sensitized stainless steel
in the temperature range of 450 ~ 800 ℃ stay for some time without the heat treatment does not contain titanium or niobium, stainless steelWorld Steel Pipe . The
this stainless steel in this temperature zone to stay along the grain boundary precipitation mainly to Cr23C6World Steel Pipe , carbides, resulting in near the grain boundary chromium content decreased the corrosion resistance decreased, which in the corrosive medium prone to intergranular corrosion.
450 ~ 800 ° C temperature zone is called the temperature zone of sensitized stainless steel. Titanium or niobium stabilized stainless steel, if the temperature zone of the sensitized long-term stay, there are still likely to occur intergranular corrosion.
