Abstract

Cryogenic mechanical properties of a heavy-section weldment of high-manganese austenitic steel for the structure of superconducting magnet were evaluated. The heavy-section weld joint with a 200 mm thickness was manufactured by gas tungsten arc welding (GTAW) process using 21Mn-13Cr-5Ni-0.2N-B steel weld material. No cracks were observed in the weld metal. Tensile property and fracture toughness were tested at 4 K. The yield strength and the fracture toughness value, KIC(J), were 1223 ~ 1278 MPa and 181 – 201 MPam1/2 in the weld metal, respectively.
