Astm A564 Pdf !!top!! Info
ASTM A564 (often searched as "ASTM A564 PDF" for reference manuals) covers a specific class of stainless steels known as precipitation-hardening (PH) stainless steels. Unlike standard austenitic (like 304 or 316) or martensitic (like 410) stainless steels, PH steels achieve exceptional strength and hardness through a specialized heat-treatment process called age hardening. The specification governs: Chemical composition limits
The (published November 2025), which supersedes all previous revisions.
One of the most valuable features of Type 630 is the ability to tailor its mechanical properties by selecting the appropriate aging condition. The table below shows specified properties for common conditions:
The ASTM A564 PDF provides the essential technical standard for anyone working with precipitation-hardening (age-hardening) stainless steel bar products, including common grades such as 17-4 PH (630), 17-7 PH (631), and 15-5 PH. This digital document is the current industry benchmark for specifying chemical composition, mechanical property requirements (heat-treated conditions), and dimensional tolerances. astm a564 pdf
In this condition, the material is in its softest state, ideal for . Type 630 in Condition A has a maximum hardness of approximately 39 HRC and is readily machinable.
Equipment requiring high durability and corrosion resistance. Key Technical Features
Most common grade; high strength, hardness, and corrosion resistance. S17700 ASTM A564 (often searched as "ASTM A564 PDF"
The defining feature of ASTM A564 materials is their ability to be heat treated to specific mechanical properties via .
| Element | Composition (%) | |:---|:---:| | Carbon (C) | 0.07 max | | Chromium (Cr) | 15.0 - 17.5 | | Nickel (Ni) | 3.0 - 5.0 | | Copper (Cu) | 3.0 - 5.0 | | Manganese (Mn) | 1.0 max | | Silicon (Si) | 1.0 max | | Columbium + Tantalum (Cb+Ta) | 0.15 - 0.45 | | Phosphorus (P) | 0.04 max | | Sulfur (S) | 0.03 max | | Iron (Fe) | Balance |
Note: Higher aging temperatures result in lower tensile strength but significantly improve ductility, impact toughness, and resistance to stress corrosion cracking. 5. Industrial Applications of ASTM A564 Material One of the most valuable features of Type
The standard specifically covers a class of specialty stainless steels known as age-hardening (or precipitation-hardening) stainless steels, which develop exceptional mechanical properties through controlled heat treatment. These materials offer a unique combination of high strength and corrosion resistance unavailable in conventional stainless grades.
