Microstructure
Alloy B has a face-centered cubic (FCC) structure. Its chemical composition is designed to provide exceptional resistance to reducing environments, particularly moderate-concentration sulfuric acid and other non-oxidizing acids.
Features
Excellent corrosion resistance in reducing environments, such as sulfuric acid at moderate concentrations and various non-oxidizing acids.
Resistant to chloride-induced stress corrosion cracking (SCC).
Not suitable for oxidizing environments—exposure to ferric or cupric salts may cause rapid corrosion failure.
Applications
Chemical process industries, particularly in systems handling hydrochloric, sulfuric, phosphoric, and acetic acids.
Equipment used in reducing chemical environments where oxidizing agents are absent.
