بیشترAbstract. Titanium-stabilized AISI 321 material (UNS S32100) is generally preferred in the pressure vessel industry as it is not sensitive to intergranular corrosion. In critical applications, the fatigue behavior of weld seams is among the most stringent requirements. The microstructural characteristics and fatigue performance double-side …
بیشترThe production of compensators (expansion joints), and especially of bellows as their most demanding elements, requires the usage of stainless materials. These stainless materials exhibit certain particularities at welding (and quality control) since they are very thin, i.e., their thickness ranges usually from 0.12 to 3.00 mm. This paper starts …
