D2、M2、S5模具扁钢脱碳特性实验研究

EXPERIMENTAL RESEARCH ON BEHAVIOR OF DECARBURIZATION FOR THE FLAT DIE STEELS AISI D2,M2 AND S5

开展了在空气和氮气两种气氛下 ,采用 Gleeble- 15 0 0热模拟机与普通电炉两种加热方式、不同加热温度、加热时间对 D2、M2、S5钢脱碳层深度影响的试验研究。依据试验结果 ,结合现场实际制定了较为合理的生产工艺并在现场成功应用 ,使上述模具扁钢脱碳层指标达到了美国 ASTM- A6 81技术标准。

In atmosphere and nitrogen, the effect of heating temperature and duration on the depth of decarburized layer of flat die steels AISI D2,M2 and S5 were tested on Gleeble 1500 thermo mechanical simulator and formed in electrical furnace Based on the results and real production conditions, a reasonable production technology was established for the steels, and used in the practice successfully The depth of the decarburized layer of above steels conforms with ASTM A681
