion Resistance: The Ultimate Shield

• Acid Resistance: Withstands sulfuric, hydrochloric, phosphoric, and organic acids (e.g., acetic, formic) at concentrations ≤65% and temperatures up to boiling point58.

• Chloride Immunity: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater, brine, and chlorinated solvents14.

• Unique Capability: One of few alloys suitable for wet chlorine, hydrofluoric acid (HF), and flue gas desulfurization (FGD) scrubbing37.

3.2 Mechanical & Physical Properties

3.3 Fabrication Advantages

• Weldability: Compatible with TIG, MIG, plasma arc, and SMAW. No post-weld heat treatment required8.

• Formability: Excellent cold/hot workability via rolling, forging, and deep drawing68.
