Standard Specification for Tin Mill Products, Black Plate, Double Reduced

Abstract

This specification covers doubled-reduced black plate tin mill products produced from low-carbon cold-reduced steel, furnished in coils and cut sizes, for use predominantly in the manufacture of containers. The product, which is normally supplied with trimmed edges, may be specified "as rolled," without the removal of the rolling solution, and with no additional surface or oiling treatment, or "cleaned" with the rolling solution removed, with or without surface treatment and oiling. The rolling direction must be specified on cut lengths and will be indicated by underlining the slit (rolling width) dimension. Surfaces may polished in either the ground roll finish (base metal finish), or smooth finish with grit lines (7C finish).
