Stainless and Nickel Alloy Machining - Rolled Alloys, Inc.

Stainless and Nickel Alloy Machining. In general terms, machining stainless and nickel alloys is more difficult than machining low alloy steels. However, there are a wide range of stainless alloy compositions and a few of them (such as 416) can actually have better machinability than mild steel. The austenitic 300 series stainless steels like ...

Nickel and Nickel Alloys- Machining - espimetals.com

In reaming nickel alloys, sufficient stock must be removed so that nonwork-hardened or non-glazed material is being cut. Good starting points for stock removal are 0.010" for a ¼" hole, 0.015" for ½" hole, and up to 0.025" for a 1½" hole. Reamers must be kept sharp. Honed reamers produce smoother surfaces and last longer between grinds.

In the milling stage, there was a loss of 29.48 g, equivalent to 7.05 wt.% of the total mass fed on the hammer mill. This loss occurred due to the retention of comminuted material within the mill. However, it would be minimized in a continuous process, since a further loss would not occur after the internal spaces become filled with particles.
