SS904L is a superaustenitic grade. You can weld it directly to 304. No risk of low FN

--Dears,
We have one atmospheric hygienic (Food Industry) vertical vessel of SS904L material which is supported on legs. Vessel diameter is 3200 mm & TL-TL is 5100 mm.
The question is, can we weld SS304 directly on SS904L so that we can use SA-312 TP304 pipe l;eg supports?
Is it necessary to have SS904L RF pad instead of SS304?
Can there be an issue with weldability of SS904L with SS304?
Note : - We can't go for skirt support option.
