cold rolled strip steel

DEFINITION a flat rolled steel over 1/2 inch in width not exceeding a carbon content of 0. 25 per cent by ladle analysts. It is produced to meet exacting and defined tolerances as to thickness, width, length and camber. Available In coils and flat lengths, and customarily described by designating a specific finish, temper and edge.

FINISHES
Finish refers to the degree of surface smoothness of the strip and is so classified

NO. 1 Dull FINISH-A matte finish, which is specifically made for better adherence of paint, die lubricant and other material of a similar nature.

NO. 2 BRIGHT FINISH-A luster finish which is made for those applications where the method of finishing requires an extra smooth surface

TEMPERS
Temper indicates the mechanical properties of hardness, strength, stiffness and ductility. It is classified by degree of Rockwell Hardness

NO. 1 TEMPER (full Hard)-Thickness 0.069 and thinner Rockwell B-90 minimum thickness 070 and heavier Rockwell B-84 minimum. This temper is not intended for Cold Forming.

NO. 2 TEMPER (Half Hard)-Rockwell B-7O minimum and B-85 maxi mum, approximately. This temper can be bent 90 degrees across the direction of rolling around a radius equal to its thickness.

NO. 3 TEMPER (Quarter Hard)-Rockwell B-6O minimum and B-75 maximum, approximately. This temper can be bent 180 degrees across the direction of rolling over one thickness of the strip and 90 degrees in the direction of rolling around a radius equal to its thickness.

NO. 4 TEMPER (Soft)-Rockwell B-65 maximum, approximately. This temper can be bent flat upon itself in any direction.

NO. 5 TEMPER (Dead Soft)-Rockwell B-55 maximum, approximately. This temper can be bent flat upon itself in any direction.

ALUMINUM KILLED QUALITY-Specified for those uses in which stretcher straining, fluting, or breakage due to aging of the steel is likely to occur
