Abstract
There is disclosed a method for preparing nominally 13% chromium-0.3% columbium ferritic stainless steel by producing the steel to have very low content of residuals, carbon and nitrogen, hot rolling the steel, annealing the hot rolled steel, and cold rolling the annealed material to reduce the thickness at least 65 percent.
