HI-CHROME GRANDING MEDIA

EVALUATION OF HI-CHROME

  • Among Fe alloys chromium cast irons are specific group of materials, which characterize themselves for very high resistance on abrasive
  • HI-CHROME Irons are the first true alloyed Abrasive Resistant irons in commercial production since
  • Ferrous Matrix Flexibility of Hi-Chrome Irons, makes it available for wide range of applications
  • In 1950, MAGOTTEAUX developed first Cast Chromium Balls in its foundry at
  • MAGOTTEAUX has developed over 150 types of Hi-chrome compositions by varying alloying & Heat treatment procedures for each specific application

EVALUATION CONDT….

  • Chromium cast irons contain carbon ranging from 2 to 4% and chromium from 5 to 30%.
  • Besides chromium, Nickel and Molybdenum ranging from 3% to 5% are also added to achieve the required microstructure made up of desired matrix and carbides

CHEMICAL COMPOSITION OF HI-CHROME

  • Hi-Chrome Steel: With lower percentages of Carbon in the metal, the Hi-chrome steel are known for their impact resistance and low wearing
  • Hi Chrome Iron: With varying Carbon content in the metal, selected for suitable application, these offer high wear resistant

MICROSTRUCTURE

  • As cast Microstructure of Hi-Chrome Irons (based on the chemical composition) can easily be
  • Ferritic
  • Pearlitic
  • Bainitic
  • Martensitic
  • Austentic
  • Mixture of all
