METHOD OF PRODUCING STEEL ARTICLES Russian patent published in 1994 - IPC

Abstract RU 2015179 C1

FIELD: producing steel articles. SUBSTANCE: steel is affected by cold plastic deformation (its degree being 30-40%), processing by cutting to produce given shape and size of articles and by two-stepped ageing. The latter process takes place within 1-1.5 h at 530-550 C and within 4-4.5 h at 450± 10^°C 4-4,5. EFFECT: improves efficiency of the method. 1 tbl
