We have a lean oil heating furnace with A-106b tubes. The approximate tube temperature (surface) is 750F. We have a haz-op item on this that says we need to verify that the tubes are not susceptible to carburization. Can someone lead me to a reference chart, or some other text to help me verify this. Thanks.
