HEAT-TO-HEAT VARIATIONS OF TOTAL STRAIN (TO 5%) AT DISCRETE STRESS LEVELS IN TYPES 316 AND 304 STAINLESS STEEL FROM 24 TO 316°C

摘要

Tensile tests were conducted on eight heats of randomly selected, mill-annealed type 316 stainless steel and seven heats of mill-annealed type 304 stainless steel at 24, 93, 204, and 316°C to establish the effects of heat-to-heat variations on total strain (to 5%) at discrete stress levels. Factors of difference were established between maximum and average strain (corresponding to minimum and nominal yield strength material respectively) for regulatory analysis applications. Limited tests were conducted to show the effects of product form and material condition on total strain.
