Abstract

The invention relates to an iron-based high-titanium wear-resistant surfacing flux-cored welding wire. Among a plurality of types of the prior wear-resistant surfacing welding wires and alloys, some alloys have favorable wearing resistance, and some alloys have great brittleness, lower toughness and easy cracking and are not suitable for the existence of low-impact grinding wear working condition.The iron-based high-titanium wear-resistant surfacing flux-cored welding wire comprises a low-carbon steel ladle clad and core powder as well as the following alloy elements in percentage by weight:1.0-3.0 C, 1.0-12.0 Ti, 0.5-9.0 V, 0.1-1.5 Si, 0.2-2.0 Mn, 0-3.0 B, 0.00-0.10 RE, 0-13.0 Cr, 0-1.0 Mo, 0-1.0 W, 0-2.0 Ni, 0-0.5 Nb and 0-0.5 Zr. The iron-based high-titanium wear-resistant surfacing flux-cored welding wire realizes the wear-resistant performance of the alloys mainly by carbides and borides formed by the alloy elements of C, Ti, V, and the like as well as a small amount of B element and adjusts the combination of the elements of C, Ti, V, Si, Mn, B, and the like to adjust the alloy hardness, enhance the toughness and lower the crack sensitivity.

Description

technical field

[0001] The invention belongs to the fields of machinery, iron and steel materials, etc., and in particular relates to a wear-resistant surfacing flux-cored welding wire for surfacing wear-resistant layers on the surface of steel tools. Background technique

[0002] There are many types of wear-resistant surfacing welding wires and alloys, some have good wear resistance, but some alloys are very brittle and have low toughness, so they are not suitable for abrasive wear conditions with low impact; some are suitable for abrasive wear with low impact The alloy of the working condition contains a lot of precious metals such as Nb, W, Cr, Ni, etc., and the cost is relatively high. For example, the Chinese patent wear-resistant surfacing alloy material (application number 200510043305.1) relates to a wear-resistant surfacing alloy material, and its alloy specific composition content (weight %) is: W 5-30, Nb 2-15, V 3-12, Mo 1-8, Cr 1-5, B 2-7, rare earth 0.01-2, t...
