What temperature does it take, and what is it chosen against?

Service rating 250F to 950F (121C to 510C). That places it at the middle of the Deacon range, at a thinner consistency than 454. In practice it is chosen against 454, the denser putty in the same band, and 454-T, which is closest to this consistency.

Deacon publishes one service rating per product page and no comparison between them, so this is the part a buyer normally has to assemble by hand. Every figure above is transcribed from the manufacturer page linked on this listing.
