Astm A564 Pdf ((link)) Official
The PDF details the "aging" process. Unlike standard steels that are hardened by quenching (rapid cooling), A564 steels are hardened by holding them at moderate temperatures (900°F to 1150°F) for an hour. This causes microscopic particles to "precipitate" out of the metal matrix, locking the structure in place and dramatically increasing strength. The PDF provides the precise temperatures and times required to achieve conditions like H900 (highest strength) or H1150 (more ductile).

If you are looking for the ASTM A564 standard in PDF format, you are likely involved in the selection, testing, or specification of high-strength precipitation-hardening stainless steels. The PDF details the "aging" process
The standard covers numerous grades (630, 631, 632, 635, etc.), but two dominate the market: The PDF provides the precise temperatures and times
The is the standard specification for hot-rolled and cold-finished age-hardening stainless steel bars and shapes . It covers a variety of corrosion-resistant and high-strength steels, most notably Grade 630 (commonly known as 17-4 PH stainless steel). Core Content of ASTM A564
