  • Heat Treating ASTM A532 | Chrome White Iron | Penticton

    The high level of chromium in high chrome white iron prevents the formation of graphite in the microstructure. Instead of graphite, the carbon in the metal becomes tied up in carbides. These relatively discontinuous chromium-rich, eutectic carbides exist with martensite to make up the microstructure. By controlling the chemistry of the metal and the heat treatment of the castings, toughness and wear resistance
