Astm A564 Pdf -
Due to the balance of mechanical strength and chemical stability, these alloys are found in demanding sectors:
Understanding the ASTM A564 specification is essential for engineers designing high-performance machinery. By utilizing the proper heat-treatment conditions specified in the standard, manufacturers can achieve the necessary balance of high strength, toughness, and corrosion resistance for their specific application.
Frequently, engineers look for because a drawing calls it out. However, you might have an international supplier. Here is the cross-reference: astm a564 pdf
| ASTM Type | Common Name | UNS Designation | Key Characteristics | |---|---|---|---| | | 17‑4PH | S17400 | Chromium‑nickel‑copper grade; most widely used PH stainless steel; excellent strength and corrosion resistance | | 631 | 17‑7PH | S17700 | Chromium‑nickel‑aluminum grade; outstanding fatigue resistance; ideal for springs and diaphragms | | 632 | – | S15700 | Similar to 631; contains ferrite; low ductility in large diameters | | XM‑16 | – | S13900 | High‑strength grade for specialized applications | | XM‑25 | – | S17400 | Variant of Type 630, machinable in the fully heat‑treated condition | | UNS S46910 | – | S46910 | Developed for high‑temperature service up to 840 °F (450 °C) |
The most recognizable grades within the ASTM A564 specification are the "17-4 PH" and "15-5 PH" varieties. 1. Type 630 (17-4 PH) Due to the balance of mechanical strength and
Materials under this standard are valued for their ability to achieve a wide range of mechanical properties through different heat treatment "ages" (e.g., H900, H1050, H1150). Description Tensile Strength High strength achieved via precipitation hardening. Corrosion Resistance Comparable to 304 stainless steel in most environments. Fabrication
Common heat treatment conditions include , each offering different combinations of strength, ductility, and toughness. However, you might have an international supplier
(tensile strength, yield strength, hardness) for that grade.
A crucial note for designers and manufacturers: these steels are generally suitable for machining in the solution-annealed condition, after which they may be age-hardened to full mechanical properties without danger of cracking or distortion. Some types, such as XM-25, are machinable in the as-received, fully heat-treated condition, while others, like UNS S46910, can be machined in the solution-annealed, cold-worked, or age-hardened states.
