Yes,,it's the right choice... Also,certain weld joint configs can have cracking issues that I have encountered in the past. When tested, the centerlined cracked welds had extremely low Ferrite levels(less than 3). I ended up solving that issue by welding with ER-312, which yields very high Ferrite levels. (20-30) and took the cracking issue away. So, just in case you mayencounter some centerline cracking,,that may be an idea for you as well.
