Patent ID: 8574381

Claim:
A weld metal, comprising Fe, and, by weight %: C: 0.04 to 0.15%; Si: 0.50% or less, not including 0%; Mn: 1.0 to 1.8%; Ni: 1.0 to 4.0%; Cr: 0.10 to 1.0%; Mo: 0.20 to 1.2%; Ti: 0.010 to 0.060%; Al: 0.030% or less, not including 0%; O: 0.015 to 0.060%; and N: 0.005 to 0.010%; wherein, a mass ratio of [compound Ti]/[compound Si] is more than 1.5, wherein the ratio reflects the amount of Ti oxides present to the amount of Si oxides present obtained by electrolytic extraction, a number A is 0.50 or more, and satisfies: A =[Ti]/([O]−1.1×[Al]+0.05×[Si]), wherein [Ti], [O], [Al], and [Si] are a content of each element by weight %, and an average size of carbide particles with a circle equivalent diameter of 200 nm or more in the weld metal is 350 nm or less.
