Because of their superior strength-to-weight ratio and corrosion resistance, materials manufactured according to ASTM A564 are used in critical applications:
A564/A564M Standard Specification for Hot-Rolled and Cold ... - ASTM
: Structural airframe components, fasteners, and engine parts.
(tensile strength, yield strength, hardness) for that grade.
To help clarify the landscape of stainless steel bar specifications, here is a comparison of ASTM A564 with other key standards: astm a564 pdf

The standard covers several grades, designated by their Chromium-Nickel content. The most common grades you will encounter are:
Highly formable in the annealed condition and develops exceptional mechanical properties after heat treatment.
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

The standard regulates standard shapes produced through hot rolling, extruding, or forging: Squares Hexagons Angles, tees, and channels Billets or bars intended for reforging Chemical Composition Requirements
: A complete, downloadable PDF version of an earlier revision (2002) is available via HTPipe , which includes the full scope, referenced documents, and detailed heat treatment tables. Major Alloys & Properties Covered
Approximately 17% Chromium and 4% Nickel, with copper addition. Common Designation: UNS S17400, AMS 5643, Grade 630.
Ferrite-free microstructure that eliminates directional variances in mechanical properties. The standard covers several grades, designated by their
, which are valued for their high strength and corrosion resistance. ASTM International Draft Summary: ASTM A564/A564M 1. Scope & Materials
. It primarily covers precipitation-hardening martensitic and austenitic stainless steels, most notably , which is commonly known as (UNS S17400). Zhengzhou Huitong Pipe Fittings Co.,Ltd. Key Specifications of ASTM A564 Material Types:
: Material is often purchased in the solution-annealed condition and then age-hardened to achieve specific mechanical properties (e.g., conditions H900, H1025, H1075, H1150 ). Mechanical Requirements : Specifies minimum values for: Tensile Strength : Often exceeding ] for certain conditions. Yield Strength : Often ] minimum for Condition H1075.
These are the most widely used grades under ASTM A564. They possess a martensitic structure in the annealed condition and achieve peak strength through low-temperature aging.
