ER2553


Alloy Type:

ER2553  is used primarily to weld duplex stainless steels which contain approximately 25% chromium.  It has a “duplex’ micro-structure consisting of an austenite-ferrite matrix.  This duplex alloy is characterized by high tensile strength, resistance to stress corrosion cracking and improved resistance to pitting.
