El material 1.4307 es un acero austenítico al cromo-níquel. La tendencia a solidificarse se reduce debido al bajo contenido de carbono, lo que beneficia la maquinabilidad. Se proporciona una buena resistencia a la corrosión en medios ambientales naturales. Este acero inoxidable es resistente a la corrosión intergranular y es fácil de procesar.
Plasma arc brazing is used to join the AISI 304L stainless steel and galvanized steel plate butt joints with the CuSi3Mn1 filler wire. The effect of parameters on weld surface appearance, interfacial microstructure, and composition distribution in the joint was studied. The microhardness and mechanical tests were conducted to determine the …
In order to better understand the role of uranium on the corrosion behavior of stainless in aqueous nuclear fuel reprocessing and decontamination operations, 304L stainless steel coupons were treated with nitric acid media at 45 °C and 90 °C in the presence of 0.3 M of uranyl nitrate. The impact of time, temperature, nitric acid …
FE-SEM micrographs of ASTM A36 and AISI 304L after exposure to solar salt at 390 C for 7, 14, and 21 days. Instead, depth profiles of the chemical composition obtained by GDOES were employed. The results are shown in Fig. 10, where iron and oxygen were displayed for carbon steel.
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 heat source and a cylindrical heat source is designed to perform the numerical simulation of the laser butt welding process. With the established numerical simulation …
Best suited process parameters for welding of AISI 304L and AISI 202 stainless steel of thin plates are current—65 A, welding speed—6 mm/s, CTWD—10 mm and shielding gas—pure argon. This combination of parameter gives the best results for mechanical properties that join the sheets efficiently.
Fig. 1 a shows X-ray profiles for the as-received AISI 304L and samples of AISI 304L milled for 1, 5, 10, 15, 20 and 25 h. Microstructure of the ball-milled specimens consists of a mixture of austenite [γ-phase, face-centred cubic (FCC)] and martensite [α´-phase, body-centred tetragonal (BCT)].
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.
AISI 304L / UNS S30403 / DIN 1.4307 Low Carbon Austentic Stainless Steel Alloy 304L is an extra low carbon version of type 304 chrome-nickel austenitic alloy. It is typically used for welded applications that must resist intergranular corrosion. It is strong, light
