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 . Key Characteristics:

If you are looking for the technical specifications, chemical compositions, and heat treatment procedures, downloading a detailed ASTM A564 pdf is often the first step in material selection.

Better structural homogeneity which reduces the risk of delamination in severe environments.

This table lists the exact recipe for each metal type. It dictates the maximum amounts of carbon, manganese, and phosphorus allowed in the mix. astm-a564.pdf

The integrity of your engineering project depends on having the exact, current, unaltered standard from ASTM International.

The Ultimate Guide to ASTM A564: Specifications, Grades, and PDF Resources

ASTM A564 standardizes several stainless steel grades, each designated by a "Type" or a Unified Numbering System (UNS) number. The most common and well-known grade is , which is frequently referred to by its trade name, 17-4PH (17% Chromium, 4% Nickel).
