抄録

In order to give 17Cr-4Ni-4Cu type stainless steels both strength and corrosion resistance by cold-rolling and age-hardening, the authors studied the effect of C addition up to 0.10% on the properties of the steels and the effect of Cu content up to 6% to the steels containing 0.17%N using dilatometric, hardness and metallographic examinations and corrosion tests. With increase of C and Cu contents the Ms temperature was lowered, the amount of the retained austenite was increased and the aging characteristics was enhanced. The effect on the aging characteristics was significant, particularly in the cold-rolled state. It was concluded that the addition of about 4% of Cu to the steel containing 0.17%N gives the best results after cold rolling followed by the aging treatment at about 440°C, and that the addition of C deteriorates remarkably the antisulphuric acid property, though this increases the hardness of the steel after rolling and aging.
