我厂生产的外科手术器械品种多、批量大,手术器械使用3Cr13马氏体不锈钢,在300T摩擦压力机上热锻成型。热锻模材料采用3Cr2W8钢,由于该材料高温强度低,高温下耐磨性差,处理后的硬度不高,模具的使用寿命一直较短,一般均在3000次左右,因此模具消耗量非常大。为了解决这个问题,我厂在上钢五厂、上海医疗器械研究所的支持和配合下,试用具有较高强度、热强度
I plant a variety of surgical instruments, large quantities, the use of surgical instruments 3Cr13 martensitic stainless steel, 300T friction press hot forging. Forging die material 3Cr2W8 steel, due to the low temperature strength of the material, high temperature wear resistance is poor, the hardness is not high after treatment, the life of the mold has been shorter, generally about 3,000 times, so the mold consumption is very large. In order to solve this problem, I plant in the steel Wuchang, Shanghai Institute of Medical Devices with the support and cooperation, try with high strength, hot strength
