HIGH STRENGTH STAINLESS STEEL FOIL FOR CORRUGATION AND METHOD OF MAKING SAID FOIL

摘要

With the application of final cold rolling to a stainless steel sheet containing from 10 to 40 wt % of Cr and from 1 to 10 wt % of Al as major constituents of alloy at the total rolling reduction of 75 % or more, or, if required, the application of aging treatment at a temperature ranging from 80 to 500 DEG C after completion of said final cold rolling, strength from 120 to 200 kgf at proof stress of 0.2%, and, when required, spring limit value of from 55 to 150 kgf/mm<2>, are imparted to a high strength stainless steel foil for corrugation process. Corrugation process at a working speed of 10 m/min or more is applicable.
