GAS WELDING PORTION DUCTILITY IMPROVEMENT FOR UNSTABILIZED FERRITE TYPE STAINLESS STEEL COIL

摘要

After autogenous welding of coils of straight-chromium ferritic stainless steel, the weld area is heated to a temperature within the range of about 1325° to 1515° F. and water quenched from elevated temperatures to room temperature to improve the ductility of the weld area so that during subsequent cold rolling cracking of the weld area will be avoided.
