A method and apparatus for a non-heat treated, high tensile strength, highly formable steel strap that may be applied in a tensioned loop about packaged articles with a strapping machine. The strap is fabricated from a steel comprising approximately, 0.20 to 0.25 percent carbon, 0.30 to 0.60 percent manganese, 0.04 percent maximum phosphorus, 0.05 percent maximum sulfur, an aluminum in an amount sufficient for full aluminum kill, 0.10 percent maximum silicon, and a boron to free nitrogen ratio of approximately between 1.07 to 1.43. The steel is coiled at a coiling temperature of approximately 1100 degrees Fahrenheit to reduce self-annealing that occurs during air cooling after coiling. The coiled steel is then reduced approximately 80 percent by cold rolling to increase tensile strength before it is fabricated into steel strap which may be protected with a zinc coating.
