The choice of drill rod steel is crucial due to the harsh conditions it encounters. It needs to be strong enough to resist bending and breaking under immense pressure, while also being resilient against wear and tear caused by friction and abrasive materials. Typically, drill rod steel is composed of high-carbon alloy steels, often containing elements like manganese, chromium, and nickel to enhance strength, toughness, and resistance to corrosion.

...

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.
