Abstract
The character of variations in phase composition of the 10Kh9MFB type weld metal depending upon its carbon content was analysed. It was found that single-phase martensitic structure of the welds could be provided at their carbon content of not less than 0.085 %. Decreasing the carbon content below the above limit leads to formation of δ-ferrite in structure of the welds.
