. 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
To help clarify the landscape of stainless steel bar specifications, here is a comparison of ASTM A564 with other key standards:
ASTM A564 (often referred to with its metric equivalent ASTM A564M) is the
Mixers, impellers, high-pressure valves, and chemical reactor parts.
Other prominent grades governed by this PDF include Type 631 (UNS S17700), XM-12 (UNS S13800), and XM-13 (UNS S14800). Heat Treatment Conditions astm a564 pdf

For example, 17-4 PH in the H900 condition can reach a tensile strength of approximately 1355 MPa and a yield strength of 1020 MPa.
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
The ASTM A564 standard includes several grades, with 17-4PH being the most common. 1. ASTM A564 Type 630 (17-4PH) Key Specifications & Features Common Grades : The
A chromium-nickel-aluminum alloy. It is known for high strength and fatigue resistance.
Mixers, heat exchanger components, and storage vessel fixtures exposed to corrosive compounds.
The specification covers several distinct types of precipitation-hardening (PH) stainless steels, categorized by their final crystalline structures (martensitic, semi-austenitic, or austenitic). Grade 630 (17-4 PH) S17400 Composition: 17% Chromium, 4% Nickel, 4% Copper.
Yields the highest tensile strength and hardness but the lowest ductility and impact toughness. Heat Treatment Conditions If you need help determining
Hardness typically ranges from 35-43 HRC (Rockwell C) for the H900 condition.
Because ASTM A564 materials handle intense mechanical loads without succumbing to oxidation or environmental degradation, they are found in highly demanding environments:
