Machining 316 Stainless - Practical Machinist

Mar 19, 2010 · Machining 316 Stainless ??? It has been many years since I have ran 316 stainless steel. I have forgotten what it machines like and I have a few jobs to quote (and don't want to get burned) and wondered if anyone can give me a heads up to what I should expect.7 Things to Consider When Choosing a Stainless Steel Aug 22, 2016 · Very high strengths can be achieved with martensitic stainless steels, like grade 440C; and precipitation hardened stainless steels, like grades 17-4 PH and 15-5 PH. Austenitic stainless steels, such as grade 316, can provide high strengths as well, though not as high as the martensitic grades.TABLE OF CONTENTS MACHINING OPERATIONS AISI 1117 steel both have a hardness of 150 Bhn, their recommended cutting speeds for high-speed steel tools will be 140 fpm and 130 fpm, respectively. In some metals, two entirely different microstructures can produce the same hardness.

Speeds and feeds for drilling and reaming stainless steels

Traditionally high speed steel (HSS) tools have been used for drilling and reaming, but carbide tipped tools are also used for specialised jobs or long production runs.
