The above materials is used for LPG service (in spherical tank ) with the design condition is:
Temp. Operation/Design: 28/-10deg.C

Choosing Cl2 grade would save on materials(lower design thickness due to higher Y.S and UTS). However welding consumables with 80 Ksi nominal UTS would be required to match the base metal strength,after PWHT.
PWHT would be must for 57 mm wall thickness.
Thanks.
