More than likely it will be 303 or 316. 316 iis the tougher one and you will need a sharp tool to cut it. the 303 is softer and much easier to machine. I use HSS tools and it works fine with a bit of coolant.

300 series stainless steels are non-magnetic, or virtually so, which allows for a simple test. They machine readily to a good finish but work-harden. Modest speeds but relatively high feed-rates and DOC avoid this. Also applies to drilling. Don't let the tool rub. For myself, I'd probably use HSS tool-bits, a sharp tool is needed.
