Properties
A-11 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
Typical Uses

Oil Hardening Drill Rod Tool Steel
O-1 Drill rod is one of the most widely selected grades of drill rod. It is precision ground which saves time and money in part making. It is made from grade O-1, an oil-hardening, non-deforming general tool steel. Tools and dies made from grade O1 will have good wearing qualities since the tungsten and higher chromium content gives improved wear resistance over the straight manganese grades.
Benefits of O-1 Drill Rod
- Can be hardened at lower temperatures
- Good wear resistance
