Astm A564 Pdf

Buy the official ASTM A564 PDF if you are a machine shop, aerospace supplier, or quality lab that regularly certifies 17-4 PH or 15-5 PH material. It is a non-negotiable tool for passing ISO or AS9100 audits.

However: If you only need to look up one hardness value for a hobby project, try to borrow a copy from a local technical library or a client. The price is steep for casual use.

Pro Tip for Buyers: Always purchase directly from the ASTM International website or an authorized reseller (Techstreet, IHS). Avoid random astm a564 pdf downloads from file-sharing sites—those are often outdated, watermarked, or riddled with OCR errors.

Final Score: 9/10 (Deducted 1 point for high cost and version confusion risk).

When a user finally opens the ASTM A564 PDF, they are met with a dense, technical manuscript. It is not a narrative story, but a story of chemistry and physics. The document is typically divided into critical sections:

1. The Classification (Grades) The heart of the PDF is the list of grades. These aren't random numbers; they are distinct chemical recipes. The most famous characters in this story are:

2. The Process (Heat Treatment) 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).

3. The Mechanicals The document dictates the minimum requirements for Tensile Strength, Yield Strength, Elongation, and Hardness. For example, a user consulting the PDF for Grade 630 in condition H900 will see that it requires a minimum tensile strength of 190,000 psi—making it nearly four times stronger than standard mild steel.

Once you open the official ASTM A564 PDF, do not skim. Lock in on these sections:

When you open your ASTM A564 PDF, you will find detailed tables. Here is a preview of the data you need to look for regarding Grade 630 Condition H900 (the most common specification):

Note: If you are using Condition H1150, these numbers drop significantly (Tensile ~795 MPa) in exchange for much higher ductility.

ASTM A564 is a widely used specification covering stainless steel bars, billets, and forgings that are produced by hot working and cold finishing processes. It primarily addresses high-strength, high-chromium, nickel, and other alloy stainless steels supplied in round, square, hex, and flat shapes for applications requiring excellent mechanical properties and corrosion resistance.

ASTM A564 provides a comprehensive framework for procuring high‑strength stainless steel bars and forgings with predictable chemical composition, mechanical properties, and quality assurance. Correct specification of grade, heat treatment, surface finish, and testing obligations ensures material performance in demanding applications such as aerospace, petrochemical, and high‑pressure mechanical systems.

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. astm a564 pdf

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:

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)
