摘要： An iron based hardfacing alloy with an undiluted (all weld material) alloy composition is substantially balanced in order to achieve an hypo-eutectic primary austenitic with secondary martensitic solidification mode. The alloy enables the deposition of substantially crack-free single layers of hardfacing onto industrial components without any post weld treatment. The hardfacing alloy is capable of withstanding abrasion of silicious earth particles when applied to industrial products, such as tool joints, stabilizers and casing and other tubulars used in oil and gas well drilling, and other industrial products.

摘要： Disclosed is a hardfacing alloy capable of withstanding service abrasion of the order of silicious earth particles and weldable on industrial products, such as tool joints and stabilizers used in oil and gas well drilling, and other industrial products. The hardfacing alloy has a low coefficient of friction resulting from excellent metal to metal resistance and significant reduction in industrial wear on industrial products, such as casing wear. Other embodiments of the invention include tool joints having the hardbanding alloy welded to the outer cylindrical surface to its box and pin members and to stabilizer ribs on the stabilizer used in earth boring, such as boring for oil and gas, other industrial products, and methods of applying the hardfacing alloy to their surfaces. The hardfacing alloy does not require any post weld treatment, has primary borides in its microstructure, the carbons in the alloy are tied up in the formation of secondary carbides which add to the abrasion resistance, and have a quadratic crystallographic structure and a hardness of about 1725 Hv comparable to the prior art hardness of the chromium carbide primary carbide alloys of the prior art but is substantially less brittle than C—Cr—Fe hardfacing alloys.

摘要： Disclosed is a hardfacing alloy capable of withstanding abrasion of the order of silicious earth particles and weldable in crack free state on industrial products, such as tool joints and stabilizers used in oil and gas well drilling, and other industrial products. The hardfacing alloy has a low coefficient of friction, high abrasion resistance as welded without working, and in tool joints and stabilizers achieves an optimum balance between tool joint and stabilizer wear resistance and induced casing wear. Other embodiments of the invention include tool joints having the hardbanding alloy welded to the outer cylindrical surface to its box and pin members and to stabilizer ribs on the stabilizer used in earth boring, such as boring for oil and gas, other industrial products, methods of producing the hardfacing alloy, and methods of applying the hardfacing alloy to surfaces including preheat and post-welding conditions to withstand abrasive use.
