DRAWABILITY OF DEOXIDIZED STEELS BY THE ADDITION OF PHOSPHORUS AND SILICON

摘要

SPECIFICATION DAVID C. LUDWIGSON IMPROVING THE DRAWABILITY OF DEOXIDIZED STEELS BY THE ADDITION OF PHOSPHORUS AND SILICON The high drawability of deoxidized steels with Mn contents below about 0.22% is enhanced by the addition of from about 0.015 to 0.05% P. The beneficial effect of such phosphorus additions on drawability is further enhanced by employing from about 0.02 to 0,05% Si.
