High Chromium White Cast Iron (High Cr White Iron)
High Chromium White Cast Iron, or High Cr White Iron grades are used in wear applications that require some corrosion resistance. One common application using High Chrome White Iron alloys is in Pump and Valve parts for the Mining industry.
The high chromium content offers the corrosion resistance and the fine carbides dispersed throughout provide the hardness. These grades cannot be welded.
