Gas Tungsten Arc Welding (GTAW) is widely used in nuclear industry owing to its better root quality and greater control of weld pool in real time. However, the process is quite slow (75-100 mm/min) compared to other slag-based processes. This is a disadvantage especially when thicker sections need to be welded. In this work, authors …
El acero inoxidable AISI 304 es el material más común en los aceros inoxidables. Debido a que el acero inoxidable 304 contiene 18% de cromo (Cr) y 8% de níquel (Ni), también se conoce como acero inoxidable 18/8. El SS304 tiene buena procesabilidad, soldabilidad, resistencia a la corrosión, resistencia al calor, resistencia a baja

The degradation of materials involving corrosion in handling nitric acid in the spent fuel nuclear reprocessing plant is a serious issue. In the present work, the corrosion resistance of American Iron and Steel Institute (AISI) type 304L stainless steel (SS) and nitric acid grade (NAG) type 310L SS in 1 to 11.5 M HNO3 and boiling 15.65 M …
AISI 304L stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 304L is the AISI designation for this material. S30403 is the UNS number. Additionally, the British Standard (BS) designation is 304S12. This material is well established: the Further Reading section below cites a number of …

Table 6 displays the AISI 304L reaction for material removal rate (MRR) within the three levels of each selected input parameter in this study. The highest values of MRR were achieved in abrasive waterjet contour cutting of AISI 304L, with 421.2 mm³/min for 4 mm, 767.10 mm³/min for 8 mm, and 811.4 mm³/min for 12 mm material thicknesses.
The AISI 304L bar material was prepared applying a silicon carbide grinding paper with a grit of 1200, followed by a subsequent cleaning process with ethanol in an ultrasonic bath for 5 min. The brazing process was carried out acc. to previous optimisations in [ 12 ] in a vacuum furnace with a vacuum of 10 −5 to 10 −6 mbar.
