It was observed that in the buttered specimen, the structure of the weld metal was completely austenitic while the microstructure of unbuttered sample was duplex ferritic-austenitic. M23C6-type ...

The microstructure of FGHAZ and CGHAZ consisted of prior austenitic grain boundaries (PAGBs) and lath martensite, with ferrite and martensite observed in the weld metal.

We successfully weld A36 or similar grades of carbon steel to 304L or 316L stainless steel using an ER309LSi filler metal and pulsed gas metal arc welding (GMAW). Recently, we invested in automation ...

The effect of multipass welding using 309L austenitic stainless steel (ASS) filler metal was studied. The material follows ferrite to austenite (FA) mode of solidification under equilibrium cooling ...

Study of Microstructure and Hardness of Austenitic Stainless Steel 309L Multipass Weld Beads Abstract: The effect of multipass welding using 309L austenitic stainless steel (ASS) filler metal was ...

Due to their high strength (around twice that of typical austenitic or ferritic stainless steels), improved corrosion resistance and weldability, DSS alloys are ideal for valves in urea applications ...
