What is 416ss like to machine?

[MrWhoopee]

actually love machining it.

That's not 304!

Look on google for Machinability chart. It will give you good idea of percent of machinability.

magnets wont stick to it. so am i probably cutting 316?

Something in the 3xx series. Assuming you're talking flat bar, 304 is most likely with 316 coming in a distant second depending on where it came from. 316 is the material of choice for better corrosion resistance, particularly acid exposure like tomato processing.

this is 2" round stock from a donut shop (dunkin or krispy cream)

Most likely 303 or 304. If you think it machines "fine", it's probably 303. 316 would be too expensive for donut shop applications where enhanced corrosion resistance is not required. It also does not machine nicely.

Thanks for the responses. Do understand I don't know what nice machining is, not really. I've milled cold rolled, and it's gummy, same with some random aluminum. This stuff is hard, but boy is it fun watching the chips fly. More than once I undercut a part because I was having so much fun cutting it .. ( ok, I know I sound like a real noob)

Are you sure you're a noob? That's a nice looking part there.

Thanks, even a broken watch is right twice a day.
Ok, so I have alot of hobby machine time, but I don't know, haven't tried to understand, why and how it works. I've just started trying to understand that. Up until now I've just been doing, and if something wasn't working I would do something else until I find a sweet spot, hence that part I pictured which has come out pretty well .. but I still don't really understand why it came out as good as it did. It's a highway peg for my motorcycle, we'll see how close I can make the second one..
