Tradeoffs and Variability of Mechanical Properties in Cold Worked 21-9-6 Stainless Steel Bars
- Sandia National Laboratories (SNL-NM), Albuquerque, NM (United States)
Sub-standard yield stress in a batch of 21-9-6 stainless steel (Nitronic 40) bars was observed while other batches passed requirements. This material requires enhanced property uniformity due to its application in critical components and therefore has tighter restrictions on alloying elements. Using tensile testing, this study investigates the distribution of yield and ductility across bar geometry for three lots of material and is corroborated alongside Vickers microhardness profiles.
