salt bath austempering

[onim]

what is the maximum critical quench delay time in austempering 1050 carbon steel from a high temperature salt bath to quenching bath hardness range Hrc 42-48

What is your application? This question sounds awfully like a typical materials process class homework question. If so, go find TTT and CCT diagrams for AISI Type 1050 carbon steel. By the way, only a hot salt bath is used to quench from the austenitizing temperature - a second quench is not required for austempering.

metengr,

I think onim was indicating that the heat source for austenitizing is a high temperature salt bath, not an atmosphere-type furnace.

onim,
