Abstract
The Sub-commitee on Mechanical Properties of the JPVRC-Elevated Temperature Design Committee (J-ETD) surveyed several material data bases on typical high temperature resistant steels to contribute to future establishment of the material strength codes or standards, which will be utilized under the simplified procedures for design and structural serviceability assessment for non-nuclear pressure vessels. Several accessible data bases, issued by public institutes, research councils and committees etc., are already available or will be available in the near future. But those data bases are not necessarily sufficient to establish the material strength codes or standards by themselves. Consolidation of several data bases and further acquisition of insufficient data, especially on creep deformation and creep-fatigue properties into the data bases, are required to prepare for establishment of the material strength codes and standards. Data bases on weldment properties will be also needed.
