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

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
