2205 Stainless Steel Plate/Sheet Details
Overview
2205 stainless steel plate/sheet is a duplex stainless steel with a balanced mix of austenitic and ferritic phases. This unique composition offers a combination of high strength, excellent corrosion resistance, and good weldability. The 2205 grade is particularly known for its resistance to stress corrosion cracking and pitting in chloride environments, making it suitable for a variety of demanding applications.
Key Characteristics
High Strength: Provides superior strength compared to common austenitic stainless steels such as 304 and 316.
Excellent Corrosion Resistance: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich environments.
Good Weldability: Can be welded using standard techniques, maintaining its mechanical properties and corrosion resistance.
Duplex Structure: The balanced austenitic-ferritic structure enhances mechanical properties and resistance to stress corrosion cracking.
Cost-Effective: Offers a cost advantage over high-nickel alloys due to its lower nickel content.
Chemical Composition
Carbon (C): ≤ 0.03%
Manganese (Mn): ≤ 2.00%
Silicon (Si): ≤ 1.00%
Phosphorus (P): ≤ 0.030%
Sulfur (S): ≤ 0.020%
