The fiber laser butt welding of AISI 304L and Q235 low-carbon steel is performed in this study. An integrated heat source combined with an asymmetric double-ellipsoidal a cylindrical designed to perform the numerical simulation process. With established model, formation welded joint studied by investigating thermal effects power beam offset sides center gap on shape strength are experimentally ...

The oxidation of stainless steels 304 and 304L during hot rolling is studied in this paper. Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity...

An original simplified finite element model is proposed to simulate the effects of non-penetrating ballistic impacts causing so-called bullet splash phenomenon (complete fragmentation), while no fragmentation caused target. The based on Arbitrary Lagrangian Eulerian formulation (ALE) and it simulates impact as a fluid-structure interaction. has been tested by experimental analyses AISI 304L pla...

The present research investigates the influence of surface roughness imparted by cold finishing processes on localized corrosion resistance stainless steel. Five different alloys were studied: ferritic AISI 430, martensitic 430F, austenitic 303, 304L, and 316L. It was demonstrated that grinding process, executed previously drawn bars, leads to an improvement in according results obtained with e...

Abrasive waterjet machining is applied in various industries for contour cutting of heat-sensitive and difficult-to-cut materials like austenitic stainless steel 304L, with the goal ensuring high surface integrity efficiency. In alignment this manufacturing aspiration, experimental analysis optimization were carried out on abrasive 304L objectives minimizing roughness maximizing material remova...
