Method of making deep drawing stainless steel

Claim 1

THE METHOD OF MAKING DEEP DRAWING QUALITY COLD ROLLED, 14, TO 23 STAIGHT CHLOMIUM TRANSFORMING, STAINLES STEEL STRIP CAPABLE OF BEING DEEP DRAWN WITH A MINIMUM OF DERECTIONAL LINEA IMPARTED BE DIRECTIONAL HOT ROLLING OF THE DALTA AND GAMMAN IRON PHASES WHICH EXIST AT HOT ROLLING TEMPERATURE BUT NOT AT ROOM TEMPERATURE IN 14% TO 23% STRAIGHT CHROMIUM TRANSFORMING STAINLESS STEEL STRIP CAPABLE OF BEING DEEP DRAWN WITH A TRANSFORM UPON COOLING TO A DULPEX STRUCTURE CONSISTING OF FERRITE SUBSTANTIALLY ORIGINATING FROM THE DELTA IRON PHASSE AND A DECOMPOSITION PRODUCT ORIGINATING FROM THE GAMMA IRON PHASE ARRANGED IN A CLUSTER OF SMALL BANDS RUNNING IN THE DIRECTION OF ROLLING THE STEPS OF HOT ROLLING SLABS OF 14% TO 23% STRAIGHR CHLOMIUM, TRANSFORMING, STAINLESS STEEL AT HOT ROLLING TEMPERATURE OF FROM ABOUT 2300* F. TO 1600* F. IN ONE DIRECTION TO FROM HOT ROLLED STRIP; CONTINUOUSLY HEATING THE HOT ROLLED STRIP TO A TEMPERATURE IN THR RANGE OF FROM 1700* F. TO 2100* F. FOR FROM ONE TO TEN MINUTE TO PROMOTE A REDISTRINUTION NETWEEN THE GAMMA AND DELTA PHASE IN A TEMPERATURE RANGE WHERE THEY COEXIS AND IN THE ABSENCE OF MECHANCAL STRESS, TO EFFECT A BREAKUP OF THE BANDED STRUCTURE AND TO REDISTRIBUTE, RESPHE AND CONVERT THE GRAINS WHICH ARE APPROXIMATELY POLYGONAL PRIMS AFTER A HOT ROLLING INTO IRREGULAR POLYHEDDRONS OF MANY FACES TENDING TO APPROACH A SPHERICAL SHAPE UPON COOLING; THEN ANNEALING THE STRIP AT FROM 1400*F. TO 1650*F., THEN COLD ROLLING THE STRIP TO DESIRE GAUGE, AND THEN CONTINUOUSLY ANNEALING THE COLD ROOLED STRIP AT A TEMPERATUR BETWEEN 1350* F. AND 1500* F. TO PROVIDE ANNEALED COLD ROOLED STAINLESS STEEL STRIP METERIAL HAVING ELONGATION OF ABOUT 30% IN TWO INCHES.
