How to weld Duplex Stainless Steel - Rolled Alloys, Inc.
Because welding duplex stainless steel is not fool-proof it is important to perform quality checks. We normally suggest that when developing a weld procedure it is critical to test the corrosion resistance, the impact toughness, and the ferrite/austenite mix in the weld qualification.Ferrite Content in Austenitic Stainless Steels - Rolled martensitic thrubolt land based gas turbine WeldingThis is a precaution against solidification cracking during welding. The ferrite contents in the weld deposits will be on the order of 5 -10% ferrite depending on the alloy. If ferrite free welds are also required, higher nickel alloy filler should be selected, such Some results are removed in response to a notice of local law requirement. For more information, please see here.Fatigue Properties of As-Welded and Postweld Heat Westinghouse manufactures land-based steam turbines to generate electrical power.
