日本电力工程和检查公司组织了一个委员会，以评估长期蠕变强度，并审查目前的许用拉伸应力的蠕变强度增强铁素体钢。2005年度，对经济产业省火力发电标准规范中KA-STPA 29（ASME Gr.92）、KA-STPA 24 J1（ASME Gr.23）和KA-SUS 410 J2 TB钢的许用拉应力进行了审查。用区域分裂法对这些材料的蠕变断裂数据进行了分析，其方法与对改进的9 Cr-1 Mo钢（ASMEGr.91）和KA-SUS 410 J3钢（ASMEGr.122）的分析方法相似。结果表明，KA-STPA 29钢和KA-SUS 410 J2 TB钢在蠕变状态下的许用拉应力应修正为较低的值。
A committee at Japan Power Engineering and Inspection Corporation was organized to evaluate long-term creep strength and to review current allowable tensile stress of creep strength enhanced ferritic steels. In FY2005, allowable tensile stresses of KA-STPA29 type steels (ASME Gr.92), KA-STPA24J1 type steels (ASME Gr.23) and KA-SUS410J2TB steel regulated in METI (Ministry of Economy, Trade and Industry) Thermal Power Standard Code has been reviewed. Creep rupture data of those materials have been analyzed by means of region splitting method in a similar way to that applied for a previous review on a modified 9Cr-1Mo steel (ASME Gr.91) and KA-SUS410J3 type steels (ASME Gr.122). It has been concluded that the allowable tensile stresses in a creep regime of KA-STPA29 type steels and KA-SUS410J2TB steel should be revised to the lower values.Copyright © 2006 by ASME
