The DIN/EN equivalents (1.4542, X5CrNiCuNb16‑4) are commonly used in European specifications, while AMS 5643 and AMS 5644 govern aerospace applications.
| Element | Composition (%) | |---|---| | Carbon (C) | ≤ 0.07 | | Manganese (Mn) | ≤ 1.00 | | Silicon (Si) | ≤ 1.00 | | Phosphorus (P) | ≤ 0.040 | | Sulfur (S) | ≤ 0.030 | | Chromium (Cr) | 15.00–17.50 | | Nickel (Ni) | 3.00–5.00 | | Copper (Cu) | 3.00–5.00 | | Niobium + Tantalum (Nb+Ta) | 0.15–0.45 |
This comprehensive guide covers everything you need to know about the ASTM A564 specification, including its applications, chemical composition, and mechanical properties.

: High-pressure pump shafts, valves, and mixer impellers.
Higher aging temperatures (H1025, H1150) produce slightly lower strength but significantly . Lower temperatures (H900) yield maximum hardness and strength. The DIN/EN equivalents (1
This is the most popular precipitation-hardening grade. It contains approximately 17% chromium and 4% nickel, supplemented with copper.
The ASTM A564 standard covers standard requirements for age-hardening (precipitation-hardening) stainless steel bars, wires, and shapes. These materials are unique because they combine the excellent corrosion resistance of stainless steel with ultra-high mechanical strength achieved through heat treatment. Key Characteristics Covered: : High-pressure pump shafts, valves, and mixer impellers
This article provides a deep dive into the specifications, grades, and applications covered by ASTM A564 to help you understand why this standard is critical for modern manufacturing. What is ASTM A564?
