By the use of metallurgical microscope and scanning electron microscope (SEM), this paper studies the effects of Cr/C on the microstructure of high chromium wear resistant and corrosion resistant cast iron with 4 percent of nickel.

High chromium molybdenum tungsten wear resistant cast irons are well known for its high hardness.

RE modification followed by heat treating will obtain more noticeable effect for the wear resistant cast iron.

Here the quenching treatment of the Cr12 wear-resistant cast iron is carried out.

In this paper, the effect of Ni, Cu and Cr/C on microstructure and properties of high chromium ferroalloy is explored by the method of contrast experiment, and the development of a new high chromium ferroalloy with wear and corrosion resistance is finished.
