Machining Material 17-4PH
17-4PH (Alloy 630) is a Precipitation-Hardening stainless steel with 17% Chromium, 4% nickel, and 4% copper content. It is primarily used in the oil & gas and aerospace industries, where a combination of high strength and corrosion resistance is critical.
17-4PH is supplied in several conditions that differ in their hardness and machinability. The Machining Doctor lists the machinability for material in 28 HRC, which is the lowest provided hardness (Also called Condition H1150).
The chart shows the hardness and machinability of the most common conditions:
Condition | Supplied Hardness (HRC) | Machinability |
---|---|---|
H1150 | 28 | 45% |
H1075 | 31 | 42% |
Condition A | 33 | 40% |
H1025 | 35 | 37% |
H900 | 43 | 31% |
The below recommendations apply to material in condition H1150 at a hardness of 28 HRC. The speeds should be adjusted according to the actual hardness!
For example, suppose you need to machine material in condition H900 (with hardness of 43 HRC). The above table shows that the machinability is 31% compared with 45% for 28 HRC. Therefore you need to multiply the recommended speed by 31/45=0.69
The best way is to use our Advanced Speed & Feed Calculator, where you can adjust the hardness slider, and the software will take it into account.
