A stainless-steel welding wire for use in manufacture of an LNG tank is described. From the welding wire, it is possible to obtain a weld metal having excellent tensile strength and impact value because the contents of Ni, Mn, Mo, and Cr in the welding wire are adjusted. The welding wire can be applied to welding of all of 9% nickel steel, high manganese steel, and stainless-steel materials by adjusting the content relationship of Ni, Mn, Mo, and Cr, and has the effect of obtaining a weld metal with excellent ultra-low temperature toughness in the weld zone.

A cutting member for a saw chain and a method for the production thereof, the cutting member comprising a support part made of a steel alloy and a cutting part welded to the support part along a welding connection made of a high speed steel. The steel alloy of the support part is a tool steel that has the following composition (specifications in % by weight):

TABLE-US-00001 Carbon (C) 0.4 to 1.0 Silicon (Si) up to 1.8 Manganese (Mn) up to 0.6 Chromium (Cr) 4.5 to 12 Molybdenum (Mo) up to 3 Vanadium (V) up to 2
Iron (Fe) and accompany elements caused by melting and impurities as the remainder. The steel alloy of the support part in a quenched and tempered state has a hardness of more than 600 HV and a tensile strength of more than 2000 MPa as a result of curing at a suitable temperature above the austenitizing temperature of the high speed steel.

Disclosed herein are embodiments of a powder feedstock, such as for bulk welding, which can produce welds. The powder feedstock can include high levels of boron, and may be improved over previously used cored wires. Coatings can be formed from the powder feedstock which may have high hardness in certain embodiments, and low mass loss under ASTM standards.

A tailored welded blank produced from at least two blank parts, where at least one is a press-hardenable manganese-boron steel and at least one has a coating of aluminum or an aluminum-based alloy. The parts are welded by laser-beam welding or hybrid laser/gas-metal-arc welding, while retaining the coating, using shielding gas and a filler wire having in % by weight: C: 0.41 to 0.9; Si: 0.4 to 4; Mn: 0.4 to 3; optionally Cr: 0 to 10; and with optional alloying of one or more of: Mo: 0.01 to 1.0; B: 0.0008 to 0.0040; Ti: 2.5×B<=Ti<=5×B; V: 0.01 to 0.4; Nb: 0.01 to 0.2; W: 0.01 to 0.2; the remainder Fe and unavoidable impurities. The high proportion of C and Cr or additionally or alternatively of Mo, V, Nb and/or W enables hardening by carbide formation in a weld-seam region after welding.

Embodiments of an alloy that can be resistant to cracking. In some embodiments, the alloy can be advantageous for use as a hardfacing alloys, in both a diluted and undiluted state. Certain microstructural, thermodynamic, and performance criteria can be met by embodiments of the alloys that may make them advantageous for hardfacing.

The invention relates generally to welding and, more specifically, to corrosion resistant weld deposits created during arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). A disclosed corrosion resistant weld deposit comprises nickel, chromium, and copper, and has a low porosity.

Embodiments disclosed herein relate to the production of bulk amorphous metal (BAM) alloys comprising chromium, manganese, molybdenum, tungsten, silicon, carbon, boron, and the balance of iron to replace tungsten carbide-based welded material. The BAM alloy embodied herein can be applied through PTA welding, HVOF, TWAS, flame spraying, plasma spraying, laser, their combinations, and other coating and welding processes. When used as welded material, the density of the embodiment of around 7 grams per CC, which is less dense than the tungsten carbide customarily used, resulting in even hard faces during welding spread uniformly across the weld, therefore creating a harder and more wear-resistant weld.

A gas turbine engine component may include a coating adapted to protect the component during use. The coating may be applied by sintering metallic particles to form a metallic matrix fused to the component.

Disclosed herein are embodiments of wear resistant alloys, such as ferrous alloys, that can have reduced carbide contents. In some embodiments, the alloys may have no carbides. In some, the alloy may have boride phases, such as phases having high Mo+W content and/or high Fe+Cr content. There can be reduced hardphases levels out of the specifically disclosed boride phases in some embodiments. In some embodiments, hypereutectic chromium borides can have limited incorporation into the disclosed alloys.
