The shop I work at just finished cutting some stainless. I looked up the Heat Number and the certs and it is defined as 17-4PH H1150. Am I missing something? I thought 17 - 4PH is different than 17-4 H1150..

Anyways. I'm going to use the bar ends to turn out some shifters to mess around with some ideas, and I was wondering what cutting speed I need to use? And, will I be ok with using a G50 of 1800?

After turning, I'm planning on getting them chromed, or powder coated. So, what surface finish do I need to produce? Would a feed of .006 be ok, or do I need to go rougher?

And my last question... is it imperative that I use an insert specifically for stainless, or can I use a standard coated carbide for turning 4140 HTSR and get by with it?
