ASTM A564 General scope :
ASTM A564(17-4 PH) is a precipitation hardening martensitic stainless steel, containing Copper. In the solution treated and doubled aged condition it has become the preferred alloy for Stems, Shafts, etc, and is used extensively in valve internals. High strength, including good properties up to 315°C (600°F) and excellent corrosion resistance (comparable to 304 austenitic stainless in many environments) makes this alloy extremely versatile.

In addition to limiting the hardness, NACE MR0175 restricts the age hardening cycles that can be applied to the alloy to two of the several available. NACE MR0175 only permits solution treatment, followed by double aging to either the H1150M condition 760°C (1400°F) / 620°C (1150°F) or the DH1150 condition 620°C (1150 °F) / 620°C (1150°F).
