201 or 202 Stainless steel

[Neal Z]

I had posted this question in off topic with little response. Suggestion was made to move over here. So.... Has anyone used this material? I never heard of it before this week. It's available. Not sure what the one enginneer has in mind, but he asked if I had machined it before. Appericate your help.

I have never machined it but, my alloy ref. list

says the AMS# is 5553 and the Pratt Machinability rating is 60%

neal, from what i read about it ,it is used for making appliances and resturant equipment,used mainly for forming and rolling.it is suppose to be easy to clean and leaves fewer fingerprints.don't know

why someone would want to machine it.

"These grades may be a bit easier to machine than their 3XX counterparts because of the addition of manganese"

"A number of stainless steel alloys in this classification have the trade name Nitronic"

 

That should make it fairly easy to machine.

 

Another interesting fact: "These alloys were used during the Korean War to preserve nickel."

201 machines alot like 302 check with your cutting tool supplier to verify grade. Nose rad and chipbreak are important!

+1000 to cascade,

 

tool geo is very important with any stainless. We mostly cut alot of 3xx series (including 304L nuclear ). So when we get a 2xx series job, it's a treate . It is also important to do the math for your speeds, feeds, and DOC up front. Don't do the old WAG method.

 

Just my two cents.

Thanks for all the replies. I talked to my tool rep and he's doing some research on this stuff.
