为压力容器研究委员会材料部门编制的解释性报告；讨论可用材料的特性、设计规则、制造工艺和应用。 本文综述了特别适用于压力容器和某些化工及加工设备的铝合金的性能。铝合金能抵抗许多材料的化学作用，对于那些有某种作用的材料，其产物是无色的；因此，它们不会产生变色。它们还表现出显著的抗大气腐蚀性。铝合金是无磁性和不停车的。热传导率和电传导率相对较高。适用于压力容器的市售合金具有广泛的抗拉强度。ASTM规范B178中涵盖的十种板状合金- 54T在退火条件下具有规定的拉伸强度，范围为9500至30000 psi。铝合金与低碳钢一样，在温度降低时，延展性不会降低；事实上，所讨论的大多数合金的抗拉强度、屈服强度、延伸率和抗冲击性随着温度降低到-420°F而显著增加。它们易于加工，易于焊接。铝合金的使用记录非常令人满意。由于多年的实验和经验，领先的生产商已经发布了大量数据，并准备了手册，可以参考这些手册来回答具体问题。

An interpretive report prepared for the Materials Division of the Pressure Vessel Research Committee; discusses characteristics of materials available, design rules, fabrication processes and applications. This paper reviews the properties of the aluminum alloys that are especially desirable for pressure vessels and certain chemical and processing equipment. Aluminum alloys are resistant to the chemical action of many materials and, for those materials where there is some action, the resulting products are colorless; hence, they produce no discoloration. They also show remarkable resistance to atmospheric corrosion. Aluminum alloys are nonmagnetic and nonsparking. Conductivity ratings for heat and for electricity are relatively high. Commercially available alloys suitable for pressure vessels represent a wide range of tensile strength. Ten of the alloys in the form of plates covered by ASTM Specification B178-54T have specified tensile strengths in the annealed condition ranging from 9500 to 30,000 psi. Aluminum alloys do not show a decrease in ductility with depressed temperatures as does mild steel; in fact, the tensile strength, yield strength, elongation and impact resistance of most of the alloys discussed show a distinct increase as the temperature decreases to -420°F. They are readily workable and easily welded. The service record of aluminum alloys is outstandingly satisfactory. The leading producers have, as a result of many years of experimentation and experience, published much data and prepared handbooks that may be consulted for answers to specific questions.
