Machining of Hastalloy

Machining of Hastalloy

Machining of Hastalloy

(OP)
Does anyone have any experience machining Hastalloy?

if so what Surface speed and depth of cuts are best?
 

RE: Machining of Hastalloy

You need to down load this booklet from Haynes and check page 35.

The real bugaboo with HastC is that it work hardens and is extremely wear resistant. Keep everything sharp on rigid equipment.

RE: Machining of Hastalloy

I had very, very poor luck simply drilling Hastalloy X last year until I really slowed down the drill bit and used a little bit less pressure.

But for the number of holes I needed, I found a hand-held electric punch worked very simple, very fast, and was simplest of all.   

Doesn't help you with machining, but I figure I'll throw my 2 cents in.
