A350 LF2 In Place of A105 - Material engineering general

Hi, Pipe Class and the data sheet for a ball valve calls for A105 Body material. Project department has procured A350 Lf2 material Ball valve and asking engineering to give some justification to show to client that it is superior and hence acceptable for the servie (oil line at amb. temperature) service and that guy happens to be me to give this technical justification.
