| Abstract |
Sticking phenomenon occurring during hot rolling of ferritic stainless steels, STS 430J1L
and STS 436L, was investigated in this study. The simulation test results at 900 oC and 1000 oC
revealed that STS 430J1L had a smaller number of sticking nucleation sites than the STS 436L.
When the test temperature was 1070 oC, the sticking hardly occurred in both stainless steels as Fe-
Cr oxide layers were formed on the surface of the rolled materials. These findings suggested that
the improvement of high-temperature properties of stainless steels and the appropriate rolling
conditions for readily forming oxide layers on the rolled material surface were required in order to
prevent or minimize the sticking. |
