Shanghai Iron & Steel Casting Factory and the Shanghai Institute of Machinery Manufacturing Co., Ltd. pearlite malleable cast iron agricultural trials, has been identified on February 22 this year. The meeting was presided over by a mechanical and electrical Bureau, participating units are the Bureau of Agriculture, agricultural machinery companies, Shanghai and Nanjing City Institute of Agricultural Machinery, agricultural supply stations, suburban agricultural machinery stations. The delegates agreed that the pearlite malleable cast iron has good mechanical properties and can be partially or surface hardened, so its abrasion resistance and service life are greatly enhanced.
