To understand the document, one must understand the material. is the standard specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes .

These steels can reach tensile strengths exceeding 150,000 psi after age-hardening. Corrosion Resistance:

A particularly important caution appears in the specification:

: Aged at 1025°F (552°C). Offers a balance of high strength and moderate ductility. astm a564 pdf

: For a summary of the scope, chemical composition, and mechanical properties, Scribd's ASTM A564 Overview provides a structured look at the document.

The "H" denotes the hardened state, and the number signifies the aging temperature in degrees Fahrenheit.

For engineers, procurement specialists, and quality managers in high‑stakes industries—aerospace, chemical processing, oil and gas, and marine engineering—understanding the ASTM A564 specification is essential. This comprehensive guide explores every aspect of ASTM A564, from the standard’s technical scope and material grades to the most practical ways to for your reference library.

The standard outlines several specific heat treatment designations. The letter followed by a number indicates the aging temperature in degrees Fahrenheit: To obtain an official, legally compliant, and up-to-date

Comparable to 304 stainless steel in many environments.

ASTM A564 is a standard specification for age-hardening stainless steel bars and shapes. The specification covers various grades of stainless steel, including 630, 631, 634, 635, and 637, which are commonly used in aerospace, chemical processing, and other industries.

The primary grade under this specification is , commonly called 17-4 PH: Weight % (Type 630 / 17-4 PH) Chromium (Cr) 15.00 – 17.50% Nickel (Ni) 3.00 – 5.00% Copper (Cu) 3.00 – 5.00% Niobium + Tantalum (Nb + Ta) 0.15 – 0.45% Manganese (Mn) Silicon (Si) Carbon (C)

A crucial note for designers and manufacturers: these steels are generally suitable for machining in the solution-annealed condition, after which they may be age-hardened to full mechanical properties without danger of cracking or distortion. Some types, such as XM-25, are machinable in the as-received, fully heat-treated condition, while others, like UNS S46910, can be machined in the solution-annealed, cold-worked, or age-hardened states. The "H" denotes the hardened state, and the

This means these grades are best suited for small‑diameter bars and wire forms, such as springs, rather than large forgings or heavy structural sections.

The PDF specifies the resistance to sulfide stress corrosion cracking (SSCC). Grade 630 in Condition H1150 is the go-to material for valve stems and fasteners in sour gas environments (H2S).

yields the highest tensile strength but lower impact toughness.
