standard specification for hot-rolled and cold-finished age-hardening stainless steel bars and shapes
. It is primarily used for high-performance applications that require a combination of high strength, hardness, and corrosion resistance. Titanium Industries, Inc. Key Specifications & Features Common Grades : The most widely recognized grade under this standard is , also known as (UNS S17400). Material Composition
: It covers chromium-nickel-copper precipitation-hardening martensitic stainless steels, often with niobium additions. Hardening Process
: Unlike standard stainless steels, these alloys achieve high tensile strength through a heat treatment process
that causes precipitation hardening of finely dispersed carbides. Applications
: It is frequently used in demanding industries such as aerospace, chemical processing, and marine environments where mechanical durability is critical. Stirlings Performance Steels Purchasing the Official PDF

ASTM A564 (often referred to with its metric equivalent ASTM A564M) is the
Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes
. It covers a variety of precipitation-hardening (PH) stainless steel grades, such as the widely used 17-4 PH (Type 630)
, which are valued for their high strength and corrosion resistance. ASTM International Draft Summary: ASTM A564/A564M 1. Scope & Materials
This specification covers bars and shapes including rounds, squares, hexagons, angles, tees, and channels. These materials can be produced via hot rolling, extruding, or forging. It is generally used for parts requiring high strength and corrosion resistance at temperatures up to: ASTM International 600°F (315°C) for most types. 700°F (370°C) for Type 632. 840°F (450°C) for Type UNS S46910. ASTM International 2. Common Grades
ASTM A564 includes several specialized PH stainless steel grades: Titanium Industries, Inc. Type 630 (UNS S17400): Commonly known as 17-4 PH. Type XM-12 (UNS S15500): Known as 15-5 PH. Type XM-13 (UNS S13800): Known as 13-8 PH. Type XM-25 (UNS S45000): Custom 450. Type 631 (UNS S17700): and corrosion resistance. Titanium Industries

Understanding ASTM A564: The Standard for High-Strength Age-Hardening Stainless Steel
In the world of high-performance engineering, finding a material that balances extreme strength with reliable corrosion resistance can be a challenge. That is where ASTM A564 comes into play. If you are looking for the "rulebook" on age-hardening stainless steel bars and shapes, this is the specification you need to know. What is ASTM A564?
ASTM A564 (often paired with its metric counterpart, SA-564M) is the standard specification for hot-rolled and cold-finished age-hardening stainless steel bars and shapes. It covers various product forms, including:
Shapes: Rounds, squares, hexagons, angles, tees, and channels.
Manufacturing Methods: These can be produced via hot rolling, extruding, or forging. Why "Age-Hardening"? including: Shapes: Rounds
The standout feature of the steels covered by this specification is their ability to be age-hardened (also known as precipitation hardening). This process involves heat treating the metal to significantly increase its yield strength and hardness without the risk of cracking or distortion that often plagues other high-strength steels. Popular Grades Under ASTM A564
While the specification covers several types, one name appears more than any other: Grade 630, better known as 17-4 PH (UNS S17400).
17-4 PH (Grade 630): A martensitic precipitation-hardening steel that offers an incredible combination of high strength and modest corrosion resistance. It is widely used in aerospace, chemical processing, and marine environments.
Type XM-25: Notable for being machinable even in its fully heat-treated condition.
Types 631 and 632: These contain higher levels of ferrite, meaning they are typically limited to smaller diameter bars to maintain ductility. Key Technical Requirements
