Round Cold Rolled SCH5S A789 Seamless Stainless Steel Pipe
316 316L Stainless Steel Seamless Tube, Stainless Steel Welded Pipe
Products Details
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.

Corrosion Resitance
1. Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments
2. Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions
3.Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)
4. The presence of ferrite provides for good performance of Duplex 2205 in caustic environments
Heat Resitance
1.Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
2. 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)
