Pdf: Astm A564

While summaries are helpful, engineers and procurement officers should always consult the full document for:

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.

For the absolute latest version (e.g., A564/A564M-19), it is recommended to purchase directly from the ASTM International official site for specific heat-treat conditions like astm-a564.pdf

The ASTM A564 standard outlines stringent requirements for the material's performance. Key mechanical properties that must be verified are:

Hot-finished or cold-finished bars, including rounds, squares, hexagons, and other structural shapes. astm a564 pdf

(tensile strength, yield strength, hardness) for that grade.

A modification of 17-4 PH designed to provide greater toughness and better transverse properties.

is a critical material specification in the stainless steel industry, governing hot-rolled and cold-finished precipitation-hardening (age-hardening) stainless steel bars, rods, wire, and structural shapes. These materials are designed to provide high strength, excellent corrosion resistance, and good machinability, making them indispensable in aerospace, chemical processing, and high-performance engineering applications. 1. Scope of ASTM A564

Don’t confuse A564 with A484. A564 covers age-hardened bars; A484 covers general requirements for stainless bars (non-hardened). Key mechanical properties that must be verified are:

The most widely used age-hardening stainless steel. It offers an excellent balance of high strength, hardness, and moderate corrosion resistance. Grade 631 (17-7 PH) UNS Designation: S17700 Composition: 17% Chromium, 7% Nickel, 1.2% Aluminum.

This comprehensive guide covers everything you need to know about the ASTM A564 specification, including its applications, chemical composition, and mechanical properties. To access the official, complete technical document, you can often find the through various technical standard suppliers.

The specification covers produced by hot rolling, extrusion, or forging. Billets or bars for reforging may also be purchased under this specification.

A double-aging process used to achieve the most compliant, machinable state for severe forming operations. Mechanical Properties is a critical material specification in the stainless

If you work in aerospace, defense, oil & gas, or high-stress fasteners, you have likely typed 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.

Often available through company library subscriptions (e.g., IHS Markit).

While ASTM A564 includes several specialized alloys, a few prominent grades dominate industrial applications: Type 630 (17-4 PH) S17400
