Recently an increase in production cost of 300 series stainless steel with a sudden increase in nickel cost has caused a decrease in demand for 300 series stainless steel so that 400 series stainless steel has begun to make a mark. Although 400 series stainless steel has good properties, it has a problem of lack of corrosion resistance. There is Ti in 400 series stainless steel alloys to solve the problem above and it has lower density than the others. For that reason, wire feeding process has been applied for adding Ti alloy in 400 series stainless steel. This paper presents consideration of variation on the depth of wire dissolution by conditions of wire feeding which are wire injection speed, the temperature of molten steel, wire diameter and bubble generation rate. The computer program for solution of conducting wire feeding has been developed in Flow3D.
