350°C is the high end of FDA pharmaceutical sterilization temperatures, normal for this application is 320°C. The glass being used doesn't reach the transition temperature under 500°C, ie. it is considered hard and brittle at the temperaturesit is being soaked in. At ambient, the glass moves freely on a polished 304SS surface, non eventful. When the metal is brough up to the steriliing temperature, it developes a dull wheat straw color/surface and the glass stalls. Is there another austenitic or super alloy which is less likely to reduce in this enviroment?
Thanks
