Summary

AUSTENITIC STAINLESS STEELS HAVE AN EXCELLENT COMBINATION OF MECHANICAL AND PHYSICAL PROPERTIES FOR LOAD-BEARING STRUCTURES OF LARGE SUPERCONDUCTING MAGNETS FOR PLASMA CONTAINMENT IN MAGNETIC FUSION EXPERIMENTS. TO ASSESS THEIR RELATIVE SUITABILITY FRACTURE TOUGHNESS, FATIGUE, CRACK GROWTH, AND TENSILE PROPERTIES DATA FOR FIVE AUSTENITIC STEELS AT 295, 76, AND 4 K HAVE BEEN OBTAINED. THE STEELS WERE AISI 304, 316, 304 LN, AND 316 LN, AND AN FE-21CR-12NI-5MN ALLOY WITH A HIGHER NITROGEN CONTENT THAN THE OTHER FOUR GRADES. THE TWO PRINCIPAL FINDINGS WERE THE SYSTEMATIC VARIATION OF YIELD STRENGTH WITH NITROGEN CONTENT AND A SYSTEMATIC INVERSE CORRELATION BETWEEN FRACTURE TOUGHNESS AND YIELD STRENGTH. DATA FROM PREVIOUS STUDIES ARE REVIEWED WHICH CONFIRM THE TRENDS OF THE PRESENT DATA.
