Product Details

Here is a pointwise technical and marketing description for Duplex 2205 Hex Nuts that you can use for your catalog, website, or customer communication: Duplex 2205 Hex Nuts – Description Material Composition: Duplex 2205 (UNS S32205 / S31803) is a nitrogen-enhanced duplex stainless steel combining austenitic and ferritic microstructures. Chemical composition includes ~22% Chromium, ~5–6% Nickel, ~3% Molybdenum, and ~0.14–0.20% Nitrogen. Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking (SCC). Performs better than 316/316L in aggressive chemical and marine environments. High Strength: Yield strength is almost double that of conventional austenitic stainless steels (such as SS 304 and SS 316). Ideal for load-bearing and high-pressure applications. Applications: Used in desalination plants, offshore oil and gas platforms, pressure vessels, heat exchangers, and chemical process equipment. Also suitable for paper and pulp, mining, and marine environments. Standards and Sizes: Manufactured as per international standards like ASTM A479, ASTM A276, and ASTM A182. Available in metric and inch sizes, typically in Hex Nut formats like DIN 934, ASTM A194, or custom specifications. Key Benefits: Combines strength and corrosion resistance in a cost-effective alloy. Good weldability and machinability. Lower thermal expansion than austenitic grades, providing dimensional stability in service. Surface Finish Options: Available in plain finish, passivated, or coated (e.g., PTFE or Xylan) based on application. Why Choose Aanuraj Fasteners Pvt Ltd for Duplex 2205 Hex Nuts?
