Abstract: The stationary corrosion behaviour of highpurity Fe and 316L stainless steel in liquid LiPb alloy at 350-550 ℃ was studied by rotating hang specimens method and corrosion weight loss and metallographic analysis. The results show that main reasons of materials corrosion are temperature, dissolution， and masstransfer of composition elements in liquid LiPb alloy. The oxygen scale on the surface of materials is also one of the important factors.
