Aged at 900°F (482°C) for 1 hour, air cool. This provides the highest tensile strength and hardness, but the lowest impact toughness.
Pump shafts, aerospace components, oilfield tools, and chemical processing equipment. 2. ASTM A564 Type 631 (17-7PH) astm a564 pdf
ASTM A564, formally titled the "Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes", is a globally recognized standard developed by ASTM International. First approved in 1966, it has been updated several times, with notable recent editions from 2019 and a new 2025 version that ensures the specification remains current with industry needs.
A semi-austenitic precipitation-hardening steel known for high strength and hardness, excellent fatigue properties, and good corrosion resistance. 3. ASTM A564 Type XM-25 [Current Date] Aged at 900°F (482°C) for 1
These steels are generally supplied in the solution-annealed condition and then age-hardened to achieve specific mechanical properties without significant distortion or cracking. Common Heat Treatments: Solution Annealed (Condition A): The initial state.
The specification provides critical technical data required for manufacturing and procurement: Chemical Processing: Agitators
Due to its robust mechanical profile, ASTM A564 material is frequently found in: Aerospace: Structural parts and engine components. Oil & Gas: High-pressure valves, shafts, and offshore equipment. Chemical Processing: Agitators, bolts, and specialized fittings. Surgical instruments and orthopedic implants. Technical Documentation and PDF Access When looking for the ASTM A564 PDF
