surgical vs marine stainless steel

Any of those designations are worthless unless they specifically state the steel type. Even among the "stainless steel" types there are many different ones which differ in material composition and corrosion resistance.
I would suspect that most razors are made from either a 304 type (cheaper) or a 316 type (better, but more expensive). But both offer quite good corrosion resistance in day-to-day use.
That being said, for high-end razors the material cost is probably not really a factor.

Some say 316L is superior.
Common grades for razors are 303, 304 and 316(L)
Blades can be anything from Sandvik 13c26 and everything in-between...

“Marine grade” stainless steel refers to 316L. I believe “surgical grade” stainless is less defined, but generally refers to 316, 17-4, 440, and I think a couple others in the 400-series.
All I can offer is that pocket knives with "surgical stainless steel" are often of lower quality. If you think about it surgical tools don't really have to have high durability. They need to be highly resistant to rusting, and especially so if they go in an autoclave for reuse. Pockets of rust would be a hiding place for germs.
Great answer!
Doubt that there is much practical difference in razor durability or performance for the typical end-user.
Any SS razor will last longer than I will!!
Austenitic stainless steel grades can
not hold an edge .Thus ,straight razors
made of “ surgical grade “ stainless steel are most probably made with
martensitic or ferritic grades ,
like the 440 ( A,B,C & F ) or the
softer 420 .

Marine grade steel has higher corrosion resistance, not really important with razors, more of a buzz word.
If you are shaving on a desert island with little fresh water it might matter.
