ASTM A789 UNS S32205 Duplex Tube & 22 Cr Duplex Stainless Steel Pipe supplier
22 CR is a duplex alloy grade that is known to resist stress related corrosion cracking. Generally, industries that use chloride based compounds in their industries prefer the use of 22 CR Pipe because this alloy does not get degraded easily in the presence of chloride ions. There are several reasons attributed to its resistance to chloride stress related corrosion cracking.
Firstly, the dual microstructure gives it the properties of both austenite and ferrite, making this duplex alloy a highly durable one. Next is the content of chromium in the 22 Cr Duplex Pipe. If one is to compare the corrosion rate between a high chromium and a low chromium steel grade, the steel grade with a higher chromium is highly effective in resisting both general corrosion and chlorine related stress cracking. Consequently, chromium also prevents rapid oxidation of the Alloy 2205 Seamless Tube, due to the formation of a passivated oxide layer, which self heals. If the steel tube is produced keeping in accordance with ASTM A790, not only does the performance excel but the Duplex 2205 Tube would last much longer. Therefore, this specification places importance on the performance of several tests on the products. Typically, an administration of tests on the ASTM A790 UNS S31803 Duplex Pipe is to check for their conformance to the specification. Hence, tests such as hardening tests, tension tests, flattening tests, hydrostatic tests as well as nondestructive electric tests are directed to the Duplex 2205 Pipe.
