They do. Most of the Jackson Ultima blades use a strong stainless steel.
Any decent cheap high carbon steel can be made quite hard. "Stainless" (rust resistant) isn't always particularly strong.
For that matter, most of the blade shouldn't be too strong (which means brittle). Ideally, only the edge is hard - and even that is only about hardness level 60. For steel blades, flexibility, rather than ultimate hardness, is what helps a blade take jump landings without breaking.
When it comes to skate blades, a lot of blades over $100 or so are made of a good steel. Certainly by the $200 level, like MK Pro.
If I could find a reasonably priced stainless steel blade whose shape I liked, I would choose that - because stainless steel, like the re-hardened edge, requires less frequent sharpening. But for the moment, I have stayed with a good high carbon steel blade, plated (except for the bottom-most part, where the plating has been ground away to expose the hardened steel). So have a lot of - maybe most - skaters far better than me, as that describes most MK and Wilson blades.
MK/Wilson start with a fully hardened steel, cut it to shape, soften ["temper"] it, sharpen it, then partially re-harden the edge. At some point in the process [details are a trade secret] they plate it with nickel, then chrome on the most expensive blades [because it's shinier], and grind away the bottom plating. It is possible that most Reidell blades are made the same way.
Unconfirmed info is that MK/Wilson's more expensive "Revolution" blades are made of a titanium/steel stainless steel alloy, then plated for additional rust-resistance with titanium. And that Ultima blades are made of a chromium/steel stainless steel alloy, then plated with a hardened nickel alloy. But it all cases, the tempering/edge-rehardening cycle is the heart of any decent blade making process. Not just for skates, but for many good knives.
Anyway, we don't know your weight, but, since many skaters doing triples and quads get away with good steel blades, it is quite likely that you can you can too.
