Wire rope is made from cold drawn strand. In the case of stainless the material's ultimate tensile strength increases from about 73ksi to about 197ksi through the drawing process. Heating the cable anneals it, returning it to it's unworked strength of about 73ksi, for a 63% reduction in strength. If you were using 3/32" stainless 7x19, you'd reduce the strength from 920# to about 341#.
