Have done a little more studying of my companies refractory manual.
Don't get chicken wire - max service temperature for carbon steel = 260 C - bet mild steel would be less. We only let steel fans run at a max of 270C.
304 grade stainless is the next one on the list. Max service temp = 900C
HOWEVER - 300 series stainless steels held between 500 and 900C become embrittled by the formation of an iron-chromium phase that forms over time.
Takes time to form, doesn't really cause too much problem at temperature but becomes very brittle when the installation is turned off and cooled down.
The trick would be to use the 304 stainless and consider 500C the maximum service temperature.
You can buy stainless steel chicken wire apparently, but it probably would be just as easy to get the melt extract fibres that are made for the job.
