That 303 stainless can be forged but it takes some doing. I can across a 1" round bar last year. Get it very hot and it will let you know when it's too cool. Also from what I've read it's a air hardening steel so don't bother heat treatment. I made small very rough looking Hardie cutoff out of it and it held up quite well. Just don't miss or you will ding up your hammer.
Might be good for eating utensils.
