Working on a special project. Need to source 304L from an uncommon source. ID of the 304L is 32mm. XCr is 31.7 OD. My question is about the gap. Can it be filled with Harris 45T?

There is a slightly smaller 304L ID option which is 31.62.

If it were you would you fill the gap with 45T or enlarge the ID of the 31.62?
