Abstract

FIELD: metallurgy. SUBSTANCE: method for producing strip for springs consists in that carbon steel strip 1.0-2.0 mm thick is subjected to isothermal hardening in lead bath or some other medium ensuring rapid cooling at 375-475 C to obtain structure of upper bainite. Then, strip is cold-rolled with total deformation above 80%. EFFECT: improved strip quality by increasing the number of bend-unbend up to failure and higher springing angle and increased strip material ultimate strength. 1 tbl
