In the world of advanced metallurgy and high-strength engineering, few documents are as frequently referenced as ASTM A564. The story usually begins the same way: an engineer, a procurement specialist, or a metallurgist sits at their desk, facing a critical design challenge. They need a material that is lighter than standard steel but stronger than aluminum—a material that can withstand immense stress while resisting corrosion. They turn to the search bar and type: "ASTM A564 PDF."
But this search is more than just a quest for a file; it is a quest for the blueprint of modern high-performance manufacturing.
The ASTM A564 PDF is more than just a file; it is the legal and technical requirement for manufacturing precipitation-hardening stainless steel components. Whether you are annealing 17-4 PH for machining or precipitating it to H900 for maximum strength, the standard is your map.
Invest the small fee to buy the official document. The cost of a counterfeit or obsolete PDF—failed parts, failed audits, and failed safety tests—is simply too high. Get the PDF, master the heat treatment tables, and build components that last.

Comprehensive Guide to ASTM A564: Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes
If you are searching for an ASTM A564 PDF, you are likely involved in high-performance engineering, aerospace, or chemical processing. ASTM A564 is the definitive industry standard covering age-hardening (precipitation-hardening) stainless steels. These materials are prized for their unique ability to achieve high strength and hardness through heat treatment while maintaining excellent corrosion resistance.
This article provides a deep dive into the specifications, grades, and applications covered by ASTM A564 to help you understand why this standard is critical for modern manufacturing. What is ASTM A564?
ASTM A564/A564M is a standard specification issued by ASTM International. It covers various forms of stainless steel, primarily bars and shapes, that are "age-hardening." Unlike standard 300-series stainless steels (which are hardened by cold working) or 400-series (hardened by quenching), A564 alloys use a specialized heat-treatment process called precipitation hardening. Key Characteristics: astm a564 pdf
High Strength: Can reach tensile strengths exceeding 150,000 psi.
Corrosion Resistance: Comparable to 304 stainless steel in many environments.
Dimensional Stability: Minimal distortion during the low-temperature aging process.
Versatility: Available in hot-rolled and cold-finished conditions. Common Grades under ASTM A564
The most recognizable grades within the ASTM A564 specification are the "17-4 PH" and "15-5 PH" varieties. 1. Type 630 (17-4 PH)
The "workhorse" of the precipitation-hardening family. It contains approximately 17% chromium and 4% nickel, with copper additions to facilitate hardening.
Best for: Pump shafts, valve components, and aerospace parts. 2. Type 631 (17-7 PH)
A chromium-nickel-aluminum alloy. It is known for high strength and fatigue resistance.
Best for: Springs and washers that operate at high temperatures. 3. XM-12 (15-5 PH)
A variant of 17-4 that offers better toughness and transverse properties. It is often used when a higher degree of structural integrity is required. 4. XM-13 (13-8 Mo)
Provides excellent toughness and resistance to stress-corrosion cracking in harsh environments. Understanding Heat Treatment Conditions
When reviewing an ASTM A564 PDF data sheet, you will encounter various "Conditions." These refer to the state of the metal following heat treatment:
Condition A (Solution Annealed): The material is soft and ready for machining or cold working. It has not yet been "aged."
Condition H900, H1025, H1150: The "H" stands for Hardened, followed by the temperature (in Fahrenheit) used for the aging process. A lower aging temperature (e.g., H900) results in higher hardness, while a higher temperature (e.g., H1150) results in better ductility and toughness. Chemical and Mechanical Requirements
To comply with ASTM A564, the material must meet strict chemical compositions and mechanical property benchmarks. Chromium (%) Nickel (%) Copper (%) Yield Strength (min) 630 (17-4) 15.0 – 17.5 3.0 – 5.0 3.0 – 5.0 145 ksi (H900) XM-12 (15-5) 14.0 – 15.5 3.5 – 5.5 2.5 – 4.5 145 ksi (H900)
Note: Always refer to the official ASTM A564 PDF for the most current and precise values, as standards are updated periodically. Applications of ASTM A564 Materials
Due to the balance of mechanical strength and chemical stability, these alloys are found in demanding sectors:
Aerospace: Landing gear components, engine parts, and structural fasteners.
Oil & Gas: High-pressure valves, pump shafts, and offshore platform hardware.
Medical: Surgical instruments and orthopedic implants where high hardness and sterilization resistance are required.
Food Processing: Gears and wear strips that must resist both corrosion and mechanical wear. Why You Need the Official ASTM A564 PDF
While summaries are helpful, engineers and procurement officers should always consult the full ASTM A564 PDF document for:
Permissible Variations: Understanding tolerances for diameter, thickness, and straightness.
Test Methods: Specific protocols for tension tests and impact tests.
Certification: Ensuring the Mill Test Report (MTR) aligns with the specific year-version of the standard. Conclusion
ASTM A564 is the cornerstone for anyone working with age-hardening stainless steel bars. Whether you are opting for the versatile 17-4 PH or the high-toughness 13-8 Mo, understanding the thermal processing and chemical limits defined by this standard is essential for project success.
