上限をｏ、ｏｏｇ。S is used to improve the shape of the MIG welding bead, stabilize the welding arc, and reduce the amount of spatter.
0.0010% or more is added in order to generate MnS and prevent coarsening of crystal grains when heated to hot working temperature. Excess addition increases the amount of slag formed on the bead and increases the working time for its removal, so the upper limit is set to o, oog.

５％に限定した。O is normally an undesirable element and is reduced as much as possible, but in the present invention, it is used to stabilize the MIG welding arc and to reduce T.
In order to generate i, Zr oxides and to refine the crystal grains of the welded part, o, ooao% or more is contained, but excessive inclusion deteriorates the ductility of the welded part, so the upper limit is set to 0.01.
It was limited to 5%.

％に限定した。また、ＡＮ １５＋ （Ｍｇ ＋Ｃａ

。Ag, Mg, Ca, and REM are strong oxide-forming elements, forming oxides with high melting points, and causing a large amount of spatter and arc disturbance as the oxides dissociate during welding. Moreover, the height of the weld bead and the narrowing of its width simultaneously make the depth of the welding part shallow, which has a significant negative effect on welding workability. For this reason, the upper limit of each element content is Ap≦
0.0050%, Mg, Ca, REM≦0.0020
%. Also, AN 15+ (Mg +Ca
+REM)/2(7) The upper limit was limited to 0.0030%.

０％に限定した。Ti and Zr form fine oxides and carbonitrides in the MIG weld, and Nb + Ta forms carbonitrides to prevent grain coarsening and improve the ductility of the weld. Therefore, individually, T
i, Zr, Nb, and Ta in a total amount of 0.10% or more. However, when added in excess, the effect of preventing crystal grain coarsening in the weld zone and the effect of improving ductility are saturated, and the effect of increasing the amount added is lost. In addition, the upper limit for each element alone or in combination has been set at 0.6, as it significantly deteriorates MIG welding workability.
It was limited to 0%.

It can be applied to the ferrite type described in 21). In addition, ferritic stainless steel containing high Mn, high N, V, and B alone or in combination for high strength, and 20% or more Cr or 10% or less Mo for high corrosion resistance.
