Meeting Global Standards: A Deep Dive into Waspaloy Alloy Bar Production per AMS5707P
ZYTC Alloy recently celebrated the successful completion and delivery of an order for Waspaloy (UNS N07001) round Bars to India. Produced under the stringent AMS5707P standard, these bars, with specifications of 17.1mm diameter and 2900mm length, underwent our rigorous, standardized, and specialized production and inspection processes to ensure they met all quality parameters before shipment. This milestone underscores our capability to manufacture high-quality Waspaloy products, including sheet, strip, wire, bar, and related items, in strict compliance with international standards such as ASTM, EN, and AMS, while offering competitive pricing and fast delivery cycles.
Introduction to Waspaloy (UNS N07001)
Waspaloy is a precipitation-hardenable, nickel-based superalloy renowned for its exceptional combination of high-temperature strength, excellent corrosion resistance, and outstanding oxidation resistance. It is capable of performing reliably in extreme environments, such as those encountered in aerospace and power generation applications, maintaining its mechanical properties even at temperatures exceeding 1000°F. This makes Waspaloy a material of choice for critical components in demanding industries.
Key Chemical Composition of Waspaloy
The superior properties of Waspaloy are derived from its carefully balanced chemical composition. The table below outlines the typical elemental content of this alloy.
| Element | Content (%) |
|---|---|
| Nickel (Ni) | Balance (approx. 56%) |
| Chromium (Cr) | 19 - 21 |
| Cobalt (Co) | 13.5 - 15 |
| Molybdenum (Mo) | 4.0 - 4.5 |
| Titanium (Ti) | 2.75 - 3.25 |
| Aluminum (Al) | 1.2 - 1.6 |
| Iron (Fe) | ≤ 2.0 |
| Silicon (Si) | ≤ 0.15 |
| Manganese (Mn) | ≤ 0.10 |
| Carbon (C) | 0.02 - 0.10 |
| Zirconium (Zr) | 0.02 - 0.12 |
| Boron (B) | 0.003 - 0.008 |
This composition provides Waspaloy with its signature high-temperature strength through gamma prime precipitation hardening, primarily via the Ni₃(Al, Ti) phase. Elements like chromium enhance its oxidation and corrosion resistance, while molybdenum and cobalt contribute to solid solution strengthening.
Mechanical and Physical Properties of Waspaloy
Waspaloy exhibits an impressive profile of mechanical properties, especially at elevated temperatures, as recognized by standards like AMS5707P.
Typical mechanical properties at room temperature in age-hardened condition include:
-
Tensile Strength: 1335 MPa (min)
-
Yield Strength (0.2% Offset): 910 MPa (min)
-
Elongation: 26.6% (min)
-
Elastic Modulus: 213 GPa
-
Hardness: 32 - 38 HRC
Key physical properties include:
-
Density: 8.20 g/cm³
-
Melting Point: 1330 - 1360 °C (approx. 2475 °F)
Its low thermal expansion coefficient and good thermal conductivity make it ideal for applications involving thermal cycling, such as in turbine engines. Furthermore, Waspaloy demonstrates remarkable creep and stress rupture strength at high temperatures, outperforming other common alloys like 718 in the 1300-1500°F range.
Primary Applications and Uses of Waspaloy
The unique properties of Waspaloy make it indispensable in several high-performance industries. Our products, like the exported round bar, are fundamental in manufacturing critical components in:
-
Aerospace & Jet Engines: Used for turbine blades, compressor discs, shafts, seals, rings, spacers, and combustion chamber components.
-
Gas Turbines: Employed in buckets, nozzles, and fasteners for both aviation and land-based power generation turbines.
-
Industrial Equipment: Used in high-strength fasteners, chemical processing equipment, and components for oil and gas exploration.
