Abstract
The present disclosure relates to an alloy, for hardbanding and/or hard overlay applications, which is abrasion resistant to the order of siliceous earth particles and weldable in crack free state on industrial products. The alloy is a carbon chrome based alloy comprising titanium and vanadium carbides and thus has an extremely low coefficient of friction, high abrasion resistance as welded without working. In tool joints and stabilizers, the alloy achieves an optimum balance between tool joint and stabilizer wear resistance and induced casing wear. The alloy is also self-shielded and therefore does not require external shielding gas.
Claims16
A hardbanding alloy, comprising by weight:
- about 2.4% vanadium;
- about 4% titanium;
- about 1.2% manganese;
- about 0.5% to about 1% nickel;
- about 5.0% to about 7% chromium;
- and
- about 0.8% molybdenum,
- wherein the hardbanding alloy is formed as a self-shielded, metal-cored, open arc welding wire, and wherein the hardbanding alloy is to be applied as a weld deposit to a surface to produce a wear resistant overlay on the surface.
A hardbanding material comprising:
- a carbon chrome based alloy having vanadium carbide granules and titanium carbide granules;
- wherein the alloy comprises, by weight, about 2.4% vanadium, about 4% titanium, about 1.2% manganese, about 0.5% to about 1% nickel, about 5.0% to about 7% chromium, and about 0.8% molybdenum;
- wherein the alloy is formed as a self-shielded, metal-cored, open arc welding wire, and wherein the alloy is to be applied as a weld deposit to a surface of a base material to produce a wear resistant overlay on the surface of the base material.
A welded component, comprising:
- a surface;
- a wear resistant overlay which is applied to the surface and includes at least one weld deposit, wherein the at least one weld deposit is produced from a hardbanding alloy which is formed as a self-shielded, metal-cored, open arc welding wire, and wherein the at least one weld deposit comprises, by weight:
- about 2.4% vanadium;
- about 4% titanium;
- about 1.2% manganese;
- about 0.5% to about 1% nickel;
- about 5.0% to about 7% chromium;
- and
- about 0.8% molybdenum.
