摘要： PURPOSE:To contrive the rationization of working stages, the reduction of cost and the improvement of characteristics by subjecting a high-Cr ferrite steel which contains specific compsn. ratios of C and Cr and is added with a specific ratio of Mo or W to specific hot working then to rapid cooling and tempering treatment. CONSTITUTION:The high-Cr ferrite steel which contains 0.03-0.3wt.% C, 5-13% Cr, and is further added with 0.1-3% total of 1 or 2 kinds of Mo and W which are solid-soln. strengthening elements is subjected to the hot working. The steel is heated to and held for >=1min at 900-1,300 deg.C and is hot worked in the final hot working. The carbonitride in the stock is thereby solutionized and the alloy components are uniformized, by which a normalizing treatment is omitted. The hot worked steel is quickly cooled at >=500 deg.C/h to convert the structure to martensite. The steel is thereafter subjected to a tempering treatment at the AC1 point or below to stabilize the structure. The steel is finished at need by warm working at the AC1 point or below. The working of the high-Cr ferrite steel having the excellent creep strength and high-temp. characteristics is thereby executed without the normalizing treatment.

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.
