Technical Review and Discussion:


Effect of Copper on the Corrosion Resistance Behaviour of As-Cast and Destabilized Cr-Mn White Cast Irons I. Chakrabarty, Banaras Hindu University, Varanasi, India


Reviewer: For commercial utilization, a comparison to higher Cr irons needs to be included.


Author: Commercial Nickel-chromium alloy (Ni-hard , grade 4) was chosen as a standard sample to compare


the performance with the experimental alloys in chlo- ride media. Unfortunately, I am unable to furnish the comparative data of commercial high chromium irons with my own experimental condition. However, I have collected some data from literature* on the ‘Icorr’ val- ues of different grades of high Cr–irons in 1000 ppm NaCl solution with pH 8.
