A method is disclosed for prevention nitridation or carburization of metal surfaces in contact with a fluid including nitriding agents or carburizing agents where the method involves adding to the fluid an effective amount a sulfur-containing compound and a phosphorus compound, where the amount of phosphorus-containing compound is less than the amount of sulfur-containing compound. The simultaneous addition of both a sulfur compound and a phosphorus compound prevents nitridation and/or carburization and sulfidation of the metal surfaces in contact with fluids containing nitriding and/or carburizing agents significantly increasing the metal's lifetime. |
