ASTM A564 is the essential specification for age‑hardening stainless steel bars and shapes, providing the foundation for high‑performance components across aerospace, chemical, oil and gas, and marine industries. Whether you need the exceptional strength of Type 630 (17‑4PH) for pump shafts and fasteners or the fatigue resistance of Type 631 (17‑7PH) for springs and diaphragms, A564 offers the guidelines and quality assurance required for demanding applications. astm a564 pdf
To help clarify the landscape of stainless steel bar specifications, here is a comparison of ASTM A564 with other key standards:

Materials specified under ASTM A564 are generally shipped in (Solution Treated). In Condition A, the material is soft and easily machined or formed. After fabrication, components are aged to achieve specific mechanical targets, designated by the aging temperature in Fahrenheit (e.g., H900, H1050, H1150). Mechanical Property Targets for Grade 630 (17-4 PH) Condition A (Solution Treated): Tensile Strength: Typically around 150 ksi (1034 MPa) Hardness: Max 363 HBW / 38 HRC Condition H900 (Aged at 900°F / 482°C): Tensile Strength (min): 190 ksi (1310 MPa) Yield Strength (min): 170 ksi (1170 MPa) Elongation in 2 in. (min): 10% Condition H1050 (Aged at 1050°F / 566°C): Tensile Strength (min): 145 ksi (1000 MPa) Yield Strength (min): 135 ksi (930 MPa) Elongation in 2 in. (min): 12% Condition H1150 (Aged at 1150°F / 621°C): Tensile Strength (min): 135 ksi (930 MPa) Yield Strength (min): 105 ksi (724 MPa) Elongation in 2 in. (min): 16%
The ASTM Committee A01 on Steel, Stainless Steel, and Related Alloys actively maintains this standard, with proposed revisions often under development (as evidenced by work item WK87171 from 2023). To help clarify the landscape of stainless steel
Unlike standard austenitic stainless steels (like 304 or 316), which can only be hardened by cold working, ASTM A564 alloys achieve their superior mechanical properties through low-temperature thermal aging treatments. 2. Common Grades Covered by ASTM A564
