Description
High-strength nonmagnetic stainless steel suitable for cryogenic services, mainly as material of collars and beam tubes of superconducting super collider (SSC) magnets, was developed using 10Mn-19Cr-6Ni steel as the base material. The carbon content should preferably be high for strength, but if it is too high, carbide precipitates and toughness is impaired. Permeability at a cryogenic temperature shows good correspondence with Neel temperature. Although Ni reduction and Mn addition are effective for nonmagnetization, excessive Mn decreases the coefficient of thermal expansion. The precipitation of δ-Fe in the spot welds should be prevented to nonmagnetize, and for this purpose, composition adjustment is necessary so that the value of δ-Fe calculated using Hull's equation will be below zero. Based on the results in this study, 0.09C-10Mn-19Cr-6Ni-0.35N steel was selected as a steel of optimum composition, and was trial-produced by a commercial process
