Oxidation processing method of a ferritic heat-resistant steel

摘要

PROBLEM TO BE SOLVED: To provide an anti-oxidation treatment method for a ferritic heat resistant steel, which improves anti-oxidation property readily and economically.;SOLUTION: The anti-oxidation treatment method for a ferritic heat resistant steel includes a step where a chrome-containing ferritic heat resistant steel 3 is subjected to a heat treatment in a low oxygen partial pressure gas atmosphere 1 constituted of a mixture gas of CO₂ and N₂ to form a chrome-containing oxide coating 2 on a surface of the heat resistant steel 3.;COPYRIGHT: (C)2013,JPO&INPIT
