High red hardness
WebAs the temperature of material increases, hardness decreases and at some point a drastic change in hardness occurs. The hardness at this point is termed the hot or red hardness of that material. Such changes can be seen in materials such as heat treated alloys. Is hardness proportional to ductility? http://www.simplytoolsteel.com/high-speed-steel-comparison-chart.html
