摘要： PURPOSE:To improve the creep strength of the titled steel contg. V and Nb after the lapse of a long time at a high temp. by selecting a composition for the steel so as to regulate the AC1 transformation point to a prescribed value and by carrying out tempering at a high temp. CONSTITUTION:A composition is selected for a ferritic steel so as to regulate the AC1 transformation point defined by the formula to >=820 deg.C. For example, a ferritic steel contg., by weight, =820 deg.C AC1 transformation point is used. The steel is normalized at the AC3 transformation point or above and tempered at 810- the AC1 transformation point.
