Effect of Heat Treatment Temperature on Microstructure and Properties of High Chromium Cast Iron (2)
/in Castings /by Sara WuThe hardness of the tested sample after heat treatment at medium temperature (740 ~ 820 °c) is shown in Table 3. The corresponding metallograph is shown in Fig. 2. It can be seen that the hardness of hypoeutectic high chromium cast iron after heat treatment at medium temperature has significant change compared with the as-cast […]
