PrecisionCold Rolled 2205 Stainless Steel Strip ASTM A240 Certified

Products Specification

Product Name: 2205 Duplex Stainless Steel Strip
Grade Standards: UNS S32205 / EN 1.4462 / DIN X2CrNiMoN22-5-3

Introduction

2205 duplex stainless steel strip is a premium-grade material engineered for industries requiring exceptional durability and resistance to harsh environments. Its balanced austenitic-ferritic microstructure delivers a unique combination of high strength, superior corrosion resistance, and cost efficiency, outperforming traditional stainless steels like 316L and 304.

Key Advantages

• Enhanced PREN Value: PREN (Pitting Resistance Equivalent) ≥35, ensuring outstanding resistance to localized corrosion.

• Thermal Stability: Maintains mechanical properties at elevated temperatures (up to 300°C/572°F).

• Sustainability: Fully recyclable and compliant with eco-friendly manufacturing standards.

• Versatility: Adaptable to precision forming, stamping, and machining processes.

Chemical Composition (%)

• Chromium (Cr): 21.0–23.0

• Nickel (Ni): 4.5–6.5

• Molybdenum (Mo): 2.5–3.5

• Nitrogen (N): 0.14–0.20

• Manganese (Mn): ≤2.0

• Silicon (Si): ≤1.0

• Carbon (C): ≤0.03

• Iron (Fe): Balance
