1. A total of six grades: HT100, HT150, HT200, HT250, HT300, HT350
1. Chemical composition: Wc = 2.4% ~ 2.8%
2. Manufacturing method: malleable cast iron is a cast iron with a certain composition of white cast iron, which is obtained by graphitizing and annealing for a long period of time and has a graphite flocculent.
3. Graphitization annealing process: 900 ~ 1000 ℃ for 15 hours, then slowly cooled with the furnace to below 650 ℃ and then air-cooled to obtain F-matrix malleable iron
