PURPOSE:To provide a titled tube wire which is formulated to yield a build-up deposited metal having good wear resistance without delamination by specifying the component compsn. in a case and flux with respect to the entire part of the wire and limiting the amt. of the flux incorporated therein and the free carbon content in the flux. CONSTITUTION:The total of the component elements in a metallic case and the flux incorporated therein is specified to contain, by the entire weight of the wire, 2.0-5.0wt% C, 0.1-1.5% Si, 0.2-3.0% Mn, 15.0-28.0% Cr, 0.3-1.5% B, and further <=5.0% >=1 kind among Mo, V, Nb and Zr respectively. The amt. of the flux contained in the case by the entire weight of the wire is specified at 15- 60%, and the free carbon content in the flux at <=1.0% by the entire weight of the wire. The build-up deposited metal which is free from cracking, etc. and is hardly removable by delamination, etc. is obtd. by such high chromium ferrous tube wire for submerged arc welding. |
