Mechanical properties under ASTM A564 vary significantly based on the aging temperature: Astm A564-10 | PDF | Forging | Stainless Steel - Scribd
Available in various conditions (Condition A, H900, H1025, etc.) to meet specific hardness and toughness requirements. Common Grades Covered Type 630 (17-4 PH):
: Various historical versions and summaries can be found on Scribd for quick viewing of table structures and standard sections. Common Heat Treatment Conditions (17-4 PH)
Pump shafts, valve trim, oil field wellhead components, and offshore sensor housings. astm a564 pdf
Grades like 17-4 PH resist corrosive attack better than standard hardenable chromium stainless steels (like 410 or 440C) and match 304 stainless steel in most atmospheric environments.
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.
Pump shafts, valve components, and aerospace parts. 2. Type 631 (17-7 PH) Grades like 17-4 PH resist corrosive attack better
Note: Always verify the specific "Condition" (e.g., Condition H1150) required for your application, as the mechanical properties vary significantly based on the heat treatment cycle. for a specific grade like under this standard?
Here is the full story and context behind the search term explaining what the standard is, why the PDF format is sought after, and the technical details contained within the document.
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 Condition H1150) required for your application

Engineers specify ASTM A564 alloys over standard carbon steels or other stainless steel families due to three distinct advantages:
The ASTM A564 specification is the standard reference for hot-rolled and cold-finished age-hardening stainless steel bars and shapes. Engineers, machinists, and procurement specialists rely on this standard to select high-strength, corrosion-resistant materials for critical industrial applications.
Understanding the surrounding specification landscape is critical for full compliance. Several other ASTM standards are referenced within A564:
covers martensitic and austenitic precipitation-hardening stainless steel bars and shapes. The primary goal of this material is to provide high strength and hardness combined with excellent corrosion resistance. Key characteristics detailed in the ASTM A564 pdf include:
