Marquenching/Martempering: How Does it Work in Achieving Red Hardness of Steel?
Red Hardness, the terminology paints quite a picture. After a steel workpiece slides into a furnace, it soaks up so much thermal that it becomes “red hot.” Alloy microstructures alter when they reach this point. The steel hardens. More importantly, the metal retains this hardness quotient after it cools. That’s an important detail here. Marquenching, […]
