In the world of precision engineering, aerospace components, and high-stress industrial applications, material specifications are the bedrock of safety and performance. One of the most critical standards for precipitation-hardening stainless steels is ASTM A564.
If you have been searching for the term "ASTM A564 PDF", you are likely an engineer, a quality assurance manager, or a procurement specialist who needs immediate access to the official documentation. This article will explain everything you need to know about the ASTM A564 standard, its grades, mechanical properties, and—most importantly—how and where to legally obtain the official PDF.
Because precipitation-hardening steels are magnetic (unlike 304), they are used in food cutting blades where sanitation is critical, but magnetic separation is needed.
If you work in aerospace, defense, oil & gas, or high-stress fasteners, you have likely typed “ASTM A564 PDF” into a search engine at least once. You need the standard—fast. But beyond just downloading the document, understanding what makes this specification critical can save your project from catastrophic failure.
Let’s break down the “why” behind ASTM A564, its most popular grades (17-4 PH, 15-5 PH), and how to legally access the official PDF.
Downloading the ASTM A564 PDF is step one. Step two is applying it correctly. Whether you are ordering 17-4 PH bars for a hydraulic manifold or 15-5 PH for a landing gear component, remember that precipitation hardening is a precise science.
Don’t gamble with free, outdated PDFs. Spend the $60. Your liability insurance will thank you.

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:
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: Have a specific question about ASTM A564 heat
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.
