Nomar: The answer to your question depends on what type of steel you are referring to and how long it was exposed to the fire. David Hendrix The Hendrix Group Inc.

Nomar: The fire should not have degrated the A106 Gr. B pipe. The extent of matallurgical/mechanical changes to the 4140 would depend on the original heat treatment of the 4140 and if the component were quenched with water above the AC3 temperature. In another words, the fire could have softened the material or hardened it. You should condsider conducting hardness tests of the components exposed to the fire.
