2205 Duplex Stainless Steel Coil is a high-performance duplex alloy supplied by Jiangsu Cunrui Metal Products Co., Ltd. Combining the strength of ferritic stainless steel with the corrosion resistance of austenitic grades, this coil offers exceptional durability, high tensile strength, and excellent resistance to pitting and crevice corrosion.
Each 2205 Duplex Stainless Steel Coil / Sheet / Strip is manufactured in compliance with international standards such as ASTM A240, ASTM A789, and EN 10088. All coils are supplied with Mill Test Certificates (MTC), chemical composition analysis, and optional third-party inspection certificates to ensure consistent quality and reliability.
Key Features & Advantages
Superior corrosion resistance in chloride environments, chemical processing, and marine applications.
High strength reduces required wall thickness, saving material costs without compromising safety.
Stable mechanical properties with excellent wear and abrasion resistance.
Certified quality with ISO, PED, and third-party inspection compliance.
Long service life ensures cost-effective performance compared to traditional austenitic steels.
Applications
2205 Duplex Stainless Steel Coil is widely used in industries requiring both strength and corrosion resistance:
Offshore and marine engineering components
Chemical and petrochemical processing equipment
Seawater desalination systems
Heat exchangers, tanks, and pressure vessels
Pulp and paper industry equipment
Oil & gas pipelines and pressure lines
