Abstract In order to solve the problem of mischcrystal in 304L stainless steel with thickness over 40mm, a series critical process parameter were studied laboratory and trial product, such as rolling cycle, temperature recrystallization controlled rolling, holding time cooling mode after rolling. The results show that deformation at 1050°C 950°C has no significant effect on ratio. plate was dep...

The variability in the surface integrity, mechanical properties and corrosion resistance of layer 304 stainless steel after scale removal by pickling an abrasive water jet, removing oxide Cr-poor was studied comparatively. It found that surfaces specimens were etched with pits varying sizes, Ra 4.384 µm Rz 24.81 µm, while microhardness fluctuated a range 200–220 HV. jet exhibited stack laminar ...

Spices can be used as an alternative washing agent in fish collagen production, replacing organic materials' commonly agent. Many Asians, including Indonesian traditional culinary use spices to remove the fishy odor. Therefore this research was conducted obtain a suitable spice production. Ginger, galangal, lemongrass, bay leaves, lime and pandan leaves were tested form of 5% liquid extract wat...
