2205 Duplex Stainless Steel Characteristics
Alloy 2205 (UNS S32305/S31803) is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel-nitrogen alloy. It offers high strength, excellent impact toughness, and superior overall and local stress corrosion resistance.
Compared with 316L and 317L austenitic stainless steel, 2205 alloy provides superior pitting and crevice corrosion resistance. It features high corrosion resistance, lower thermal expansion coefficient, and higher thermal conductivity than austenitic stainless steels.
The compressive strength of 2205 is twice that of austenitic stainless steel, allowing designers to reduce weight while maintaining performance, resulting in cost-effective solutions compared to 316 and 317L.

Key Features
2205 duplex stainless steel is particularly suitable for temperature ranges of -50°F to +600°F. For applications beyond this range, special considerations apply, especially for welded structures.
Common applications include: chemistry, desalination, material handling, oil and gas mining, pulp and paper, and petrochemicals. Products constructed from duplex stainless steel include cargo tanks, couplings, heat exchangers, pipes, pipe fittings, pressure vessels, and valve components.
Additional Features
Chemical and Physical Characteristics: Durable, corrosion resistant, and high-temperature resistant
Custom pipes with special specifications available according to customer requirements
