(angles, tees, and channels). 2. Common Material Grades Covered
Structural components, landing gear components, fasteners, and engine valves where strength-to-weight ratio is vital.
ASTM A564 materials are widely used in various industries, including:
The material is chosen for its superior strength-to-weight ratio and resistance to corrosion, useful at temperatures up to 600∘F600 raised to the composed with power F 315∘C315 raised to the composed with power C 2. Chemical Composition and Heat Treatment astm a564 pdf
While a free, current PDF is challenging to obtain, legitimate avenues exist through the ASTM Reading Room, university subscriptions, and direct purchase from authorized retailers. Always ensure you are referencing the correct, current version of the standard for your professional applications. Whether you are specifying materials for an aerospace fastener or a high-performance pump shaft, a thorough understanding of ASTM A564 is your foundation for success.
Other grades include Type 631, Type 632, UNS S46910, and custom grades like Custom 465 (1.4614). These alloys offer specialized properties, such as higher temperature resistance or enhanced toughness, and are often used in demanding aerospace applications.
Aged at 900°F. This provides the highest ultimate tensile strength but lower impact toughness. (angles, tees, and channels)

Ideal for severe environments requiring high structural integrity, such as aircraft components and high-pressure chemical systems. 4. XM-13 (13-8 Mo)
Hot-finished or cold-finished bars, including rounds, squares, hexagons, and other structural shapes. ASTM A564 materials are widely used in various
Type 630 is by far the most widely used grade, commonly known as 17-4 PH stainless steel. It is a martensitic precipitation-hardening stainless steel containing copper and is known for its outstanding combination of high strength, good corrosion resistance (comparable to Type 304 austenitic stainless in many environments), and mechanical properties up to 600°F (316°C). The alloy's name reflects its approximate composition of 17% chromium and 4% nickel, with additional copper and columbium.
