The second difference is that the corrosion resistance of 316 is much better than that of 304. More importantly, molybdenum is added into 316, which improves the heat resistance. 3. The third method is different: molybdenum can further improve atmospheric corrosion, especially the corrosion resistance of the atmosphere containing chloride. Therefore, we often choose 304 stainless steel for curtain wall, side wall and roof, but 316 stainless steel is a good choice for some industries or Marine atmosphere with serious erosion. #RepairTools&Kits #Cw002 #Pins #StainlessSteel #0.15cm #20cm #Synoke #WatchesForParts #25g #DiameterStrap #MillimeterStrap #StainlessSteelStrap #SpringStrap #PinWatchStrap #RepairWatchStrap #StrappingWatchStrap #PartsWatchBand #WatchBandOfTabulator
