冷冻机、空压机中阀片材料的品种,对阀片的寿命至关重要,当前各有关工厂除选用国产的阀片钢材如:T8A、T10A、30CrMnSi 及 PH15—7 M_o 等以外,随着改革开放的形势和其他因素,也有部份工厂选用进口阀片钢材,其中使用较多的有瑞典山特维克钢厂的阀片钢材,笔者近期参加了《山特维克钢厂的技术交流会》,现将该厂的简况和阀片钢材的有关情 The types of valve disc material in refrigerators and air compressors are critical to the life of valve discs. In addition to the domestically produced valve steels such as T8A, T10A, 30CrMnSi, and PH15-7 M_o In terms of the reform and opening up and other factors, some factories have also adopted imported valve and sheet steel, among which there are more steel sheets from Swedish Sandvik Steel Works. I recently participated in the “Technical Exchange Meeting of Sandvik Steel”. , the current situation of the plant and the related situation of valve steel
