A process for the production of a stainless steel strip having excellent spring characteristics as such and good formability, wherein a cold rolled strip of a stainless steel comprising, in addition to Fe, from 10.0 to 20.0 % by weight of Cr, from 0.01 to 0.15 o by weight of C, and at least one of Ni, Mn and Cu in an amount of from 0.1 to 4.0 % by weight, is continuously passed through a continuous heat treatment furnace where it is heated to a temperature range for a two-phase of ferrite and austenite, rapidly cooled to provide a strip of a duplex structure, consisting essentially of ferrite and martensite, optionally temper rolled at a rolling reduction of not more than %, and continuously passed through a continuous heat treatment furnace to effect aging of not longer than 10 minutes.
