Wear Resistance of High-Chromium Steels in an Air-Abrasive Medium at High Temperatures

摘要

The effect of chromium, aluminum and silicon on the wear of high-alloy chromium steels in abrasive media at high temperatures has been investigated. The steels were melted in high-frequency furnace and cast into specimens 50 mm in diameter and 10 mm thick. The effect of chromium content on the abrasive wear was tested on steel specimens containing 0.35% carbon, 3.1% aluminum, 0.8% silicon, 0.3% manganese and 12--30% chromium. (Author)
