The specification places a clear responsibility on the purchaser to specify all necessary requirements when ordering material to this standard. To avoid confusion and ensure you get the correct product, an order must include [quoted from ASTM A564-02a language]:
The is the standard specification for hot-rolled and cold-finished age-hardening stainless steel bars and shapes . It is a critical reference for materials requiring high strength and corrosion resistance, most notably the 17-4 PH (Grade 630) alloy. Core Specification Scope
Unlike standard austenitic stainless steels (like 304 or 316) which cannot be hardened by heat treatment, ASTM A564 materials utilize alloying elements like copper, aluminum, titanium, or niobium to form microscopic precipitates. These precipitates block dislocations in the crystal lattice, drastically increasing the yield strength and hardness of the metal. Common Material Grades Covered
This chromium-nickel-aluminum stainless steel offers high strength and hardness alongside excellent fatigue properties. astm a564 pdf
Available for direct digital download or hardcopy purchase.
. It covers a variety of precipitation-hardening (PH) stainless steel grades, such as the widely used 17-4 PH (Type 630)
For a long article covering "astm a564 pdf," it must be understood that "PDF" refers to the official, copyrighted document. While you can find many resources online, the definitive source of truth is always the authorized PDF purchased from ASTM International or its partners. Using the correct and current version of the standard is not just a formality; it is a critical step in ensuring safety, quality, and legal compliance in any engineering project. By understanding the scope, grades, and proper procurement channels for ASTM A564, you are well-equipped to make informed decisions and specify materials with complete confidence. The specification places a clear responsibility on the
The aging temperatures dictate the final mechanical properties and are designated by the letter "H" followed by the Fahrenheit aging temperature:
: Detailed tables for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, and copper (the primary age-hardening element in 17-4 PH). Typical Document Structure A standard PDF of this specification typically includes: ASTM A564 Specification for Stainless Steel | PDF - Scribd
Trusted technical document clearinghouses like IHS Markit, Techstreet, and ANSI also sell authorized, authenticated copies of the standard. Available for direct digital download or hardcopy purchase
covers martensitic and austenitic precipitation-hardening stainless steel bars and shapes. The primary goal of this material is to provide high strength and hardness combined with excellent corrosion resistance. Key characteristics detailed in the ASTM A564 pdf include:
The ASTM A564 specification encompasses several distinct metallurgical grades. The most widely utilized commercial grades include: Grade 630 (17-4 PH)
ASTM A564 is the go-to standard for Precipitation-Hardening Stainless Steel bars. If you are machining parts like pump shafts, landing gear components, or high-strength fasteners, you are likely looking at . When reviewing the PDF, pay close attention to the Condition (H900, H1150, etc.) , as this dictates the final strength and hardness of the part.
