904L is an austenitic stainless steel. Though notably softer than 316L, its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids and in particular its copper addition gives it useful corrosion resistance to all concentrations of sulphuric acid
Furthermore, multi-function signals and pulse train signals for monitoring purposes are output from the 3G3MV Inverters. C Energy-saving Control A three-phase induction motor will slow down with a decrease in supply voltage if the load is light. Using these
2.4 Microstructural AnalysisAfter high temperature confocal microscopy, embedded the sample with different cooling rates, Fig. 2 shows the embedding method, the top of the sample were mechanically polished with multiple passes of sandpaper, and then electrolytically etched for 60 s (10% oxalic acid, 6 V voltage, and 0.5 A/cm 2).
