夹杂物对16MnR（HIC）钢板抗氢开裂影响

摘要

HIC test and inclusion analyses ate carried out to 16MnR heavy and medium plate with different S con-tents.The tesult show that HIC resistace is excellent when the S contemt is not greaterghan 0.005 while the dectease of idusion A is obvious and inclusion is lower ghen class0.5.
