Abstract

A number of wrought and cast stainless steel alloys were used to evaluate the effect of Charpy V-notch striker radius (2 mm vs 8 mm). Standard 10 mm by 10 mm (and 5 mm by 10 mm for N06022) specimens were machined from 5 grades of wrought material (304, 309, 316, N08367 (more commonly known as AL-6XN¿ alloy), and N06022 (more commonly known as Alloy 22)) and one grade of cast material (CN-3MN, but in two heat treatments). Statistical analysis showed a small, but in some cases significant (p value of less than 0.05), difference in the data obtained from the two strikers.
