Product Introduction
2205 has good weldability and can be welded using most of the welding techniques for stainless steels. Due to the balanced composition, when welded correctly, the heat affected zone contains sufficient austenite to avoid the risk of localized corrosion.
The chemical composition of Duplex 2205 is balanced to give a microstructure containing roughly equal amounts of ferrite and austenite.
Features
2205 Stainless Steel Tube Characteristic machining technology
High strength.
STANDARDS:
· ASTM/ASME: A240 UNS S32205/S31803
· EURONORM: 1.4462 X2CrNiMoN 22.5.3
· AFNOR: Z3 CrNi 22.05 AZ
· DIN: W.Nr 1.4462
CORROSION RESISTANCE:
Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments
Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions
Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)
The presence of ferrite provides for good performance of Duplex 2205 in caustic environments
HEAT RESISTANCE:
Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
Subject to embrittlement when exposed to temperatures above 572°F (300°C) even when exposed for short periods of time; Duplex 2205 is therefore not recommended for use above 572°F (300°C)
