Fracture Characteristics of Structural Steels: Reference Manual

Abstract

This report presents the findings of a scanning electron microscope (SEM) study of tensile, fatigue, and impact fracture characteristics of structural steels used in Army Corps of Engineers facilities and components. Steels investigated were ASTM A-36, ASTM A-514 AX-110 weld, HY-130, ASTM A-588, ASTM A-242, AISI 416, 17-4 PH, ASTM A-516, and ASTM A-607. Specimens were tested in as-received, hydrogen-embrittled, and temper-embrittled conditions. The failure mode of embrittled and unembrittled AX-110 weldments containing induced weld defects was also studied. The information contained in this reference manual will provide a basis for comparison of fracture characteristics to determine the mode of failure in analysis of components failure. Four examples of inservice failures in which the SEM provided valuable information are also presented. (Author)
