Abstract

The invention discloses a wear-resistant flux-cored wire for stainless steel. The wear-resistant flux-cored wire consists of a flux core and a stainless steel sheath coating the outer side of the flux core, wherein the flux core comprises the following raw materials in parts by weight: 15-22 parts of chromium powder, 1-4 parts of titanium powder, 0.5-2 parts of nickel powder, 1-4 parts of silicon calcium alloy, 1-4 parts of magnalium, 4.5-7 parts of ferromanganese, 2-5 parts of ferromolybdenum, 2-4 parts of ferrocolumbium, 4-8 parts of rare earth ferroalloy, 4-8 parts of vanadium-nitrogen alloy, 6-9 parts of carbonate, 3-6 parts of graphite and 100-150 parts of iron powder. The wear-resistant flux-cored wire for stainless steel has favorable wear resistance, corrosion resistance, heat resistance and mechanical property; a deposited metal structure is compact, pore-free and crack-free; and the wear-resistant flux-cored wire for stainless steel can be favorably combined with a base material and is stable in performance.

Description

technical field [0001] The invention relates to the field of welding wire technology, in particular to a wear-resistant flux-cored welding wire for stainless steel. Background technique [0002] Flux-cored wire is a new type of welding material that has developed rapidly in recent years. Flux-cored wire is widely used in aerospace, automobile manufacturing, construction, bridges, petrochemical and other fields. The welding quality and welding efficiency are determined by the welding materials and welding process, especially the welding materials are the key to welding. At present, the stainless steel flux-cored welding wire still has unreasonable composition configuration, which leads to small pores and cracks in the deposited metal. , At the same time, it needs to be improved in terms of wear resistance, corrosion resistance, heat resistance and mechanical properties. Contents of the invention [0003] Based on the technical problems existing in the background technology...
