Abstract
Already, we are developing the process to produce stainless steel foam over 97% porosity using hydro-gel binder. However, this process is very sensitive process, and foaming condition is affected by the slight deference of heating temperature. Therefore, we tried to improve the process by changing the foaming agent and foaming conditions. By the improvement of the process, the foaming operation becomes stable and finer cell size stainless steel foam can be obtained.
