Yes, drill rod can easily be welded. However, proper welding practices should be followed as heat from the welding process will cause hardening.
Are drill rods weldable?
Oil hardened drill rods are easily welded and machined and are very tough and durable. During the oil hardening process, the rod is heated until glowing red then plunged into a vat of warm oil. This causes the surface to become extremely hard. Oil hardened drill rods are used for general tool making.
Can you thread drill rod?
Can drill rod be threaded or drilled with a standard die, tap, and HSS Drill Bit? Yes. It is normally shipped in the annealed state. It is workable with HSS tools.
What grade of steel is drill rod?
AISI A2 Tool Steel Drill Rod is an air-hardening tool steel that contains five percent (5%) chromium. The chromium in drill rod replaces the oil hardening (O1 type). A2 Drill Rod is ideal for applications where safer hardening, less distortion and increased wear-resistance are required.
Can you weld O1 tool steel?
O1 steels are weldable but run the risk of crack formation but this can be avoided with certain specifications. During welding of soft annealed O1 tool steel, the steel should be preheated to 300 – 500°C (572-932°F), welded at same temperature and finally the stress should be relieved immediately.
Can drill rod be hardened?
Drill rod stock is typically supplied without being heat treatment, or unhardened, so that it is easy to machine. Once the metal is machined into its tool form, it can be hardened through heat treatment and then drawn back.
What is the hardness of drill rod?
The rods are manufactured of annealed tool steel (O-1, A-2, D-2, H-13, S-7, M-2, or W-1). Then they are cold drawn and (usually) polished. The drill rod hardness is affected by the cold drawing manufacturing process.

What is the strongest steel rod?
In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
What is the difference between Rod and Bar?
is that bar is a solid, more or less rigid object with a uniform cross-section smaller than its length or bar can be a non-si unit of pressure equal to 100,000 pascals, approximately equal to atmospheric pressure at sea level while rod is a straight, round stick, shaft, bar, cane, or staff.
Is stainless steel rod strong?
Stainless steel threaded rod proves, when tested, to be stronger than most Grade 2 steels, but weaker than Grade 5 and Grade 8 stainless steel raw materials that have been hardened. Depending on the ratio of metals in the alloy, the definitive strength of most stainless steel grades will range from about 70 to 220 ksi.
