Hi all,

I'm writing to actally seek help on this term glass media

 

the whole sentence:- Possible of  mismatch of thermal co-efficients of expansion between 300 sst and glass media.

 

Can anyone help pls,

Stevie

Stevie,
I think they are just speaking about basic glass material.. glass.
There is most certainly a large difference in the thermal expansion rates between stainless steels and glass materials. This is what I believe they are referencing.

I think this is because most glasses will have a very similar thermal co-effecient. Just as most stainless steels will have a similar thermal co-effecient.

Example, if you placed a steel ring inside of a round hole in glass and let the sun heat them both, the steel would expand in diameter at a faster rate. If the steel ring fits the glass hole tight in a cool morning and later the sun warmed them on a hot day the steel would expand and shatter the glass. The same problem would occur if you tried to bond a glass plate to a steel sheet without some way to allow for the thermal expansion differences.

It is common for artist and scientists to refer to any basic material group as a media, ... clay, paint, wood, brick, concrete, glass, air, fluids, .... and so on.
