Jan 16, 2020Duplex stainless steels (DSS) are becoming more impressive alternative to austenitic stainless steel (ASS) because of their higher strength leading to economic benefits as well as reduction in weight . The word duplex has been coined for the coexistence of dual phase microstructure which shows alternative banded structure of austenite (lighter phase) and ferrite (darker Phase).How to Weld Type 2205 Code Plus Two Duplex Stainless Machining 2205 may be machined with high-speed steel tooling at the same speeds and feeds as Type 316L austenitic stainless steel. With carbide tooling, positive rake angle, and C-5 and C-6 grades for roughing and finishing, respectively, should be used. Cutting speeds should be reduced by about 20% from those typical for Type 316L. The highHow 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.
