压力容器研究委员会选择了六种代表三种强度等级的高强度钢进行广泛的机械试验，以确定它们是否适用于设计应力增加的压力容器。本文回顾了利哈伊大学、芝加哥桥和铁公司、伊利诺伊大学和综合理工学校的调查结果。根据室温和高温拉伸试验、未焊接和焊接的缺口韧性、塑性疲劳和标准焊接评定试验，对这六种钢进行了比较。总的来说，这些钢的性能比碳钢要好。

The Pressure Vessel Research Committee selected six high-strength steels representing three strength levels for extensive mechanical tests in order to determine their suitability for use in pressure vessels with increased design stresses. This paper reviews the results of investigations at Lehigh University, Chicago Bridge and Iron Company, University of Illinois, and Ecole Polytechnique. These six steels have been compared on the basis of room- and elevated-temperature tension tests, notch-toughness unwelded and welded, plastic fatigue, and standard weld qualification tests. In general, the properties of these steels compare favorably with those of carbon steels.
