The advent of high-strength, low-alloy (HSLA) steels brought about a significant leap in performance. These alloys offered improved resistance to corrosion, higher yield strength, and better toughness, allowing drill rods to withstand the rigors of deep drilling without failing. Furthermore, heat treatment processes were refined to give the steel additional hardness while retaining its flexibility, ensuring that the rods could bend without breaking as they navigated through twists and turns in the mine shaft.
