ABSTRACT OF THE DISCLOSURE A drawing quality hot-dip coated low carbon aluminum killed steel strip produced by conventional steel strip forming and continuous hot-dip coating procedures wherein the hot rolled coiling temperature is maintained within a temperature range of 1250°F - 1300°F and the cold rolled steel strip is continuously heat treated on a Sendzimir-type continuous hot-dip coating line at a temperature of between 1850°F and 1950°F before cooling the strip to about the temperature of the hot-dip coating bath and immersing the strip in a hot-dip galvanizing or aluminum coating bath followed by conventional annealing. The micro- structure of the drawing quality hot-dip coated steel strip is characterized by spaced islands formed of fine pearlite and fine ferrite having a grain size of about ASTM 9-10 surrounded by areas of large ferrite grains having the grain size of about ASTM 7.5-8. A typical hot-dip coated drawing quality steel strip produced by the process has a Rockwell B hardness of about 47, an average lower yield strength of about 32 RSI and an average ultimate tensile strength of 50 RSI and an average total elongation percent in two inches of about 40 percent.
