This is the blade I use for All my cutting but I think this Stainless is something different than just 304... It is HARD!!!!
I used a hacksaw to finish about an 1/8" that was left on one disc and it took forever and now That blade is dull

At least this is a one time thing. And you might know it was a freebie for my uncle.....
Northern is not what I would call a quality blade.
But if your material is hardened at all, you will have problems with any HSS blade. Be aware that a lot of stainless can work harden, too. You can try annealing it to see if that helps. There are also carbide coated blades that buzz through hard materials.
