Heat Drop - 12L14

We perform a quick anneal (induction heater) on 0.515" 12L14material which allows us to perform some severe bends on the product.Trying to determine time for temp drop from 1100 F to below critical temp where we can force cool. Any suggestions ?

1100F is below the critical phase transformation temperatures for this steel. If you are heating the material only to 1100F, cooling rate will not be critical to formability. If you are heating above 1400F, then a slow cooling rate to around 1000 to 1100 will be required to avoid transformation to a hard martensite phase.
