Respectfully, doesn't have to be ferrous.
When using a fire steel, the striker can be stainless (The backs of Falkniven's are famously good, being designed with that use in mind.).
Anything hard and sharp works. Steel works. Sharp edges of glass, flint, or porcelain all work . (I have used all three.) Brass, copper and aluminum are probably not hard enough. Ti also probably too soft.
Some cheap SS knives can be too soft, but usually their spines are just not sharp enough (You can try dressing them by passing back-and-forth against a file or flat sharpening "stone" until they have sharp edges.).
Hacksaw blades are a consensus good choice and can even be sharpened to be a back-up cutter. Saber saw blades are good.
Now if you want to strike a spark from steel with flint, SS is no good. Knife-hard carbon steel is the thing for that operation.
