ASTM A564 covers a wide variety of wrought product forms. These include hot-finished or cold-finished rounds, squares, hexagons, bar shapes, angles, tees, and channels. They can be produced by hot rolling, extruding, or forging. Billets or bars for reforging may also be purchased to this specification.
The ASTM A564 standard is regularly updated, with versions like 2013, 2019a, and 2025 appearing in searches.
| Condition | Tensile Strength (MPa) | Yield Strength, 0.2% (MPa) | Elongation (%) | |---|---|---|---| | H900 | 1,310 | 1,172 | 10 | | H925 | 1,172 | 1,069 | 10 | | H1025 | 1,069 | 1,000 | 12 | | H1075 | 1,000 | 862 | 13 | | H1100 | 965 | 793 | 14 | | H1150 | 931 | 724 | 16 |
The standout feature of ASTM A564 materials is their ability to be machined easily in a softer, solution-annealed state (Condition A) and subsequently hardened via low-temperature thermal aging. Because aging temperatures are relatively low (900°F to 1150°F), parts experience minimal distortion and scaling compared to traditional quench-and-temper martensitic steels. astm a564 pdf
Landing gear parts, high-strength bolts.
This grade is semi-austenitic, meaning it is austenitic in the annealed state but martensitic in the hardened state. It is known for exceptional fatigue resistance and is frequently used for springs and deep-drawn parts. XM-12 (15-5 PH) UNS Designation: S15500
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: ASTM A564 covers a wide variety of wrought product forms
: Aged at 900°F (482°C). Provides the highest tensile strength but lower impact toughness.
While the ASTM A564 document regulates dozens of specialized alloy variations, a few distinct grades dominate industrial manufacturing: Grade 630 (Type 17-4PH)
