Steam Service Piping Material <150 PSIG 1

[NCENG78]

Currently my company uses ASTM A53 Grade A for all steam and condensate service. Our main boiler pressure is 130 PSIG. Can someone help explain to me why you would use one or the other and if ASTM A53 Grade A or B is acceptable for my application? My previous company use ASTM A106 for steam and condensate at 130 PSIG steam.
