High Chromium White Cast Iron

High Chromium castings to ASTM A532

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 white cast iron (Class II of ASTM A 532) contain 11 to 23% Cr and up to 3.5% Mo and can be supplied either as-cast with an austenitic or austenitic-martensitic matrix, or heat treated with a martensitic matrix microstructure for maximum abrasion resistance and toughness.
