Abstract

The elements which are cold-formed from is not >7 mm thick sheet steel containing not more than 0.5% carbon, are hardened at a temp. higher than the critical temp. and close to a temp. for rapid transformation from austenite to martensite. Temp. is maintained for sufficient time for complete transformation and treated sheet is then cooled to ambient temp. Temp. may be between 150 and 470 degrees C and steel should contain over 0.5% Mn. Moderately high ductibility, high resistance to cracking and accurate dimensions can be obtained.
