Special stripping chemicals

This specification covers hot-rolled and cold-rolled drawing alloy-steel sheet and strip. Material of this quality is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts. This steel is produced by a closely controlled steelmaking practice designed to assure internal soundness, relative uniformity of chemical composition, and freedom from injurious imperfections.
