What is the wear resistance of high-chromium cast iron at high temperatures?
Thread Content
At room temperature, high-chromium cast iron has very high wear resistance. In ball mill machines, the wear resistance of high-chromium cast iron grinding balls is 40 times that of ordinary forged steel grinding balls. How does its wear resistance change at high temperatures? By how much does its wear resistance decrease at 850°C compared to room temperature? I hope those who have studied this can come and discuss it.
High-chromium cast iron contains 20% to 35% chromium; it has good casting properties and heat resistance, allowing it to operate at 1100°C. Its wear resistance is superior to that of 188. The above is the information provided; I’m not aware of exactly by how much its wear resistance exceeds that of 188. Looking forward to an answer!
